ABSTRACT
The singing voice as a musical instrument is inexactly understood because its mechanism of production is invisible. Voice is vibration: an exhaled stream of air passes from lungs to larynx, where it opens muscles like valves that regulate it, resist its escape, and, vibrating, produce sound; to resonating cavities of the upper body and head; and to the pharynx, where sound and tone quality is shaped, pitched, projected-“placed” by mouth, tongue, palate, lips.2
