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.
