Flutes
Flutes generates 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 flutes include:
A) Blow-hole flutes in which the player blows against the sharp rim at the end (end-blown) or hole in the side (transverse) of the flute. These may include the transverse flute, piccolo, fife, etc.
B) Fipple (duct) flutes 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. These may include recorders, flageolets, whistles, ocarinas, etc.
