The Chinese Kerbspaltflöte Xiāo(pronounced Schiou) is, so to speak, the great-grandmother now much better known Japanese shakuhachi and is made from bamboo roots. Just as it is also they have a notch on the upper end of the tube blown at. Because of the somewhat modified form of Anblaskerbe her tone can be a bit more stable than in keeping the Japanese version. Their sound is very soft, deep and restrained. Originally it served Buddhist monks as a meditation tool, before 500 years ago came to Japan. The Xiao will be played either solo or in ensemble together with the board fretless Chinese zither Gu Qin.
