Subglottal pressure

Musical Theater and Opera Singing—Why So Different? A Study of Subglottal Pressure, Voice Source, and Formant Frequency Characteristics (Article)
This voice science article examines the timbre differences in Musical Theater and Classical Singing. The author examines the different demands of each singer and takes into account microphone usage and the number of weekly performances. Björkner asserts that subglottal pressure is the main player in controlling vocal intensity. Five male opera singers and five mail MT singers were involved in this study, which seeks to determing "voice source characteristics" and formant frequencies at two fundamental frequencies (f0) and over a large dynamic range. Results indicate that MT and opera singers both sing with equally pressed phonation and that the singer's formant plays a large role in classical vs. MT singing. (posted 2:34 PM, August 27, 2014)
