Huun-Huur-Tu (Tuvan: Хүн Хүртү Khün Khürtü, Russian: Хуун-Хуур-Ту) is a music group from Tuva, a Russian Federation republic situated on the Mongolian border.
The most distinctive characteristic of Huun Huur Tu's music is throat singing, in which the singers sing both the note (drone) and the drone's overtone(s), thus producing two or three notes simultaneously. The overtone may sound like a flute, whistle or bird, but is solely a product of the human voice.
