This is a tough institutional Kazoo made of soft strong plastic.
This is a first class product and a great product for the classroom.
A kazoo player hums, rather than blows, into the instrument.
The oscillating air pressure of the hum makes the kazoos membrane vibrate.
The resulting sound varies in pitch and loudness with the players humming.
Players can produce different sounds by singing specific syllables such
as doo, who, rrrrr or brrrr into the kazoo.
