The music of Qinghai, a province of China inhabited by Tibetans, Mongolians, Salar, Han, Monguor (Tu), and others, includes hua'er, a type of song found in certain areas of northwest China. This informal music is often competitive in nature, with singers interacting and improvising topical and love lyrics, usually unaccompanied. Qinghai's folk music is known for its intervallic leaps in melody.[1]
