Another division is between side-blown (or transverse) flutes, such as the Western concert flute, piccolo, fife, dizi and bansuri; and end-blown flutes, such as the ney, xiao, kaval, danso, shakuhachi, Anasazi flute and quena. The player of a side-blown flute uses a hole on the side of the tube to produce a tone, instead of blowing on an end of the tube. End-blown flutes should not be confused with fipple flutes such as the recorder, which are also played vertically but have an internal duct to direct the air flow across the edge of the tone hole.
