Huun-Huur-Tu are a music group from Tuva, a Russian federative republic situated on the Mongolia-Russia border. Their music includes throat singing, in which the singers sing both a note and its overtones, 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.
The group primarily use native Tuvan instruments such as the igil, khomus, doshpuluur, and dünggür. However, in recent years, the group have begun to selectively incorporate Western instruments, such as the guitar. While the thrust of Huun-Huur-Tu's music is fundamentally indigenous Tuvan folk music, they also experiment with incorporating Western instruments and electronic music.
