Abstract
INTRODUCTION In recent years cepstral analysis and specific cepstrum-based measures such as smoothed cepstral peak prominence (CPPS) has become increasingly researched and utilized in attempts to determine the extent of overall dysphonia in voice signals. Yet, few studies have extensively examined how specific voice-source parameters affect CPPS values. OBJECTIVE Using a range of synthesized tones, this exploratory study sought to systematically analyze the effect of fundamental frequency (fo), vibrato extent, source-spectrum tilt, and the amplitude of the voice-source fundamental on CPPS values. MATERIALS AND METHODS A series of scales were synthesised using the freeware Madde. Fundamental frequency, vibrato extent, source-spectrum tilt, and the amplitude of the voice-source fundamental were systematically and independently varied. The tones were analysed in PRAAT, and statistical analyses were conducted in SPSS. RESULTS CPPS was significantly affected by both fo and source-spectrum tilt, independently. A nonlinear association was seen between vibrato extent and CPPS, where CPPS values increased from 0 to 0.6 semitones (ST), then rapidly decreased approaching 1.0 ST. No relationship was seen between the amplitude of the voice-source fundamental and CPPS. CONCLUSION The large effect of fo should be taken into account when analyzing the voice, particularly in singing-voice research, when comparing pre and posttreatment data, and when comparing inter-subject CPPS data.

Abstract
BACKGROUND This study investigates the relationship between professional and recreational singing on temporomandibular disorders (TMDs) in women compared to a nonsinging control group. METHODS A total of 288 female subjects between the ages of 18 and 45 participated in the self-assessment questionnaire including demographic data, as well as questions on vocal practice and TMDs symptoms. Depending on the singing time per week, the (non)vocalists were assigned to the groups professional (n = 96), recreational (n = 96) and nonsingers (n = 96). RESULTS The TMDs prevalence in professional singers (42%) was higher than that in recreational singers (31%) and noticeably higher than that in nonsingers (25%). The Fisher-Freeman-Halton exact test showed that the differences between the groups were not noticeable (p = .053) but could be formulated as tendencies. The professionals suffered much more from restricted jaw movement (p = .004; OR = 2.718; 95% CI = 1.409-5.242), temporomandibular joint sounds (p < .009; OR = 2.267; 95% CI = 1.264-4.064) and temporomandibular pain (p = .010; OR = 2.333; 95% CI = 1.264-4.308) than nonsingers. CONCLUSIONS Singing might have an enhancing effect on the appearance of TMDs. In particular, professional singers suffered more from self-reported TMDs than recreational singers and nonsingers. In addition to the high level of physical workload if participating in professional singing, the psychosocial impact should be investigated more in further studies. No new treatment strategies resulted from this study, as the etiological significance of singing is still unclear. Knowledge about risk factors for multifactorial TMDs can help practitioners and patients prevent and treat TMDs.

Abstract
The choice of terms to describe and assess the singing voice is an essential part of vocal pedagogy. However, previous work suggested that singing terminology used in academia may be somewhat ambiguous. To address this issue, the authors a) compiled a comprehensive inventory of singing voice assessment terms used by English-speaking academic institutions worldwide and b) with the help of 22 highly experienced singing voice teachers, grouped the most prevalent terms based on their conceptual similarity. Only about a fifth of all targeted institutions provided materials and information online. Overall, a total of 292 different terms were found in the 64 available sources. This surprisingly large number of terms could be reduced by approximately 61% through lexical grouping. In the resulting data set, only 24 of the 114 terms occurred in at least 20% of the online sources, suggesting a rather low current density of information as well as little to no systematic and coordinated use of terms across institutions. The singing voice expert's similarity rating of the 24 most prevalent terms revealed a non-uniform distribution, suggesting that only some of these terms can be used interchangeably. Overall, these findings hint at the underlying complexity of voice assessment on a descriptive and qualitative level, highlighting the need for further research in this area.

Abstract
Sentence repetition has been the focus of extensive psycholinguistic research. The notion that music training can bolster speech perception in adverse auditory conditions has been met with mixed results. In this work, we sought to gauge the effect of babble noise on immediate repetition of spoken and sung phrases of varying semantic content (expository, narrative, and anomalous), initially in 100 English-speaking monolinguals with and without music training. The two cohorts also completed some non-musical cognitive tests and the Montreal Battery of Evaluation of Amusia (MBEA). When disregarding MBEA results, musicians were found to significantly outperform non-musicians in terms of overall repetition accuracy. Sung targets were recalled significantly better than spoken ones across groups in the presence of babble noise. Sung expository targets were recalled better than spoken expository ones, and semantically anomalous content was recalled more poorly in noise. Rerunning the analysis after eliminating thirteen participants who were diagnosed with amusia showed no significant group differences. This suggests that the notion of enhanced speech perception-in noise or otherwise-in musicians needs to be evaluated with caution. Musicianship aside, this study showed for the first time that sung targets presented in babble noise seem to be recalled better than spoken ones. We discuss the present design and the methodological approach of screening for amusia as factors which may partially account for some of the mixed results in the field.

Abstract
BACKGROUND This paper considers weaknesses in a study by Cohen et al. (2006) on the impacts of community singing on health. These include high demand characteristics, lack of attention to attrition, flawed statistical analysis, and measurement. Nevertheless, the study is uncritically cited, in evidence reviews, with findings taken at face value. METHODS Google Scholar, SCOPUS and BASE citation functions for Cohen et al. identified 32 evidence reviews in peer-reviewed journals. Eleven of these reviews, published between 2010 and 2023, focused on creative arts interventions. RESULTS We demonstrate limitations in the Cohen et al. research which undermine the conclusions they reach regarding the health benefits of group singing. Subsequent evidence reviews take the findings at face value and offer little critical commentary. DISCUSSION We consider what is needed to improve evidence reviews in the field of creative arts and health research. CONCLUSIONS A more robust approach is needed in reviewing research evidence in the field of arts and health. The Cohen et al. paper is not suitable for inclusion in future evidence reviews.

Abstract
OBJECTIVE To document and quantify vocal dose and student-singers' self-assessment during rehearsals for a contemporary musical theater production. METHODS/DESIGN Six student singers fastened the sensor from the KayPentax APM 3200 dosimeter to the lower neck to capture neck vibration data during their preparation for the musical Wonderland by Frank Wildhorn. Data were collected during 8-hour periods, at four different stages throughout the rehearsal process: beginning (music and choreography learning phase), middle (staging phase), and end (running the entire show/dress rehearsal phase), plus a post-production day once the production had concluded to establish a baseline vocal load. Students concurrently completed the EASE questionnaire1 after each data collection day. RESULTS The EASE score (Appendix 1) and demographics/perceptual questionnaire (Appendix 2) revealed that all subjects (three males and three females) found the singing role vocally and physically demanding but only two found the roles to be emotionally challenging. The musical score demanded a higher usage of chest register (judged perceptually) than mixed register from lead singers. All subjects' maximum fundamental frequency range exceeded the pitch range required by the score. The mean daily vibration dose (distance dose, as computed with Kay Pentax Software) of the three individual female singers' during rehearsals, 5,203 meters, was higher than the mean daily dose of the three male singers, 3,766 meters. The subjects' self-ratings on the EASE were not correlated with the distance dose. CONCLUSIONS A review of Wonderland's score and perceptual judgment of the singers' performances revealed extensive use of chest register, with belting and mix vocal strategies being the predominant stylistic choices. Students described the singing roles' vocal and physical requirements as more challenging than the character's emotional components. This pilot study provides information on the vocal dose for lead and ensemble singers in rehearsal for a Contemporary Musical Theatre production. Singers and voice professionals may find dosimetry a valuable tool for monitoring the vocal dose during rehearsals and performances.

Abstract
BACKGROUND During the Covid-19 pandemic, singing activities were restricted due to several super-spreading events that have been observed during rehearsals and vocal performances. However, it has not been clarified how the aerosol dispersion, which has been assumed to be the leading transmission factor, could be reduced by masks which are specially designed for singers. MATERIAL AND METHODS Twelve professional singers (10 of the Bavarian Radio-Chorus and two freelancers, seven females and five males) were asked to sing the melody of the ode of joy of Beethoven's 9th symphony "Freude schöner Götterfunken, Tochter aus Elisium" in D-major without masks and afterwards with five different singers' masks, all distinctive in their material and proportions. Every task was conducted after inhaling the basic liquid from an e-cigarette. The aerosol dispersion was recorded by three high-definition video cameras during and after the task. The cloud was segmented and the dispersion was analyzed for all three spatial dimensions. Further, the subjects were asked to rate the practicability of wearing the tested masks during singing activities using a questionnaire. RESULTS Concerning the median distances of dispersion, all masks were able to decrease the impulse dispersion of the aerosols to the front. In contrast, the dispersion to the sides and to the top was increased. The evaluation revealed that most of the subjects would reject performing a concert with any of the masks. CONCLUSION Although, the results exhibit that the tested masks could be able to reduce the radius of aerosol expulsion for virus-laden aerosol particles, there are more improvements necessary to enable the practical implementations for professional singing.

