Effects of a Straw Phonation Protocol on Acoustic Measures of an SATB Chorus Singing Two Contrasting Renaissance Works

摘要

Background. Researchers have found that semi-occluded vocal tract (SOVT) exercises may increase vocal economy by reducing phonation threshold pressure and effort while increasing or maintaining consistent acoustic output. This research has focused solely on individual singers. Much singing instruction, however, takes place in choral settings. Choral singers may use different resonance strategies or unconsciously adjust their singing based on the ability to hear their own sound in relation to others. Results of studies with individual singers, then, may not be directly applicable to choral settings.
