A Steinway retail location in California.

The Original American Kazoo Company, Eden, New York

Although it is not taken seriously in some musical circles, the simple kazoo is an American musical invention that deserves more recognition and respect than it receives. For the many who don’t know what a kazoo is, it’s a musical instrument that adds a buzzing or timbral quality to a player’s voice when they vocalize or hum into it.

Technically, it’s a type of mirliton, a class of instruments that modifies its player’s voice by way of a vibrating membrane (most commonly made of waxy paper). Typically, a kazoo player hums into the instrument creating oscillating air pressure that makes the membrane vibrate.

The resulting sound varies in pitch and loudness with the player’s humming. It is easy to play, which helps explain its popularity among amateurs. The origin of the kazoo is sketchy but it was developed in America in the 1880s.

In 1916, the Original American Kazoo Company began manufacturing metal kazoos for the masses in a two-room shop in Eden, New York. By 1994, the company was producing 1.5 million kazoos per year and was the only remaining maker of the instrument — a distinction it retains to this day.

Visitors can watch metal kazoos being turned out, much the way they were from the start in 1916, at the company’s combination factory and museum. Guided tours ($2 pp) are available on Tuesdays and Thursdays, but please call at least one day ahead to schedule an appointment., 716-992-3960