Abstract
OBJECTIVE to compare the self-perception of vocal fatigue and use of singing voice during the COVID-19 pandemic between professional and amateur singers and to relate this self-perception with vocal use characteristics during this period. METHODOLOGY Participants were 121 singers divided into professional singers group (PSG) (12 men and 20 women) comprising singers who depended exclusively on singing as a profession and an amateur singers group (ASG) (37 men and 52 women) of singers who did not depend exclusively on singing for their livelihood. All answered online questionnaires through Google Forms ®. Sociodemographic and vocal characteristics were investigated before and during the pandemic; symptoms of vocal fatigue were assessed through the vocal fatigue index (VFI); and self-perception of use of singing voice through the evaluation of the ability to sing easily protocol for Brazil (EASE-Br). RESULTS In the comparison between groups, the PSG presented higher scores of vocal fatigue in fatigue and vocal limitation (P = 0.045), vocal restriction (P = 0.002), and recovery with vocal rest (P = 0.008) domains than did the ASG. There was no difference between the groups regarding the use of singing voice. Based on the relationship between self-perception and vocal use characteristics during the pandemic, it was observed that the presence of vocal complaint was the only factor associated with self-perception of fatigue symptomatology in both groups. Regarding the self-perception of the current status of the singing voice, singing time, the presence of vocal complaints, the need to increase visual concentration, and the perception of vocal worsening during the pandemic were considered predictive for amateur singers. For professional singers, vocal complaints and vocal training were predictors for self-perception of the current status of the singing voice. CONCLUSION Professional singers presented with higher scores of vocal fatigue than did amateur singers. The symptomatology of vocal fatigue was associated with the presence of vocal complaints in both groups. However, self-perception of the current status of the singing voice was different between the groups and was associated with vocal training for professional singers and characteristics of vocal demand of singing voice during the pandemic period for amateur singers.

Abstract
INTRODUCTION Vibrato is an oscillation in frequency, intensity, and timbre of the singing voice. Previous studies have found a relationship between its periodicity and perceived quality. The diversity of vibrato enriches the music and singer's performances but create challenges for quantifying and capturing the characteristics that contribute to achieving these expressive goals. Vibrato tones have been addressed using rate, extent, jitter, and shimmer; however, these do not necessarily capture relevant complex time-varying features. This paper applies techniques from disciplines that specialize in periodicity and complexity to provide insight into vibrato characteristics not yet understood. OBJECTIVES This study aimed to assess whether nonlinear metrics are relevant features in characterizing and illustrating differences in vibrato behavior in opera and jazz singing, as well as considering the relationship of nonlinear metrics to other vibrato parameters. METHODS Vibrato tones from published music material of world-class singers from opera and jazz were analyzed with entropy, recurrence, and the established parameters of rate, extent, jitter, and shimmer. Dimensionality reduction was employed to consider the relationship and significance of each of the metrics in collectively characterizing vibrato. RESULTS The principal component, explaining 40% of variability, had positive weights of determinism and line length derived from recurrence while having negative weights of rate, shimmer, and sample entropy. Using these components, the vibrato tones from opera compared to jazz singing were found to be more regular and had lower rate and extent, and it was possible to spotlight singers and notes with high periodicity. CONCLUSION Our study shows that nonlinear metrics applied to vibrato tones provide a valuable tool for observing and quantifying regularity in vibrato tones. The results of this study highlight the potential for more detailed descriptions of vibrato characteristics that may support categorization of individuals, genres, or musical expression in the future and could be applicable to pedagogical techniques.

Abstract
OBJECTIVES/HYPOTHESIS Professional voice users of any age are often concerned about nodules, particularly in pediatric singers. However, an accurate diagnosis allows formulation of an optimal management plan and a successful continuation of these young patients' careers. There is very little literature regarding pediatric professional singers; we aimed to share our experience of over a decade of referrals to our tertiary pediatric voice clinic. STUDY DESIGN This was a retrospective review. METHODS A retrospective review was undertaken of all consecutive patients aged 0-18 years who self-identified as professional voice users and attended our tertiary pediatric voice clinic between December 2010 and December 2021. We analyzed demographics, professional singing status, diagnosis, management, and clinical voice scores. The patients were subdivided into those aged 0-9, 10-16, and 17-18 years. RESULTS A total of 113 pediatric professional voice users attended the tertiary voice clinic in the study period. The commonest self-reported voice use was as a singer. Within the 0-9 years age group, there was a strong male predominance (22 males and three females) and mostly organic (52%) causes. For ages 10-16 years, there was a noted female predominance (15 males and 29 females). In the 17-18 years age group, there was a strong female predominance (10 males and 34 females), with predominantly functional diagnoses (48%). Of significance, only five of the 113 patients had nodules (4.4%). CONCLUSIONS We present a large data set of pediatric professional voice users and demonstrate the numerous underlying diagnoses for their dysphonia, particularly functional disorders. Our experience highlights the need for adequate vocal training for pediatric professional voice users and the need for a multidisciplinary diagnostic and management approach.

Abstract
OBJECTIVE To investigate singers' vocal load by documenting three types of vocal doses (time, cycle, and distance doses) and sound pressure levels during the four phases of rehearsal and how the vocal doses vary between singers across rehearsals in the musical Nine, written by Maury Yeston. METHODS/DESIGN Five student-singers participating in the musical Nine gave informed consent to participate in the study. All five participants were assigned female at birth and female-identifying individuals. They attached a KayPENTAX APM 3300 dosimeter sensor to their lower neck and wore the accelerometer during four three-hour rehearsals throughout the rehearsal process (the music learning phase, the choreography learning phase, the blocking learning phase, and the dress rehearsal) of the musical. The dosimeter records neck vibrations at a rate of 20 samples per second. but it does not record linguistic content. RESULTS A dosimetric analysis of five student singers identified variability in voice production throughout the rehearsal process. According to the dosimetry findings, singers employed extensive low-frequency voicing below the first passaggio, with belting and mixed vocal strategies as the predominant stylistic choices when performing in Nine. Additionally, the singers used an occasional head voice effect at specific moments. The roles of Carla, Saraghina, La Fleur, and Ensemble One and Two required specific vocal ranges due to the musical score. CONCLUSIONS Researchers have yet to establish a safe baseline vocal dose for singers. The vocal dose is affected by many factors, such as duration of phonation, frequency range, SPL, and styles of vocalism required by the score. Louder and heavier vocalization produces larger distance doses, representing the cumulative load placed on vibrating tissue. The cycle dose, distance dose, and SPL reported in this study varied within and between singers. The phonation density graphs show this variability and the low tessitura required by the score. Time doses ranged from 4% to 7% of rehearsal time; this short dose suggests that the rehearsals provided healthy conditions for the successful rehearsal process with efficient attention to the vocalization of a score that requires heavy vocal styles, including belting. While the rehearsal pace was not alarming, the demands of the score alone may prove to be much greater than the vocal dose reported through the rehearsal. Further studies are needed to establish the overall dose of each Broadway role to serve as parameters for vocal pacing and voice care.

Abstract
OBJECTIVE To analyze and compare cepstral measurements in singing and non-singing men and women to understand if vocal adaptations of singers reflect greater cepstral measurement results. METHOD The study included 91 vocally healthy individuals, consisting of 60 erudite or popular singers (30 males, 30 females) and 31 non-singers (16 males, 15 females). The Cepstral Peak Prominence (CPP) and Cepstral Peak Prominence-Smoothed (CPPS) measures were carried out using the sustained /a/ vowel recorded with a unidirectional condenser microphone associated with a sound card on the computer. The Praat software (version 6.1.16) was used to extract the CPP and CPPS measurements. The intra and intergroup values obtained for each sex were compared using the t-test with a 5% significance level. RESULTS There was a CPP (P = 0,000) and CPPS (P = 0,000 and P = 0,001) value difference between the sexes in both groups. Cepstral measurements showed no statistically significant difference between singing and non-singing participants (male: P = 0,778 and P = 0,622; female: P = 0,622 and P = 0,460). CONCLUSION Men presented higher CPP and CPPS values than women, which may be related to the presence of the physiological posterior glottic cleft in women. The knowledge of the cepstral values of singers shows that singing specificities may not reflect in all vocal evaluations.

