Ducted flutes use a fipple to direct the air stream from the player's mouth on to a bevelled edge mechanically instead of directly as in the ney embouchure. This simple device exists throughout Eurasia and in native north America where it was adapted from the European recorder. In the Andes the more ancient notched flute, the quena, is played (it's not really a ducted flute but closer than a plain end-blown flute, so I've included it on this page). The ocarina is a type of closed fipple flute. Overtone flutes, with their complex breathy sound, commonly employ fipples; examples of this are the Norwegian seljefløyte and similar overtone flutes in eastern Europe. In Slovakia the fujara, a contrabass fipple flute, uses a combination of overtones and finger holes.
