A kazoo is a simple musical instrument that allows the player to create a distinctive, buzzing sound by humming into it. It consists of a hollow chamber with a thin membrane, typically made of wax paper or plastic, stretched across one end. When the player vocalizes into the kazoo, the vibrations from their voice cause the membrane to vibrate, producing the characteristic buzzing tone. Kazoos are inexpensive, portable, and easy to play, making them popular novelty instruments often used in comedy music, jug bands, and children's performances. Despite their simplicity, kazoos can be played to mimic various sounds, from animal noises to sirens, and even to perform melodies and harmonies.From Lehman's: Kids love all the fun noises they make. Adults enjoy using them in string bands, jazz ensembles or kazoo choirs. Made from metal for better sound. Just hum into the mouthpiece (the larger end). For ages 10 and up. 4-3/4" L. USA made.