Abstract
BACKGROUND This original, qualitative study examines the ways in which the concept of respite is expressed and experienced through the activity of singing in refugee mothers, new and expectant, in a perinatal healthcare setting in Logan, Queensland. METHODS Data were collected using a multi-method approach using field notes, yarning circles, and semi-structured interviews. Reflexive Thematic Analysis (TA) yielded themes influenced also by literature on singing, wellbeing, health inequities, and the conceptual lens of respite. RESULTS The research found that singing afforded respite for mothers across four dimensions, allowing for safe spaces, me time, new direction, and immersion. Respite and singing are identified here as strength-based and cultural solutions to wellbeing. No negative effects were reported. CONCLUSIONS The article discusses implications for socially-mediated healthcare in culturally diverse contexts. The idea of "song" enables access to a space of sanctuary wherein health inequities can be tackled in meaningful and decolonising ways.

Abstract
A growing body of research shows that the universal capacity for music perception and production emerges early in development. Possibly building on this predisposition, caregivers around the world often communicate with infants using songs or speech entailing song-like characteristics. This suggests that music might be one of the earliest developing and most accessible forms of interpersonal communication, providing a platform for studying early communicative behavior. However, little research has examined music in truly communicative contexts. The current work aims to facilitate the development of experimental approaches that rely on dynamic and naturalistic social interactions. We first review two longstanding lines of research that examine musical interactions by focusing either on the caregiver or the infant. These include defining the acoustic and non-acoustic features that characterize infant-directed (ID) music, as well as behavioral and neurophysiological research examining infants' processing of musical timing and pitch. Next, we review recent studies looking at early musical interactions holistically. This research focuses on how caregivers and infants interact using music to achieve co-regulation, mutual engagement, and increase affiliation and prosocial behavior. We conclude by discussing methodological, technological, and analytical advances that might empower a comprehensive study of musical communication in early childhood.

Abstract
BACKGROUND This paper explores the mental health and wellbeing outcomes of a massed community choir program in Australia. METHODS This study employed a mixed methods approach. Data were collected via a survey of choir participants (N = 305), four qualitative interviews and focus groups with facilitators and participants (N = 22), and two workshops with organising staff (N = 5). Questions were derived from a co-designed program logic, and data were triangulated and analysed thematically. RESULTS Participants reported feeling a sense of connectedness (psychological), but also experiencing connection (social) with their fellow singers. Psychological outcomes included the sensations of affect, arousal, and affirmation. Social outcomes included experiencing belonging, inclusion, and sharing. These positive psycho-social experiences promoted positive mental health and wellbeing outcomes in the large group of participating singers. CONCLUSIONS This paper addresses gaps in our understanding about the mental health and wellbeing outcomes fostered by community choirs at scale.

Abstract
This action research study explored the co-design of a person-centered caregiver singing (PCCS) protocol and caregivers' experiences of applying the PCCS intervention with people living with dementia. Eight caregivers across two care homes participated in four iterative cycles aimed at refining the training. Qualitative data collected from semi-structed group interviews, individual interactions and researcher reflections were analysed via thematic analysis which informed the refinements to the training protocol. A Person-Centered Caregiver Singing Model was developed from the thematic findings relating to caregivers' experiences of applying the PCCS intervention: enhanced caregiver capabilities, resident's wellbeing, improved relationship, the positive ecological shift, and ease of caregiving. PCCS fostered caregivers' empathy and self-efficacy, helping them better attune to and meet the needs of people with dementia. Findings suggest music therapists could share music therapy-informed skills with caregivers for use in daily care. Further research would be beneficial to understand the relationship between live music interventions and caregivers' self-efficacy and empathy, and to explore the training barriers in South Africa.

Abstract
OBJECTIVE This study examined velopharyngeal (VP) timing characteristics during singing and speaking tasks among singers with varying degrees of classical training. METHODS Pressure-flow data were collected when eight soprano singers sang and spoke the phrase, "I will say hamper," at different pitch (C4 and C5) and loudness levels (soft, medium, and loud). VP aerodynamic variables (VP gap, peak nasal airflow [NF], and peak intraoral pressure [OP]) and timing variables (NF pulse duration, OP pulse duration, and total duration of the /mp/ sequence) were of particular interest. RESULTS Results of linear mixed-effects models showed no significant main effect of task type (speaking vs. singing) on VP aerodynamic variables. Task type was found to have a statistically significant main effect on OP pulse duration (F(1, 77) = 27.590, P < 0.05) and total duration of the /mp/ sequence (F(1, 75.034) = 17.895, P < 0.05), with both durational measures significantly shorter for singing (OP pulse duration: 200 ms, total duration of the /mp/ sequence: 212 ms) than for speaking (OP pulse duration: 228 ms, total duration of the /mp/ sequence: 238 ms). The pitch had a significant main effect on OP pulse duration, with C5 (207 ms) significantly shorter than C4 (221 ms). Loudness was found to have no significant main effects on any of the VP timing variables. CONCLUSIONS VP timing patterns significantly differed between the singing and the speaking task. Specifically, the singers employed a quick OP pulse rise time, which shortened OP pulse duration as well as the total duration of the /mp/ sequence during the singing task in comparison to the speaking task. Robust VP timing patterns observed during singing may reflect the singers' skilled control of the VP mechanism to achieve functional and esthetic goals.

Abstract
OBJECTIVES The phenomenon of vocal fatigue and the types of patients that are at greatest risk for vocal fatigue are not fully understood. The goal was to investigate patient profiles such as voice disorder type, demographics (age and gender), singing identity, interoceptive awareness, and psychosocial impacts on the severity of vocal fatigue. STUDY DESIGN Prospective cohort study. METHODS Ninety-five subjects with voice disorders were asked to complete Part 1 of the Vocal Fatigue Index (VFI-Part1), the Voice Handicap Index-10 (VHI-10), and the Multidimensional Assessment of Interoceptive Awareness, version 2 (MAIA-2). The effects of voice disorder type (structural, neurological, functional), psychosocial impact, age, gender, self-reported singing identity, and interoceptive awareness on self-perceived vocal fatigue (VFI-Part1) were determined using multivariate linear regression. RESULTS Vocal fatigue had a significant psychosocial impact on patients with voice disorders, as measured by the VHI-10 (P < 0.001). However, there were no significant effects of vocal fatigue across any of the three voice disorder types (P's >0.05). Age (P = 0.220), gender (P = 0.430), and self-identified singing experience (P = 0.360) also did not have significant effects on vocal fatigue. Additionally, there were no significant relationships between interoceptive awareness MAIA-2 sum scores (P = 0.056) or any of the MAIA-2 sub-scores (P's > 0.05) and vocal fatigue severity (VFI-Part1). CONCLUSION Vocal fatigue has a significant psychosocial impact on patients with voice disorders. However, patient profiles, including voice disorder type, patient age, gender, singing identity, and level of interoceptive awareness do not appear to play a major role in vocal fatigue symptom reporting. These findings suggest caution should be exercised when attributing patient profiles to vocal fatigue presentation and severity. Studying pathophysiological mechanisms underlying vocal fatigue may help better distinguish unconscious bias in patient profiling from the etiology and severity of vocal fatigue.

Abstract
PURPOSE To evaluate stomatognathic system's structures and functions in classical singers, relating them to the auditory-perceptual judgment of voice quality and voice self-perception. METHODS A cross-sectional pilot study was conducted to evaluate the Stomatognathic System (SS) using orofacial myofunctional evaluation (MBGR Protocol). Voice handicap self-perception was assessed by the Classical Singing Handicap Index (CSHI) and the Voice Handicap Index (VHI-10). Voice samples, recorded according to the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) protocol, underwent auditory-perceptual judgment by two voice experts. All statistical analyses adopted a 5% significance level. RESULTS The study included 15 classical singers (nine women and six men). Adequate assessments of lip and tongue functionality and mobility, upper and lower lip, mentum, and tongue tone were higher compared with altered assessments (P < 0.001). Nasal and oronasal breathing showed similar proportions among singers (P = 0.273). Participants reported greater pain in the masseter muscle (P ≤ 0.001), temporomandibular joint (TMJ) (P ≤ 0.001), and sternocleidomastoid muscle (SCM), especially on the left side (P ≤ 0.001). MBGR score showed no association with singers' voice handicap and voice quality self-perception. CONCLUSION MBGR-evaluated SS items were not related to auditory-perceptual judgment of voice quality and voice self-perception. Singers reported more pain with palpation in the SCM, masseter muscle, and TMJ. Preference for a chewing side was higher than bilateral chewing. Assessing SS is paramount for the multidimensional evaluation of classical singers' voice.

