笙 — Shēng
The Chinese sheng (Chinese: 笙; Pinyin shēng) is a mouth-blown free reed instrument consisting of vertical pipes.
It is one of the oldest Chinese instruments, with images depicting its kind dating back to 1100 BC, and there are actual instruments from the Han era that have been preserved today. 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 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.
The sheng has been used in the works of a few non-Chinese composers, including Lou Harrison, Tim Risher, Daniel Bjarnason, Brad Catler, and Christopher Adler. Some believe that Johann Wilde and Pere Amiot traveled to China and brought the first shengs to Europe in 1740 and 1777 respectively, although there is evidence that free reed musical instruments similar to shengs were known in Europe a century earlier.
The sheng's reeds vibrate at a fixed frequency, unlike single reeds, double reeds and pointed free reeds which vibrate at the pitch according to the length of the attached air column. Covering a hole on the sheng's pipe causes the entire length of the pipe to resonate with the reeds' frequency. If the hole is open, the resonance frequency would not match, and hence no sound is produced.
Play Shēnɡ
The sheng is played by alternately blowing and inhaling, and a player can produce a continuous sound without pause. The traditional performance style is to sound two or three notes at the same time by adding a fifth and/or octave above the main melody note. When a higher note is not available, a lower note a fourth below the main melody note can be played instead.
