The xun (simplified Chinese: 埙; traditional Chinese: 塤; pinyin: xūn; Cantonese= hyun1) is a globular, vessel flute from China. It is one of the oldest musical instruments in China and has been in use for approximately seven thousand years. The xun was initially made of stone, baked clay, or bone, and later of clay or ceramic; sometimes the instrument is made with bamboo. It is the only surviving example of an earth (also called "clay") instrument from the traditional "eight-tone" (bayin) classifications of musical instruments (based on whether the instrument is made from metal, stone, silk, bamboo, gourd, earth, hide, or wood).