Abstract
OBJECTIVE The COVID-19 pandemic in Brazil affected the lives of singers, with negative impacts of the disease on the voice, such as dysphonia and throat clearing. This study aims to evaluate the presence of dysphonia and throat clearing in singers during the COVID-19 pandemic in Brazil. MATERIAL AND METHODS This is a cross-sectional analytical study with a sample of 154 singers from all over Brazil. Data collection was carried out online, by completing the questionnaire created by the researcher using Google Forms. The following were considered the outcome variables: voice impairment and throat clearing. The bivariate analysis was performed to test the relationship between COVID-19 infection and voice impairment, COVID-19 infection and throat clearing, COVID-19 infection and laryngeal complaints (voice impairment and throat clearing). RESULTS In this study, the mean age of the singers was 35.8 (Standard deviation = ±10.2 years) and 59.2% were female. Most of them worked as professional singers (81.1%) and had more than 10 years of professional experience (57.4%), mainly singing pop music (85.4%). A total of 62% reported vocal alterations during the COVID-19 infection and 53% had vocal alterations after the infection, with 44.0% reporting the onset of throat clearing after the infection. There was a significant association between COVID-19 infection and having voice impairment (P = 0.03; prevalence ratio - PR: 2.33; CI: 1.04-5.46). An association was observed between the onset of throat clearing and the occurrence of COVID-19 infection (P = 0.001; PR: 9.13; CI: 2.47-64.42). CONCLUSIONS The results indicated that there is an association between COVID-19 infection and complaints of dysphonia and throat clearing in Brazilian singers. This study demonstrates the importance of guidance to singers infected with COVID-19 by health voice processionals.

Abstract
OBJECTIVES/HYPOTHESIS Vibrato is a core aesthetic element in singing. It varies considerably by both genre and era. Though studied extensively in Western classical singing over the years, there is a dearth of studies on vibrato in contemporary commercial music. In addressing this research gap, the objective of this study was to find and investigate common crossover song material from the opera, operetta, and Schlager singing styles from the historical early 20th to the contemporary 21st century epochs. STUDY DESIGN/METHODS A total of 51 commercial recordings of two songs, "Es muss was Wunderbares sein" by Ralph Benatzky, and "Die ganze Welt ist himmelblau" by Robert Stolz, from "The White Horse Inn" ("Im weißen Rößl") were collected from opera, operetta, and Schlager singers. Each sample was annotated using Praat and analyzed in a custom Matlab- and Python-based algorithmic approach of singing voice separation and sine wave fitting novel to vibrato research. RESULTS With respect to vibrato rate and extent, the three most notable findings were that (1) fo and vibrato were inherently connected; (2) Schlager, as a historical aesthetic category, has unique vibrato characteristics, with higher overall rate and lower overall extent; and (3) fo and vibrato extent varied over time based on the historical or contemporary recording year for each genre. CONCLUSIONS Though these results should be interpreted with caution due to the limited sample size, conducting such acoustical analysis is relevant for voice pedagogy. This study sheds light on the complexity of vocal vibrato production physiology and acoustics while providing insight into various aesthetic choices when performing music of different genres and stylistic time periods. In the age of crossover singing training and commercially available recordings, this investigation reveals important distinctions regarding vocal vibrato across genres and eras that bear beneficial implications for singers and teachers of singing.

Abstract
Various authors have argued that belting is to be produced by "speech-like" sounds, with the first and second supraglottic vocal tract resonances (fR1 and fR2) at frequencies of the vowels determined by the lyrics to be sung. Acoustically, the hallmark of belting has been identified as a dominant second harmonic, possibly enhanced by first resonance tuning (fR1≈2fo). It is not clear how both these concepts - (a) phonating with "speech-like," unmodified vowels; and (b) producing a belting sound with a dominant second harmonic, typically enhanced by fR1 - can be upheld when singing across a singer's entire musical pitch range. For instance, anecdotal reports from pedagogues suggest that vowels with a low fR1, such as [i] or [u], might have to be modified considerably (by raising fR1) in order to phonate at higher pitches. These issues were systematically addressed in silico with respect to treble singing, using a linear source-filter voice production model. The dominant harmonic of the radiated spectrum was assessed in 12987 simulations, covering a parameter space of 37 fundamental frequencies (fo) across the musical pitch range from C3 to C6; 27 voice source spectral slope settings from -4 to -30 dB/octave; computed for 13 different IPA vowels. The results suggest that, for most unmodified vowels, the stereotypical belting sound characteristics with a dominant second harmonic can only be produced over a pitch range of about a musical fifth, centered at fo≈0.5fR1. In the [ɔ] and [ɑ] vowels, that range is extended to an octave, supported by a low second resonance. Data aggregation - considering the relative prevalence of vowels in American English - suggests that, historically, belting with fR1≈2fo was derived from speech, and that songs with an extended musical pitch range likely demand considerable vowel modification. We thus argue that - on acoustical grounds - the pedagogical commandment for belting with unmodified, "speech-like" vowels can not always be fulfilled.

Abstract
OBJECTIVES/HYPOTHESIS To prospectively establish a normative value for the validated Singing Voice Handicap Index-10 (SVHI-10) patient reported outcome measure (PROM). STUDY DESIGN Prospective cross-sectional study. METHODS Adult singers without voice complaints were prospectively invited to complete a demographics questionnaire followed by the SVHI-10. Participants were excluded if they had sought medical care for voice changes within the last year or currently had throat problems. Statistical analysis was completed to establish a normative value and the distribution of demographics by singing experience, primary genre, and gender. RESULTS One hundred forty-nine healthy participants from diverse backgrounds (including singing, financial, educational, and geographic location) successfully completed the SVHI-10. The mean (SD) score of this cohort was 9.13 (5.15). We defined a normative value as two standard deviations above the mean: 19.43 There was no difference in SVHI-10 score in different age groups. CONCLUSIONS A normative value for the SVHI-10 questionnaire has been missing from the current literature and will be of great utility both in clinical practice and research. In previous research, singers have been shown to be more perceptive to quality change in their singing voices, which may be why the normative score is higher than one may expect. A SVHI-10 score ≥20 should be considered abnormal.

Abstract
OBJECTIVE To investigate the extent to which vocal load is associated with previous diagnosis of a vocal pathology among four major genres of singers (primarily classical, primarily musical theatre (MT), classical and MT combined, and contemporary commercial music only). STUDY DESIGN Cross sectional survey. METHODS/DESIGN An anonymous online survey was sent out to about 1000 professional singers through convenience sampling to touring companies, opera companies, MT companies, agents, directors and musical directors. Social media and email were used to solicit participation in the study. We utilized means and standard deviations for continuous characteristics and frequencies and percentages for categorical characteristics and calculated P values to assess whether differences were statistically significant. RESULTS A total of 396 professional singers completed the survey, yielding a 40% response rate. Nonprofessional singers, incomplete surveys, and respondents <18 years old were excluded, resulting in a total of 238 responses. Among the 238 participants, 32% were performing in the classical style primarily, 33% in the MTstyle primarily, 15% in both classical and MT, and 20% in other contemporary styles only. Mean age was highest among CV + MT and lowest among primarily MT. Combined classical/MT singers were most likely to have a career outside of vocal performance and continue to work in that career followed by other contemporary styles, classical and MT (P = 0.02). Participants in the combined classical/MT group were most likely to have a reported history of vocal pathology followed by classical, other contemporary styles and MT (not statistically significant). However, participants in the contemporary styles were most likely to have a history of more than one type of vocal pathology. Mean vocal load was highest for the MT group. Other nonsinging factors proved significant such as allergy, hydration and acid reflux. Symptoms of allergies were found to be significant across singing genres. A possible reverse causality association was identified in regards to water intake. Participants with acid reflux were three times more likely to have ever reported vocal pathology. CONCLUSION Vocal load was not significantly associated with vocal pathology across singing genres; however other nonsinging factors such as allergy, reflux and water intake were significantly associated with vocal pathology.

Abstract
OBJECTIVE/HYPOTHESIS This study aimed to determine objective production differences relative to two emotional interpretations in performing an excerpt from a classical art song. The null hypothesis was proposed. METHODS The first author recorded an excerpt from an art song. The excerpt was sung with two contrasting musical interpretations: an "empathetic legato" approach, and a "sarcastic" approach characterized by emphatic attacks. Microphone, airflow, and electroglottography signals were digitized. The vowels were analyzed in terms of intensity, long term average spectra, fundamental frequency (fo), airflow vibrato rate and extent, vowel onset slope, intensity comparison of harmonic frequencies, and glottal measures based on electroglottograph waveforms. Four consonant tokens were analyzed relative to airflow, voice onset time, and production duration. RESULTS & CONCLUSIONS The emphatic performance had faster vowel onset, increased glottal adduction, increased intensity of harmonics in 2-3 kHz, increased intensity in the fourth and fifth formants, inferred subglottal pressure increase, increased airflow for /f/, and greater aspiration airflow for /p, t/. Vibrato extents for intensity, fo, and airflow were wider in the emphatic approach. Findings revealed larger EGGW25 and peak-to-peak amplitude values of the electroglottography waveform, suggesting greater vocal fold contact area and longer glottal closure for the emphatic approach. Long-term average spectrum analyses of the entire production displayed minor variation across all formant frequencies, suggesting an insignificant change in vocal tract shaping between the two approaches. This single-case objective study emphasizes the reality of physiological, aerodynamic, and acoustic production differences in the interpretive and pedagogical aspects of art song performance.

