Perfil de extensão vocal em coristas após técnica de vibração de língua associada a escalas

Abstract

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± 20.11 years, with different voice types. The vocal range profile was obtained using Vocalgrama software (CTS Informática). 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.

Análise acústica da voz: comparação entre dois tipos de microfones

“…Some international studies compared the use of different microphones; however, they were mostly imported high-cost microphones, that does not represent the reality of most institutions and voice clinics in Brazil. Commonly, the Karsect HT-9 microphone is used among Brazilian professionals because it also provides the interface Andrea PureAudio™ USB-SA (Andrea Electronics) (15)(16)(17)(18) . International studies commonly use the Shure SM58 microphone (19)(20)(21)(22) coupled with high-quality recording interfaces.…”
