This information may be useful in improving the training of interpretation in singing. STUDY DESIGN: This is an experimental comparative study. METHODS: Eleven female singers with a minimum of 3 years of professional-level singing training in CCM, classical, or both styles participated. They sang the vowel [a:] at three pitches (A(3) 220Hz, E(4) 330Hz, and A(4) 440Hz) expressing anger, sadness, joy, tenderness, and a neutral voice. Vowel samples were analyzed for fundamental frequency (fo) formant frequencies (F1-F5), sound pressure level (SPL), spectral structure (alpha ratio = SPL 1500-5000 Hz-SPL 50-1500 Hz), harmonics-to-noise ratio (HNR), perturbation (jitter, shimmer), onset and offset duration, sustain time, rate and extent of fo variation in vibrato, and rate and extent of amplitude vibrato. RESULTS: The parameters that were statistically significantly (RM-ANOVA, P