Abstract
INTRODUCTION The present study aimed to develop a new tool for the evaluation of singers with self-reported symptoms suggestive of laryngopharyngeal reflux (LPR) (the SVHI-12-LPR), by correlating RSI with SVHI in a population sample of 163 subjects (both professional and amateur singers), evaluated also by videolaryngostroboscopy. This study was a cross-sectional, double-observational study. METHODS RSI and SVHI were administered to 159 singers (amateurs, singing students, and professional singers). All subjects underwent videolaryngostroboscopy to objectively identify four subgroups: normal subjects (41.5%), subjects with organic lesions occupying the glottic space (17.6%), subjects with functional dysphonia (18.2%), and subjects presenting solely signs suggestive of LPR (22.6%). Using the validated RSI threshold, 33.9% of participants presented an RSI total score >13, suggestive of LPR. RESULTS Subjects with a suspected diagnosis of LPR at videolaryngostroboscopy presented a mean RSI significantly higher than other subgroups (p < 0.001). Moreover, the SVHI-36 score did not statistically differ between pathological subgroups. A significant positive relationship was observed between RSI and SVHI total score (Spearman's rank correlation coefficient [ρ] = 0.474, p < 0.001). 12 SVHI items (items 1, 2, 4, 5, 6, 7, 12, 20, 24, 25, 26, 30) showed a significant association with RSI pathology classification. Statistical analysis demonstrated for the 12 selected items (SVHI-12-LPR) acceptable specificity (0.691) and sensibility (0.833) for the suspected diagnosis of LPR with a cut-off of 15. CONCLUSIONS From the SVHI-36, 12 items were extracted that correlated with the specific impact that LPR has on the singer's voice (SVHI-12-LPR), as evaluated by RSI and videolaryngostroboscopy. Such questionnaire represents a new tool that could be applied to singers with symptoms suggestive of LPR to select which patients would benefit from a further phoniatric and videolaryngostroboscopic evaluation.

Abstract
The COVID-19 pandemic has led to restrictions such as social distancing and mandatory wearing of face masks. Singing and religious gatherings have been linked to infection clusters, and between 2020 and 2021 indoor congregational singing and chanting were prohibited in the United Kingdom. We evaluated attitudes to face mask use and their acceptability as well as changes within places of worship since their reopening in July up to autumn 2020. In this cross-sectional study, participants were recruited using convenience sampling through selective targeting of religious organisations and social media. Participants self-enrolled and completed an online questionnaire, which included open and closed questions. We used multivariable logistic regression to identify factors associated with face mask acceptability. We performed thematic analysis to evaluate responses to open questions. A total of 939 participants were included in the analysis. Median age was 52.7 years and 66.1% were female, while 80.7% identified as Christian. A majority (672/861; 78.0%) of participants would find it acceptable to wear a face mask and reduce their singing or chanting volume if required, even though 428/681 (49.1%) found face masks to be uncomfortable. Multivariable regression found that younger age was associated with a higher acceptability of face masks (adjusted OR (aOR): 0.98 (95% confidence interval (95% CI) 0.96-1.00), p = 0.0218). The majority of respondents stated that religious services had become shorter, attended by fewer people and with reduced singing or chanting. Most (869/893, 97.3%) stated their place of worship complied with government guidelines, with 803/887 (90.5%) reported that their place of worship enforced face mask wearing and 793/887 (89.4%) at least moderately happy with precaution measures. Our study demonstrates the significant impact of COVID-19 in places of worship but a high degree of compliance with guidelines. Face masks, despite practical difficulties, appeared to be more acceptable if there was an incentive of being able to sing and chant.

Abstract
OBJECTIVES Pitch perception distortion (PPD) is a novel term describing a phenomenon in which an amplified, accompanied singer's perception of their sung pitch relative to band or accompaniment becomes ambiguous, leading to one of two conditions: a) the singer believes they are out of tune with the accompaniment, but are in tune as perceived by a listener, or b) the singer believes they are in tune with the accompaniment, but are not. This pilot study aims to investigate the existence and incidence of PPD among amplified, accompanied performers and identify associated variables. DESIGN/METHODS 115 singers were recruited to participate in an online survey, which collected information on musical training, performance environment, and PPD experience. RESULTS Reported PPD incidence was 68%, with 92% of respondents indicating that PPD occurred rarely. The factors reported as most associated with PPD experiences included loud stage volume, poor song familiarity, singing outside one's habitual pitch range, and singing loudly. Contrary to previous studies and our hypotheses, no association was found between modality of auditory feedback (e.g., in-ears versus floor monitors) and incidence of PPD. Additionally, higher levels of training were found to be associated with higher incidence of PPD. CONCLUSIONS The reported incidence supports that PPD exists beyond chance and anecdotal experience. In light of the highly trained sample, the data suggest that pitch accuracy in accompanied, amplified performance may be more associated with aural environment-specifically loud stage volume-and a highly trained singer's tuning strategy in response to that environment rather than a singer's mastery of vocal intonation skills in isolation. Loud stage volume was implicated as a primary factor associated with PPD, which may be related to the stapedius reflex. Future investigations will target attempted elicitation of PPD in trained singers after establishing baseline auditory reflex thresholds and objective measurements of intonation accuracy.

Abstract
OBJECTIVES Parkinson's disease (PD) is a neurodegenerative disease leading to motor impairments and dystonia across diverse muscle groups including vocal muscles. The vocal production challenges associated with PD have received considerably less research attention than the primary gross motor symptoms of the disease despite having a substantial effect on quality of life. Increasingly, people living with PD are discovering group singing as an asset-based approach to community building that is purported to strengthen vocal muscles and improve vocal quality. STUDY DESIGN/METHODS The present study investigated the impact of community choir on vocal production in people living with PD across two sites. Prior to and immediately following a 12-week community choir at each site, vocal testing included a range of vocal-acoustic measures, including lowest and highest achievable pitch, duration of phonation, loudness, jitter, and shimmer. RESULTS Results showed that group singing significantly improved some, though not all, measures of vocal production. Group singing improved lowest pitch (both groups), duration (both groups), intensity (one group), and jitter (one group) and shimmer (both groups). CONCLUSIONS These findings support community choir as a feasible and scalable complementary approach to managing vocal production challenges associated with PD.

Abstract
The notion that lifestyle factors, such as music-making activities, can affect cognitive functioning and reduce cognitive decline in aging is often referred to as the mental exercise hypothesis. One ubiquitous musical activity is choir singing. Like other musical activities, singing is hypothesized to impact cognitive and especially executive functions. Despite the commonness of choir singing, little is known about the extent to which singing can affect cognition in adulthood. In this cross-sectional group study, we examined the relationship between age and four auditory executive functions to test hypotheses about the relationship between the level of mental activity and cognitive functioning. We also examined pitch discrimination capabilities. A non-probabilistic sample of 147 cognitively healthy adults was recruited, which included 75 non-singers (mean age 52.5 ± 20.3; 20-98 years) and 72 singers (mean age 55.5 ± 19.2; 21-87 years). Tests of selective attention, processing speed, inhibitory control, and working memory were administered to all participants. Our main hypothesis was that executive functions and age would be negatively correlated, and that this relationship would be stronger in non-singers than singers, consistent with the differential preservation hypothesis. The alternative hypothesis - preserved differentiation - predicts that the difference between singers and non-singers in executive functions is unaffected by age. Our results reveal a detrimental effect of age on processing speed, selective attention, inhibitory control and working memory. The effect of singing was comparatively more limited, being positively associated only with frequency discrimination, processing speed, and, to some extent, inhibitory control. Evidence of differential preservation was limited to processing speed. We also found a circumscribed positive impact of age of onset and a negative impact of singing experience on cognitive functioning in singers. Together, these findings were interpreted as reflecting an age-related decline in executive function in cognitively healthy adults, with specific and limited positive impacts of singing, consistent with the preserved differentiation hypothesis, but not with the differential preservation hypothesis.

