The hulusi (traditional: 葫蘆絲; simplified: 葫芦丝; pinyin: húlúsī) or cucurbit flute is a free reed wind instrument from China. It is held vertically and has three bamboo pipes which pass through a gourd wind chest; the center pipe has finger holes and the outer two are typically drone pipes. It is not uncommon for a hulusi to have only one drone pipe while the second outer pipe is merely ornamental. The drone pipe has a finger hole, which allows it to be stopped. Advanced configurations have keyed finger holes similar to a clarinet or oboe, which can greatly extend the range of the hulusi to several octaves.
The hulusi was originally used primarily in Yunnan province by a number of ethnic-minority groups, in particular the Dai people who calls the instrument "bilangdao" (筚朗叨), and has gained nationwide popularity throughout China; similar to the popularity of the harmonica in the West, and "improved" versions have been produced outside of the indigenous realms. Like the related free reed pipe called bawu, the hulusi has a very pure, very mellow clarinet-like sound.
A similar instrument called hulusheng is a mouth organ with a gourd wind chest.
