Description
Summary:Purpose: to identify the immediate effect of the sonorous tongue-trill technique associated with tonal variation on the vocal range profile of chorists, analyzing time spent on choral singing, voice types and exercises. Methods: quantitative cross-sectional study, with 13 singers, eight women and five men, mean age of 39 [+ or -] 20.11 years, with different voice types. The vocal range profile was obtained using Vocalgrama software (CTS Informatica). Samples were collected at three different times: before, after one minute and after two minutes of applying the sonorous tongue-trill technique associated with tonal variation. Results: six chorists (46.2%) showed an increase in vocal range profile after two minutes of the technique. Sopranos and tenors obtained higher mean vocal range profile at any of the three times considered. Conclusion: the sonorous tongue-trill technique associated with tonal variation had no effect on the vocal range profile of the chorists under study. However, time spent on exercises and voice types seemed to have an influence on the results. Keywords: Singing; Evaluation; Acoustics; Voice Training; Treatment Outcome Objetivo: identificar o efeito imediato da tecnica de vibracao sonorizada de lingua associada a variacao tonal sobre o perfil de extensao vocal de coristas, analisando o tempo de pratica de canto, naipe e tempo de execucao do exercicio. Metodos: estudo transversal quantitativo, com 13 cantores, sendo oito mulheres e cinco homens, com media de idade de 39[+ or -] 20,11 anos, pertencentes a diferentes naipes. O perfil de extensao vocal foi obtido a partir da analise pelo software Vocalgrama da CTS Informatica. As amostras foram coletadas em tres momentos: antes, apos um minuto e apos dois minutos de aplicacao da tecnica de vibracao sonorizada de lingua associada a variacao tonal. Resultados: seis coristas (46,2%) aumentaram o valor do perfil de extensao vocal, apos dois minutos de execucao da tecnica. Os naipes sopranos e tenores apresentaram valores medios maiores do perfil de extensao vocal apos dois minutos de exercicio. Em relacao ao tempo de pratica de canto, nao houve diferenca entre os grupos no valor do perfil de extensao vocal em nenhum dos tres momentos considerados. Conclusao: a tecnica de vibracao sonorizada de lingua associada a variacao tonal nao interferiu no perfil de extensao vocal dos coristas estudados. Entretanto, o tempo de execucao do exercicio parece influenciar nos resultados. DECRITORES: Canto; Ava