Abstract
OBJECTIVES Over time, papers or reports may come to be taken for granted as evidence for some phenomenon. Researchers cite them without critically re-examining findings in the light of subsequent work. This can give rise to misleading or erroneous results and conclusions. We explore whether this has occurred in the widely reported outbreak of SARS-CoV-2 at a rehearsal of the Skagit Valley Chorale in March 2020, where it was assumed, and subsequently asserted uncritically, that the outbreak was due to a single infected person. STUDY DESIGN Review of original report and subsequent modelling and interpretations. METHODS We reviewed and analysed original outbreak data in relation to published data on incubation period, subsequent modelling drawing on the data, and interpretations of transmission characteristics of this incident. RESULTS We show it is vanishingly unlikely that this was a single point source outbreak as has been widely claimed and on which modelling has been based. CONCLUSION An unexamined assumption has led to erroneous policy conclusions about the risks of singing, and indoor spaces more generally, and the benefits of increased levels of ventilation. Although never publicly identified, one individual bears the moral burden of knowing what health outcomes have been attributed to their actions. We call for these claims to be re-examined and for greater ethical responsibility in the assumption of a point source in outbreak investigations.

Abstract
INTRODUCTION Arguably one of the most controversial features of the singing voice, especially in a choral context, is the phenomenon of vibrato. Numerous pedagogical articles, mostly written by experienced choral singers or directors, discuss the importance of vibrato, sharing anecdotal insights about its control (often advocating reduction) in choral blend and vocal health. OBJECTIVES This systematic review aims to identify the main questions posed in the empirical study of vibrato during group singing, and how they have been addressed to date through empirical investigations. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analyses was employed for this review. The review team consisted of the two authors. A data extraction form was designed to capture information about the participants (including age, gender, music and singing experience), study methods, experimental procedures, outcome measures, and statistical findings. RESULTS Seventeen studies were included in the review and revealed that (a) relatively few empirical investigations have studied vibrato in vocal ensembles; (b) the majority focused on vibrato production rather than perception; (c) methodological approaches include Synthesis, Multi-track recordings, Stereo/Binaural recordings, and Lx/Contact recordings; and (d) the studies focused on the main themes of Adjustment, Identification, Interaction, Intonation, and Style. CONCLUSION With the current body of literature, it is not possible to draw general conclusions around vibrato behavior during group singing. However, the review highlights the main subareas of interest and valuable methods which have been established and through which future research can collectively shed further light on the role of vibrato in choral singing.

Abstract
Background Chronic obstructive pulmonary disease (COPD) and interstital lung disease (ILD) are incurable conditions characterised by airflow limitation, persisting respiratory symptoms, and progressive respiratory failure. People living with COPD or ILD often suffer from chronic and severe breathlessness, with limited treatment options and low engagement rates with current therapies. Group singing represents a potential community-based therapy to improve quality of life for patients with COPD or ILD and breathlessness. Methods This protocol papers describes SINFONIA, a parallel, double-arm, randomised, blinded-analysis, mixed-methods phase II/III trial of guided, online group singing that will be conducted over 24 months. Adults with confirmed COPD or ILD, on stable treatment for at least four weeks at time of recruitment, with a modified Medical Research Council (mMRC) dyspnoea score of two or greater, who are capable and willing to give consent, and not currently participating in pulmonary rehabilitation will be eligible to participate. Carers may optionally enrol in the trial. Data will be collected on quality of life, anxiety and depression, breathlessness, mastery of breathing, exercise tolerance, loneliness, healthcare utilisation, and carer quality of life (optional). Participants will be randomised 1:1 to intervention or control arms with intervention arm attending one 90 min, guided, online, group singing session per week for 12 weeks and control arm continuing routine care. Phase II of the trial aims to determine the feasibility and acceptability of guided, online group singing and will collect preliminary data on effectiveness. Phase III aims to determine whether guided, online group singing has an effect on quality of life with the primary outcome being a between arm difference in quality of life (36-item Short Form Survey) measured at 12 weeks. Discussion SINFONIA is the first study is the first of its kind in Australia and to our knowledge, the first to deliver the singing intervention program entirely online. Determining the feasibility, acceptability, and effectiveness of guided, online group singing is an important step towards improving low-cost, low-risk, community-based therapeutic options for patients living with COPD or ILD and breathlessness. Trial registration: Phase II—ACTRN12621001274864, registered 20th September 2021; Phase III—ACTRN12621001280897, registered 22nd September 2021.

Abstract
OBJECTIVE To verify possible correlations between formant and cepstral parameters and oropharyngeal geometry in singers, stratified by sex. METHOD Voice records and oropharyngeal measures of 31 singers - 13 females and 18 males, mean age of 28 (±5.0) years - were retrieved from a database and analyzed. The oropharyngeal geometry measures were collected with acoustic pharyngometry, and the voice records consisted of sustained vowel /Ԑ/ phonation, which were exported to Praat software and edited to obtain the formant and cepstral parameters, stratified by sex. The Pearson linear correlation test was applied to relate voice parameters to oropharyngeal geometry, at the 5% significance level; the linear regression test was used to justify the variable related to the second formant. RESULTS Differences between the sexes were identified only in the oral cavity length (greater in males) and pharyngeal cavity length (greater in females). There was a linear correlation between the third formant and the cepstrum in the female group. In the male group, there was a linear correlation between the cepstrum and the third and fourth formants. A positive linear correlation with up to 95% confidence was also identified between the pharyngeal cavity volume and the second formant in the female group, making it possible to estimate a regression model for the second formant (R2 = 0.70). CONCLUSION There are correlations between the oropharyngeal geometry and formant and cepstral parameters in relation to sex. The pharyngeal cavity volume showed the greatest correlation between females and the second formant.

Abstract
OBJECTIVES The Vocal Tract Organ has had a number of iterations resulting from advances in available technology as well as requirements of perceptual experiments and performance paradigms. The objective of this paper is to relate the development history of the Vocal Tract Organ from the original vision to what it is today as a modern version of the Vox Humana pipe organ stop for application in voice production and perception research. STUDY DESIGN Descriptive METHODS/DESIGN: The latest Vocal Tract Organ is a polyphonic eight-channel eight-stop one manual Vocal Tract Organ that enables tab stop selected three-D printed vocal tracts to be used to create sound. This version includes eight stops (four for female vowel oral tracts and four for male vowel oral tracts). The stops are implemented using conventionally engraved pipe organ stop tabs labeled "Vox Humana Female" or "Vox Humana Male" followed by the three-D printed vowel: "EE", "AH", "ER" or "UU." This is described alongside the development stages from which it emerged and covers all previous versions of the Vocal Tract Organ. At the heart of the latest instrument is a Bela BeagleBone Black with a Bela cape audio expander board which incorporates eight 16-bit audio outputs at 44.1 kHz sampling rate (earlier versions based on the Arduino Mega board were limited to 8-bit audio at an audio sampling rate of 16.384 kHz which limited the overall output spectrum). The latest Vocal Tract Organ is programmed using the audio graphical programming language Pure Data which is directly compatible with the Bela system. The Pure Data patch creates eight larynx outputs at the pitches set by the keys depressed on the keyboard and these are routed to Vocal Tract Organ loudspeakers with three-D printed vocal tracts attached. RESULTS The Bela system has enabled real-time synthesis of eight-note polyphonic sounds to eight separate three-D printed vocal tracts, each being selectable via an organ tab stop switch. The instrument has been cased in a purpose-designed and built prototype laser-cut enclosure that incorporates the eight tab stops, a MIDI keyboard input, a pipe organ style swell (volume) pedal connection, four stereo (eight channels) audio amplifiers and terminal connections for the eight loudspeakers. CONCLUSIONS The Vocal Tract Organ functions as a musical instrument for performance and as an instrument for vowel and pitch perception research. Implementing it with the Bela family of processors allows for low audio latency of 1 ms and rapid prototyping due to being able to program directly with the high-level graphical audio programming language, Pure data (Pd).

Abstract
OBJECTIVE The breathing technique is a determining factor for the singer's sound quality and consequently crucial for the choral sound. However, very little is known about possible influences of the conductor's preparatory gesture on the way choral singers inhale before the beginning of a piece (respectively every subsequent phrase). The conducting literature does not discriminate between out- and inward preparatory gestures and even describes them as equivalent, but previous studies suggest that singers assign different types of inhalation to different preparatory gestures. It may therefore be assumed that the type of preparatory gesture has a direct influence on the singer's inhalation and tone production, and the aim of this study is hence to examine possible effects of two contrasting preparatory gestures on the singer's inhalation type and the resulting tone quality. METHODS In our within-subjects study design, 18 healthy choral singers (9 male/ 9 female) were recruited to participate in a laboratory experiment. The participants were asked to sing a tone suitable for their voice register in response to different video stimuli. These consisted of two conducting-videos, each showing a different preparatory gesture, and two control conditions with an animated bar and an arrow indicating the desired breathing type. The singers reacted to 10 sets of videos, each set consisting of the four stimuli in randomized order. For evaluation of the breathing behavior and vocal output during the different experimental conditions, chest wall kinematics of upper rib cage, abdominal rib cage and abdomen were measured via 3D motion capture and voice samples were recorded. The obtained data were filtered and compared using the repeated measures analysis of variance and post hoc Tukey test for significant results. The level of significance was set at P < 0.05. RESULTS The results of the study show significant differences in volume of the abdomen between the two different gestures (F1,17 = 24.04, η2 = 0.59, P = 0.0001), which can be validated by the two control measurements (F1,17 = 21.12, η2 = 0.55, P = 0.0002). An outward preparatory gesture evoked an abdominal breathing type while an inward-upward movement led to an inhalation with a higher portion of clavicular breathing. Furthermore, significant differences in timbre and loudness of the produced tone could be observed. The maximum sound pressure level of the outward preparatory gesture was significantly higher than in case of the inward-upward movement (F1,17 = 20.4, η2 = 0.56, P = 0.0004). CONCLUSIONS In contrast to the existing conducting literature, which does not discriminate between out- and inward preparatory gestures, the results of this study show that the conductor's choice of trajectory direction and form of the preparatory gestures elicit spontaneous, gesture-specific reactions in singers' breathing behavior as well as the corresponding loudness and sound quality.

