Qiangdi is an ancient single-reed musical instrument in China with a history of more than 2,000 years. Popular in Qiang folk houses in Aba Tibetan and Qiang Autonomous Prefecture in northern Sichuan.
The two pipes of Qiangdi have several holes (previously five holes, now mostly six holes), which are made of oil bamboo growing on the local mountain. Bamboo joints are long and thin, growing at an altitude of 3500-4000 meters. The two pipes are connected side by side by wire winding. Longevity 13 ~ 19 cm, the diameter of the nozzle is about 2 cm, and the upper end of the flute tube is equipped with a bamboo mouthpiece with a length of 4 cm. The front of the mouthpiece is flattened with a knife, and a thin piece is cut with a knife at the upper end about 3 cm as a reed.
Qiangdi is mainly used for solo and more than ten ancient songs. The content of music is quite extensive, mainly to convey the yearning of Qiang people.
