Acoustic Analysis of Madhya and Taar Saptak/Sthayi in Indian Classical Singers.

ABSTRACT

OBJECTIVES: We aimed to compare the acoustic parameters of voice between Madhya Saptak/Sthayi (MS) and Taar Saptak/Sthayi (TS) in trained Indian classical singers and between males and females. PARTICIPANTS AND METHOD: Sixty-five adult trained Indian classical singers were instructed to produce MS and TS; the acoustic parameters were analyzed with the Multidimensional Voice Program. Descriptive statistics were used for analysis across tasks and gender. Two-way random-effects ANOVA was used to test the effect of gender and task. RESULTS: Male participants had a restricted range of fundamental frequency (F0), especially at high pitches. The acoustic analysis showed a statistically significant difference for F0 measures, range of F0, jitter and pitch perturbation quotient between males and females during MS and TS. CONCLUSION: The use of TS, that is, high-pitch phonation, during the clinical evaluation of singers enables an understanding of their vocal behavior in the higher scales of singing.
