Comparing Contemporary Commercial and Classical Styles: Emotion Expression in Singing

The results differed somewhat for the CCM and classical styles. The alpha ratio showed less variation in the classical style, most likely reflecting the demand for a more stable voice source quality. The alpha ratio, F1, F2, shimmer, amplitude vibrato rate, and the sustain time of the vocalizations were related to fo and SPL control in the classical style. The only common independent sound parameter indicating emotional expression for both styles was SPL. The CCM style offers more freedom for expression-related changes in voice quality.
