A transverse flute or side-blown flute is a flute which is held horizontally when played.1 The player blows across the embouchure hole, in a direction perpendicular to the flute's body length.2

Transverse flutes include the Western concert flute, the Irish flute, the Indian classical flutes (the bansuri and the venu), the Chinese dizi, the Western fife, a number of Japanese fue, and Korean flutes such as daegeum, junggeum and sogeum.
