Sheng is a traditional Wind Instrument. Like a piano, it is capable of producing a chord of ten notes. Each note is produced by a bamboo tube and reed. Its structure is the most complicated in the Wind Section.

The original version of Sheng is made up of a group of bamboo tubes of different lengths that are tied together with a string. Later improvements added reeds to each tubes. The early Sheng had thirteen to seventeen bamboo tubes. In AD 1006, the Bei Song Dynasty, 19-tubes Sheng was used. In the Ming and Ching Dynasty, popular Sheng were 17-tubes, 14-tubes, 13 tubes and 10-tubes. In modern China, further improvements were made, and the 21-tubes, 24-tubes, 26-tubes, 27-tubes, 32-tubes, 36-tubes, and 51-tubes Sheng were produced. Such arrangements allow Sheng to play complicated chords and music.
