pharynx
PHARYNGEAL SPACE
A constricted pharynx leads to a thin, breathy sound and heightened pitch. Expanding the pharynx, as one does when stifling a yawn, adds roundness to the sound. Though it is more often than not linked to pharyngeal expansion, attention should also be given to lowering the larynx. This combination allows the sound to be round and have depth of color. Without a slightly lowered larynx, the sound can (though round and lovely) become sharp in pitch. The expanded pharynx and lowered larynx together form the foundation of beautiful tone. They should remain open and supple while you create a diverse palette of colors with air speed, air pressure, and varying vowels and consonants.
