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. However, time spent on exercises and voice types seemed to have an influence on the results.
