Shuanglelang (pinyin: shuāng lè làng) Shuanglelang is a double-reed gas-sounding instrument of the Buyi nationality. Popular in Shuanglelang, the Bouyei double-reed air-sounding instrument. The shape is the same as the Bouyei single-tube Lelang, which is made of two Lelangs with the same length, thickness and pitch tied side by side. There is also a curved connecting pipe inserted into the mouth of two side-by-side pipes, sharing a reed whistle.
