Woodwind instruments

Annotations:

• The air vibrates when it hits a hole with a sharp edge. This occurs in recorders and transverse flutes.

Annotations:

• Vibrating air produces sound when it hits a reed or strip of cane in the mouth piece of the instrument. For example: clarinets and saxophones.
