Edge-blown Flutes

Edge-blown flutes generate sound when an air stream is blown directly across the edge of a hole in the instrument, causing the air column to split.

Two types of Edge-blown flutes include:

–  Blow-hole flutes which the player blows against the sharp rim at the end (end-blown) or hole in the side (transverse) of the flute.  

 –  Whistle (duct) flutes, that generates sound when an air stream is blown through a chamber or duct and directed to an opening where the air is split to create a sound.
