The tenor holding sheng is similar to the round sheng, but it is large and needs to be played on the lap. The bass sheng should be played on a wooden frame. Paisheng is a desktop, the sound of the sheng pipe is controlled by the buttons, and a bellows with foot steps is attached to assist the drumming, which can be played for a long time without interruption. The keyboard arrangement of sheng is based on the pronunciation principle of sheng and reed, combined with the reform of the keyboard device of the organ. It has 51 keys, four groups of sound ranges, and the finger skills are the same as those of the organ. Sheng and Fang Sheng are more convenient.