Abstract
BACKGROUND Postnatal depression (PND) affects 13% of new mothers, with numbers rising during the COVID-19 pandemic. Despite this prevalence, many women have difficulty with or hesitancy towards accessing pharmacological and/or psychological interventions. Group-based mother-baby activities, however, have a good uptake, with singing improving maternal mental health and the mother-infant relationship. The recent lockdowns highlight the importance of adapting activities to an online platform that is wide-reaching and accessible. AIMS The SHAPER-PNDO study will primarily analyse the feasibility of a 6-week online singing intervention, Melodies for Mums (M4M), for mothers with PND who are experiencing barriers to treatment. The secondary aim of the SHAPER-PNDO study will be to analyse the clinical efficacy of the 6-week M4M intervention for symptoms of postnatal depression. METHODS A total of 120 mothers and their babies will be recruited for this single-arm study. All dyads will attend 6 weekly online singing sessions, facilitated by Breathe Arts Health Research. Assessments will be conducted on Zoom at baseline and week 6, with follow-ups at weeks 16 and 32, and will contain interviews for demographics, mental health, and social circumstances, and biological samples will be taken for stress markers. Qualitative interviews will be undertaken to understand the experiences of women attending the sessions and the facilitators delivering them. Finally, data will be collected on recruitment, study uptake and attendance of the programme, participant retention, and acceptability of the intervention. DISCUSSION The SHAPER-PNDO study will focus on the feasibility, alongside the clinical efficacy, of an online delivery of M4M, available to all mothers with PND. We hope to provide a more accessible, effective treatment option for mothers with PND that can be available both during and outside of the pandemic for mothers who would otherwise struggle to attend in-person sessions, as well as to prepare for a subsequent hybrid RCT. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT04857593 . Registered retrospectively on 22 April 2021. The first participants were recruited on 27 January 2021, and the trial is ongoing.

Abstract
OBJECTIVES The study aims to quantify the impact of sociodemographic, personal, and choir-related characteristics on perceived singing well-being and mental health changes due to singing. STUDY DESIGN 847 German adult choristers (233m, 614f, age 18-86 years) were interviewed in a cross-sectional online questionnaire study that included questions on singing well-being, vocal and choral characteristics, the adapted versions of the Bochum change questionnaire (BCQ2000), the Utrecht Work Engagement Scale (UWES-09), and the WHO-5 well-being index. METHODS Multiple regression models were calculated with singing related well-being or mental health changes as dependent variables and individual and choir-related characteristics as factors. Predictors of mental health benefits were analyzed in gender subgroups and in persons with a low or normal/high score on the WHO-5. RESULTS On average, participants rated the impact of singing on well-being and mental health changes positively. Subgroup analysis revealed smaller but significant positive mental health effects in men compared to women and in persons with a low WHO-5 score compared to those with a normal/high score. Education level and relationship status were not significantly related to subjects' perceptions of mental health benefits, whereas singing well-being increased with age in women and in participants with a low WHO-5 score. Larger improvements in mental health came along with longer choir membership, more singing hours per week, and a high engagement in choral activity. Significant positive associations of well-being with optimal singing behavior and vocal warm-ups were observed. CONCLUSION Results suggest that singers of all ages, genders, and educational backgrounds perceive the choral experience as beneficial to their well-being and mental health. Positive effects are related to WHO-5 scores, engagement in choral activity, and optimal singing conditions. On average, women rate singing benefits higher than men and singers with preexisting vocal pathologies or low WHO-5 benefit slightly less.

Abstract
The objective of this study was to verify the immediate effect of the voiced tongue trill technique in ascending and descending glissandos on the voice range profile of choir members. A total of 25 sopranos, mezzo-sopranos, contraltos, tenors, and baritones participated in the study. They were choir members, aged 20 to 45 years, with no voice symptoms, and able to perform the voiced tongue trill technique. Their voice range profile was analyzed before and after performing the ascending and descending technique for 2 and 5 minutes. The maximum fundamental frequency values in the study groups increased after performing the ascending and descending technique for 2 minutes (P = 0.001) and 5 minutes (P = 0.003). The range in Hz increased after 2 minutes (P = 0.010) and 5 minutes (P = 0.050) of the ascending technique and after 2 minutes (P = 0.001) of the descending technique, and the minimum fundamental frequency mean value suffered interference from the type of technique (ascending/descending). The immediate effects of VTTT in glissandos on the VRP of choir members' considering the two factors: condition and time, in ascending and descending glissandos for 2 and 5 minutes increased the maximum frequency and the range in Hz of choristers. Regarding volume levels results, no difference was found in intensity after applying the technique.

Abstract
Pregnancy has profound effects on a variety of body systems by way of hormonal and physical changes. Many of these changes directly affect body systems involved in singing. Assumptions exist about what can happen to a person's voice during pregnancy, but these assumptions are based on theoretical predictions leaving little knowledge of the lived experiences of voice changes during pregnancy. An anonymous mixed-method survey was given to 321 professional singers to gain insights on the lived experiences of pregnant singers. This investigation explored what people were told about the effects of pregnancy on the voice in comparison to what they actually experienced. Results show that about half of the respondents' experience matched what they were told for respiration. For phonation and vocal quality less than 25% respondent's experience matched what they were told. In addition, most of the information respondents received came from friends, colleagues, and teachers compared to medical professionals suggesting a need for more interdisciplinary education to best prepare vocalists who are contemplating becoming pregnant.

Abstract
This study aimed to investigate what are the factors that influence the perception of one's own voice, and if there are any differences using voice between speaking and singing. Further the study purported to examine how these attitudes affect individuals' vocal behavior in personal and social contexts. A total of 100 participants completed the survey which comprised 23 questions about demographics, music experience, speaking voice, and singing voice. The quantitative data were analyzed by correlations and paired t test. For qualitative analyses, content analysis was conducted. The results revealed an even distribution among negative, neutral, and positive attitudes regarding singing and speaking voices and their effects on vocal behavior. For their negative/positive perceptions of their voices, participants referenced factors related to vocal attributes, personal features, social or external validation, emotional quality of the voice, etc. Lastly, result showed that one's perception of the speaking voice has some influence on behaviors ranging from the personal (expressing oneself) to social (interacting with people) aspects. The findings of this study implies that one's attitude toward one's own voice substantially impacts one's personal, interpersonal and social-presentation.

Abstract
Limited evidence has shown that practising musical activities in aging, such as choral singing, could lessen age-related speech perception in noise (SPiN) difficulties. However, the robustness and underlying mechanism of action of this phenomenon remain unclear. In this study, we used surface-based morphometry combined with a moderated mediation analytic approach to examine whether singing-related plasticity in auditory and dorsal speech stream regions is associated with better SPiN capabilities. 36 choral singers and 36 non-singers aged 20-87 years underwent cognitive, auditory, and SPiN assessments. Our results provide important new insights into experience-dependent plasticity by revealing that, under certain conditions of practice, amateur choral singing is associated with age-dependent structural plasticity within auditory and dorsal speech regions, which is associated with better SPiN performance in aging. Specifically, the conditions of practice that were associated with benefits on SPiN included frequent weekly practice at home, several hours of weekly group singing practice, singing in multiple languages, and having received formal singing training. These results suggest that amateur choral singing is associated with improved SPiN through a dual mechanism involving auditory processing and auditory-motor integration and may be dose dependent, with more intense singing associated with greater benefit. Our results, thus, reveal that the relationship between singing practice and SPiN is complex, and underscore the importance of considering singing practice behaviours in understanding the effects of musical activities on the brain-behaviour relationship.

