Huun-Huur-Tu is a throat singing group from Tuva, Russian Federation situated north of Chinese Turkestan, west of the Mongolian border. The Tuvan throat singing technique allows one person to sing in a way that makes the listener hear different/multiple notes at the same time from the same singer. This is done by manipulating the harmonics to amplify different overtones within their mouth/throat/belly when they are singing, and is referred to as khoomei in its native tuva.
