Playing Kazoo doesn't need music theory, spectrum or even practice! This kazoo has been carefully designed with a stylish yet comfortable design, making it a chore for every individual. If the player can sing the song, you can play with the kazoo and soon you can master the game skills. The resulting sound changes according to the pitch and height of the player's hum. Players can produce different sounds by saying certain syllables. Fun for all ages around the campfire, family and holiday gatherings or any outdoor activity.
