Forming Sounds (1972)

Phyllis is asked to repeat a steady unmodulated hum for 25 minutes. Using my hands between her mouth and the microphone, I attempt to regulate the acoustics. Mid-way through, either her mouth or the microphone is touched. The modulation occurs between these two points. The hand acts as a sound block. Attempts are made to echo sounds of her face.
