What is "duxianqin"

The duxianqin (独弦琴, pinyin: dúxiánqín; lit. "lone string zither", pronounced ), also yixianqin (一弦琴, lit. "one string zither"), is a Chinese plucked string instrument with only one string.

The duxianqin is nearly identical to the Vietnamese đàn bầu, from which it is likely to have been derived. Chinese sources describe đàn độc huyền as being an instrument of the Jing (also spelled Gin or Kinh) ethnic group of China, who are ethnic Vietnamese living in China It is still sometimes played by these ethnic groups. Sometimes the body of the instrument is made from a large tube of bamboo rather than wood, which is more common in Vietnam.
