The only earthen musical instrument is a kind of ocarina called Xun. It can produce sound with a tamber similar to that of human voice, and is suitable for performing some lamenting aria. People in ancient times used the instrument to imitate birds' sound and ensnare them.
The oldest Xun that has been discovered in China up to now was made about six to seven thousands years ago. For instance, a conical Xun was discovered in the Hemudu of the Hangzhou Bay in Zhejiang Province (eastern China), the Xun without holes and the one-hole Xun were found in the Yangshao Culture site in Banpo Village in Xi'an (western China) and Xun was also discovered in Wanrong County of Shanxi Province (northern China), Yumen Huoshao Gou of Gansu Province (northwestern China) and Huixian County in Henan Province (central China).
