The Chinese sheng (Chinese: 笙; Pinyin shēng) is a mouth-blown free reed instrument consisting of vertical pipes.
Traditionally, the sheng has been used as an accompaniment instrument for solo suona or dizi performances. It is one of the main instruments in Kunqu Opera and some other forms of Chinese opera. Traditional small ensembles also make use of the sheng, such as the wind and percussion ensembles in northern China. In the modern large Chinese orchestra, it is used for both melody and accompaniment.
