The kazoo is a musical instrument that adds a buzzing timbral quality to a player's voice when the player vocalizes into it. It is a type of mirliton (itself a membranophone), one of a class of instruments that modify the player's voice by way of a vibrating membrane of goldbeater's skin or material with similar characteristics. There is a smaller version of the kazoo, known as a humazoo.
