Please help Kazoo

    What are the physics principles behind the tribal instrument Kazoo? It is just a long tube and a hole in the middle and a rubber piece covering 1 end of the tube.

    Vibration (resonance) in the air column establishes vibration in the membrane. The membrane has certain natural frequencies at which response will be stronger.

    Does the membrance changes the timble of the sound as it resonance it?

    Also since it "reflect" the sound - does it also amplifies it?

    Many thanks for the answer.
