Throat-singing is a guttural style of singing or chanting. It is considered one of the world's oldest forms of music.
In throat-singing a singer can produce two or more notes simultaneously through a specialized vocalization technique, taking advantage of the throat's resonance characteristics.
By precise movements of the lips, tongue, jaw, velum, and larynx, throat-singers produce unique harmonies using only their bodies.
Throat-singing is most identified with parts of Central Asia, but it is also practiced in northern Canada and South Africa.
