endblown
Endblown refers to a method of sound production used by certain wind instruments, most commonly flutes, in which the player blows air directly into the end of the bore and the air is split by an edge or notch at the instrument’s mouth opening. This contrasts with side-blown flutes, where the airstream is directed across the edge on the side of the bore, and with fipple or duct flutes, where the air is guided by a built-in mouthpiece.
In endblown instruments the pitch is typically changed by opening and closing finger holes along the bore
Notable examples of endblown flutes include the shakuhachi of Japan, the xiao of China, and the ney
