Kazoo. A kazoo is a type of instrument known as a mirliton, which uses a resonating membrane to amplify sound. It belongs in the percussion family of instruments and can be made in a number of ways. Derived from the ancient African mirliton, the kazoo was first manufactured during the 1800s.he kazoo relies on the voice of the musician to produce the sound. When a musician plays a kazoo, he hums into it and that causes the thin film to vibrate. This vibration changes with the sound of the voice giving it the buzzing quality, which is unique to the kazoo.
