Chinese flutes come in various types. They include
Transverse Flutes:
End-Blown Flutes (air split directly on mouthpiece):
(Uyghur and Mongolian minorities also play a version of the Turkish ney.)
Fipple Flutes (air split through whistle flue duct):
Free-Reed flutes (use free-reed instead of splitting the airway, but otherwise play in a similar capacity to flute in terms of breath support and fingering.):
Chinese flutes are generally made from bamboo and belong to the bamboo classification of Chinese music, although they can be (and have been) made of other materials such as jade.
