Hmmmmmm... If You Can Hum, You Can Play!
The classic metal Kazoo! Anyone can be musical when they have a Kazoo.
The Kazoo belongs to the family of instruments known as “Mirlitons”, characterized by having a vibrating membrane. The Kazoo’s closest relative is the African Horn-Mirliton, made from the horn of a cow with a membrane made from the eggshells of spiders.
This one is made of metal with a plastic membrane.
