'SOVT' is an album containing one 55-minute piece, written for piano by Sarah Hennies in 2017. SOVT stands for Semi-Occluded Vocal Tract which refers to vocal exercises that strengthens the voice by helping the vocal cords vibrate more efficiently. One may practice SOVT exercises by singing with a straw in the mouth which regulates air pressure and reduces strain on the vocal folds. Hennies encountered these exercises in a class on so-called “voice feminization” for transgender women which also inspired her other works “Falsetto” and “Contralto."

Almost all the strings of the piano in this piece are muted with Blu-Tack poster putty and this along with the rhythmic language of the piece results in a sound that is a hybrid piano/percussion-like sound. By connecting all the strings with putty, a dramatically rich sympathetic vibration occurs throughout the piano similar to the way in which one feels increased vibration in the mouth and throat by singing through a straw.

SOVT was originally commissioned by R. Andrew Lee and for this recording was performed by Richard Valitutto, who recorded the work at the Bard College studio in the spring of 2024 with Hennies engineering.
