Semi‐occluded vocal tract postures and their application in the singing voice studio

Many singing teachers employ semi‐occluded vocal tract postures in their teaching. These postures can be divided into three types: (1) postures where the semi‐occlusion remains consistent over time, as in singing vowels into a straw, the sustained phonation of voiced fricative consonants and the sustained phonation of nasal consonants; (2) postures where the occlusion is oscillatory, as in the lip buzz, the raspberry, and the rolled /r/; (3) postures where the semi‐occlusion or occlusion is very transitory, as is found in the semi‐vowels /j/ and /w/ and the voiced plosive consonants. The presentation will review the benefits of these semi‐occluded postures, show videoendoscopic images of the pharynx and larynx and electroglottography of the vocal folds while the semi‐occluded postures listed above are used as pilots to the vowels /i/, /u/, and /a/, and will demonstrate some of the traditional uses of the semi‐occluded postures in singing pedagogy.
