Overtone Singing

Overtone singing is a vocal technique where a singer produces a single fundamental note while simultaneously shaping their voice to emphasize certain higher frequencies, known as overtones or harmonics. By adjusting their mouth shape, tongue position, and airflow, the singer causes these overtones to become audible, creating a shimmering, multi-layered sound. This technique allows a single voice to sound like multiple pitches at once, often resembling a drone with harmonics floating above it. Overtone singing is used in various musical traditions worldwide and showcases the singer’s control over their vocal apparatus to produce complex, ethereal tones.
