Análise de cantores de baile em estilo de canto popular e lírico:perceptivo-auditiva, acústica e da configuração laríngea

Abstract

Objetivo: deste estudo foi verificar os ajustes laríngeos realizados por cantores profissionais do gênero popular durante a imitação do canto em estilo lírico uma vez que muitas vezes ao ouvirmos um cantor popular interpretar uma música clássica percebemos que o mesmo faz modificações em sua qualidade vocal, tentando se aproximar, por imitação, do canto lírico. Forma de estudo: Clínico prospectivo. Material e método: Foram analisados 26 cantores profissionais do gênero popular, 10 homens e 16 mulheres, atuantes em baile. Foi aplicado questionário sobre perfil vocal, realizada análise perceptivo-auditiva e acústica das vozes e avaliação nasofibrolaringoscópica para análise da configuração laríngea nos estilos de canto popular e lírico. Resultado: A análise perceptivo-auditiva revelou que, ao cantar um trecho de música em estilo lírico, o cantor popular muda a qualidade vocal, aumentando o vibrato, o volume vocal, melhorando a ressonância vocal e sobrearticulando mais as palavras. Na análise espectrográfica não foi observada a ocorrência do formante do cantor em nenhuma das vozes. O ajuste laríngeo realizado por cantores populares ao imitarem o estilo de canto lírico foi predominantemente o aumento das constrições ântero-posterior e mediana sendo que a constrição mediana ocorreu mais no sexo masculino. Os valores de jitter e shimmer reduziram significantemente na vogal cantada em relação à vogal falada nas vozes femininas.

Intervenção fonoaudiológica em grupo a cantores populares: estudo prospectivo controlado

“…In the pre-(t 0 ) and post-intervention (t 1 ) periods, all participants filled a protocol (Appendix 1) based on publications of references in this area (7,(10)(11)(12)(13)22) about habits potentially related to voice and vocal health, vocal requirements at work and leisure, as well as aspects related to self-perception of demands and fragilities related to the use of the voice, especially for popular songs. In addition, a perceptive-hearing evaluation took place comparing the two periods, to verify if there had been any improvement on vocal quality as a whole, indirectly considering parameters such as: a) types of voice: adapted, hoarse, breathy or rough (the last ones considered as exclusion factors at the beginning of the study) b) resonance: oral, hyponasal/denasal, hypernasal or balanced c) vocal register: modal, basal or falsetto d) vocal attack: isochronic, abrupt or aspirated e) articulation: adequate, inadequate f) speed of speech and singing: adapted or not adapted g) pitch: low, normal or high h) loudness: weak, medium, strong …”

Uso de substâncias psicoativas, alterações vocais e qualidade de vida em usuários de drogas lícitas e ilícitas

“…The acoustic analysis was carried out using the software VoXmetria version 2.7, The acoustic measures chosen for analysis were: fundamental frequency (Ff -reflex of the biodynamic characteristics of the vocal folds and their integration with subglottal pressure), jitter (indicates short-term Ff variability, measured between glottal cycles), shimmer (indicates the short-term variability in wavelength and is a measure of phonation stability), and Glottal Noise Excitation (GNE) (the acoustic measure that calculates the noise produced by Drug use is very aggressive to the voice mechanism and there are many reports of the use of these substances among some voice professional classes (rock and night club singers, teachers, telemarketing representatives, and salespeople) [18][19][20] . And, even if it is not the norm, it is extremely important that voice therapists are aware of the possible voice changes caused by psychoactive substance use, particularly among voice professionals.…”

Produção fonoaudiológica sobre voz no canto popular

“…Some of the articles included in the present study were conducted with singers of particular musical genres, such as: rock (22) , dance music (23) , Brazilian country (24) , samba (25,26) , bossa nova (26) , pagode (27) , Japanese popular music (28) , regional music (29,30) , singer of the night (31) . A research was conducted with recordings of ballads (32) .…”

“…Voice assessment: corresponded to the most expressive category. Out of 20 researches, 12 focused on assessing the singer's voice, whether on researching aspects of voice quality, of vocal techniques or of laryngeal or vocal adjustments (22)(23)(24)(25)(26)(28)(29)(30)(31)(32)(39)(40) . As examples, we may mention a research which investigatedlaryngeal adjustments of ball singers while imitating the classical style (23) and a study carried out in order to characterize the vibrato in classical and Brazilian country genders (24) .…”

“…No research was located, for example, involving evaluation in loco, which is extremely important to identify habits, postures, working conditions and aspects of the environment which directly interfere in the voice and in the life of popular singers. Tools to collect data used in the researches were: perceptiveauditive evaluation, used in 12 studies (22)(23)(24)(25)(26)(28)(29)(30)(31)(32)(39)(40) ; questionnaires, used in seven researches (22,23,27,32,33,35,41) ; acoustic analysis, used in five studies (23,24,26,32,39) ; imaging evaluation, included videolaryngoscopy, nasofibrolaryngoscopy and videofluoroscopy, used in five studies (23,26,31,(39)(40) ; interviews in two studies (29,34) ; and a literature review, used in four studies researched (33,(36)(37)(38) .…”
