Kazoo is one of the easiest instruments to play.Both children and adults find it very interesting KAZOO's pronunciation principle: playing KAZOO does not need to learn music theory, does not need to recite music, or even practice. Because it is small and easy to carry, you can play at any time. KAZOO is a big, small one. When playing the big head in the mouth, it does not need to blow air, but hums with the voice. The vibration of the vocal band drives the vibration of the KAZOO film to sound. It is the key to sound the voice with the voice. If you are a expert, please forgive my statement.Change the tone of the kazoo by rotating the lid on the flute diaphragm. When the lid is twisted to tight, it sounds more crisp. On the contrary, it sounds more hoarse. Replaceable Kazoo Flute Diaphragms The structure of KAZOO is simple and the membrane can be replaced.Preservative film and flute film can be replaced.
