The Clarke Kazoo is made from 100% selected tinplate and finished in either natural silver or gold lacquer. The sound is adjustable by turning the membrane holder, and the membrane is replaceable. The Clarke Tinwhistle Kazoo produces a pleasant ‘buzzing’ sound when you hum, sing or speak into it. The quality of the sound is very much dependant on the standard of the player, if you can sing or hum in tune – then you can play the kazoo. The kazoo is a member of the ‘Membranophone’ musical classification, which is in the percussion instruments, as the sound is created through a stretched membrane. The Clarke Kazoo comes with an instruction sheet, and it is presented in a tube shaped container which is perfect for keeping the instrument safe and sound.