Abstract
OBJECTIVE This study explored the voice experience, singing ability, and wellbeing of singers diagnosed with Hypermobility Spectrum Disorder (HSD) or hypermobile Ehlers-Danlos Syndrome (h-EDS). STUDY DESIGN This was a mixed-method study. A purposive sampling strategy was used. Data were collected via an online survey, using written closed and open-ended questions. METHODS 276 adults completed the survey. This study focuses on a subset of professionally-trained singers (n=71). Responses elicited information about participants' voice health and function, symptoms of hypermobility, singing experiences and training. Data were analysed using template analysis. RESULTS Many participants reported wide vocal ranges and enjoyment of singing but 74.6% of participants across all age groups (18-60 years) experienced voice difficulties. Three common themes were identified: (1) 'My unreliable voice': The ups and downs; (2) Wider effects of HSD/h-EDS on singers, and (3) Need for acknowledgment and support. CONCLUSIONS Voice difficulties and hypermobility-related health conditions affected the participants' abilities to sing and perform; this impacted their professional and personal opportunities, communication, relationships, and wellbeing. Our results indicate that symptoms of voice disorder worsen over time. We suggest practical strategies that singers and training providers could implement to support hypermobile singers. More research is needed to fully understand voice difficulties in singers with HSD/H-EDS and to inform tuition and support.

Abstract
OBJECTIVE The aim of this meta-analysis was to evaluate the evidence on the effectiveness of music therapy in the recovery of language function in post-stroke aphasia, compared with conventional therapy or no therapy. METHODS We searched studies that explored the effect of music therapy on language function in post-stroke aphasia and published in PubMed, Embase, the Cochrane Library, Web of Science, CINAHL, ProQuest Digital Dissertations, and ClinicalTrials.gov from inception to March 2021. Six reviewers independently screened out eligible studies, extracted data, and evaluated the methodological quality. Results were pooled using mean difference (MD) with 95% confidence interval (CI). Heterogeneity was assessed by the chi-square test and I2 statistic. RESULTS Six studies were included in this meta-analysis involving 115 patients. The methodological quality of these studies ranged from poor to excellent. There was significant mean difference in functional communication for post-stroke aphasia by 1.45 (95% CI: 0.24, 2.65; P = 0.02, from poor to excellent evidence), in repetition by 6.49 (95% CI: 0.97, 12.00; P = 0.02, from acceptable to excellent evidence), and in naming by 11.44 (95% CI: 1.63, 21.26; P = 0.02, from acceptable to excellent evidence). But there was no significant difference in comprehension for post-stroke aphasia by 7.21 (95% CI: - 10.88, 25.29; P = 0.43, from acceptable to excellent evidence). CONCLUSIONS Music therapy can improve functional communication, repetition, and naming in patients with post-stroke aphasia, but did not significantly improve comprehension.

Abstract
BACKGROUND Postpartum depression is fairly common in new mothers and moreover associated with impaired bonding and poor maternal well-being. The aim of the present study was to investigate the impact of a mother-infant singing intervention within the first three months after birth on maternal well-being, depressive symptoms and bonding. METHODS 120 women who were recruited at the maternity ward at the University Clinic in Düsseldorf took part in this prospective, randomised-controlled study. Beside the baseline measurement 1-3 days after childbirth, depressive symptoms, maternal well-being and mother-infant bonding were evaluated with questionnaires before (two weeks after birth) and after (twelve weeks after birth) the intervention took place. The experimental group (n = 59) participated in several singing intervention sessions while the control group (n = 61) did not. In the intervention group, salivary cortisol as well as attachment and mood were assessed immediately before and after the singing sessions. RESULTS The participants of the intervention group showed a significant reduction of cortisol (p = .023) and an improvement of attachment and mood from start to end of the intervention session (all p ≤ .008). However, no prolonged effects were revealed beyond the intervention sessions as the two groups did not differ regarding the alterations of the primary outcomes postpartum depression (interaction effect p = .187) and postpartum bonding (interaction effect p = .188) in the 10-week period from two up to twelve weeks after childbirth (all p > .05). Additional analyses of singing habits at home in both groups, revealed that only in the singing group more frequent singing was associated with less anxiety and more well-being of the mother. CONCLUSION Singing towards the infant seems to have positive immediate effects on the well-being of new mothers (on subjective variables as well as physiological measurements). However, the intervention did not lead to more long lasting positive effects although several limitations should be considered.

Abstract
Many everyday tasks share high-level sensory goals but differ in the movements used to accomplish them. One example of this is musical pitch regulation, where the same notes can be produced using the vocal system or a musical instrument controlled by the hands. Cello playing has previously been shown to rely on brain structures within the singing network for performance of single notes, except in areas related to primary motor control, suggesting that the brain networks for auditory feedback processing and sensorimotor integration may be shared (Segado et al. 2018). However, research has shown that singers and cellists alike can continue singing/playing in tune even in the absence of auditory feedback (Chen et al. 2013, Kleber et al. 2013), so different paradigms are required to test feedback monitoring and control mechanisms. In singing, auditory pitch feedback perturbation paradigms have been used to show that singers engage a network of brain regions including anterior cingulate cortex (ACC), anterior insula (aINS), and intraparietal sulcus (IPS) when compensating for altered pitch feedback, and posterior superior temporal gyrus (pSTG) and supramarginal gyrus (SMG) when ignoring it (Zarate et al. 2005, 2008). To determine whether the brain networks for cello playing and singing directly overlap in these sensory-motor integration areas, in the present study expert cellists were asked to compensate for or ignore introduced pitch perturbations when singing/playing during fMRI scanning. We found that cellists were able to sing/play target tones, and compensate for and ignore introduced feedback perturbations equally well. Brain activity overlapped for singing and playing in IPS and SMG when compensating, and pSTG and dPMC when ignoring; differences between singing/playing across all three conditions were most prominent in M1, centered on the relevant motor effectors (hand, larynx). These findings support the hypothesis that pitch regulation during cello playing relies on structures within the singing network and suggests that differences arise primarily at the level of forward motor control.

Abstract
Objectives In the face of the SARS-CoV-2 pandemic, people with dementia and their carers are contending with serious challenges to their health and wellbeing, due to risk of severe illness, limiting of social contact and disruption to usual activities. Many forms of support for people with dementia and their carers, including singing groups, have moved online using videoconferencing. Previous research has demonstrated the benefits of group singing, which include cognitive stimulation, meaningful activity and peer support. However, although we know which aspects of the singing group experience participants find helpful, we do not know how this experience translates into an online videoconferencing format, and this is a very new field with little existing research. This article reviews the literature pertinent to online singing interventions and uses the findings to develop some suggestions for running an online singing group. Study design: Scoping review. Methods Systematic literature searches were conducted in EMBASE, Medline, CINAHL, PsycINFO and Web of Science. Owing to the paucity of existing research, searches were also conducted in Google Scholar. The scope of the review covered five related areas: online music making and music therapy, telemedicine and telecare, everyday technology for people with dementia, digital arts and dementia, and use of technology for social interaction and leisure. Our analysis aimed to integrate the results to inform the implementation of online singing groups for people with dementia. Results Scoping of evidence from discrete fields of enquiry and different disciplinary traditions can inform the delivery of online singing in dementia. This literature also yields useful insights into the role of the carer and how best to support participants to use technology. Barriers and facilitators to online singing were found to relate both to the technology and to the individual participant. Conclusion Lockdown restrictions have led to much innovation, and this is likely to lead to changes in practice even after normal life resumes. The suggestions in this article will be helpful primarily for practitioners moving into online work and researchers investigating this novel area. They may also be useful to commissioners and policymakers because they reflect current knowledge about best practice.

Abstract
OBJECTIVE The evaluation of real-world, hospital-based, arts programmes is important for quality assurance, to increase knowledge of successful practice and awareness of effective arts-health collaborations. The objective of this study was to describe the Music for Wellness programme and evaluation at St John of God Frankston Rehabilitation Hospital, Australia. STUDY DESIGN An impact evaluation and quasi-experimental pre-post study was conducted. METHODS The Music for Wellness programme for rehabilitation patients ran on a weekly basis for 18 weeks (i.e., 18 stand-alone workshops). Evaluation feedback was collected from patients and hospital staff/visitors. The primary outcome measures were pre-post workshop changes in patients' mood, measured via a 'faces' visual analogue scale; and pain, measured via a numerical rating scale. Linear mixed models and growth curve analyses were performed. Evaluation questions about mental well-being, pain reduction, musical skill attainment and the hospital environment were also asked and, a descriptive analysis was conducted. RESULTS Between the baseline, preworkshop and postworkshop time points, a significant increase in rehabilitation patients' mood and decrease in self-reported pain were found. Changes were consistent over time. The patients and hospital staff/visitors agreed the programme enhanced the hospital environment and music skills, resulted in positive benefits (e.g., relaxation, opportunity to socialise) and should be continued. CONCLUSION This study provides valuable information about a low-cost, non-pharmacological programme that successfully enhanced the hospital environment and supported patients' well-being in a rehabilitation setting.
