The double-pipe mabu is a single-reed air-sounding instrument unique to the Yi people. In Yi language, "horse" means bamboo, and "cloth" means reed pipe, which means a bamboo air-sounding instrument with a reed pipe inserted.

The timbre of the double-pipe Mabu is crisp and melodious. When it is used to play cheerful and lively melodies, it is bright and rough; when it is used to play sad and slow tunes, it is affectionate and slightly nasal, especially when it is played to a long tail. The music is like weeping and complaining, which is very moving. Mabu's playing skills are more difficult, and some fast and complex pieces require more skilled playing skills. It is often used as a solo, ensemble or accompaniment for singing and dancing, and is a distinctive and expressive instrument. Its playing techniques and solo repertoire are the same as single-pipe mabu.

The traditional solo pieces include "Tiger Out of the Hole", "Cuckoo Crossing the Mountain", "Morning Wind Shaking Bamboo", "Ten Thousand Horses Running to the Beach", etc. Ganluo's popular Mabu songs include "Sheep Sheep Tune", "Let the Dog Drive the Mountain" ", "Harvest Tune" and "Happy Tune", etc. Ninglang's popular music includes "Buja Tune" and so on.
