Everyone is familiar with the harmonica. Its enchanting sound arises from the fact that the musician, blowing air into the instrument, makes a small metal tongue vibrate, which produces the sound. Reeds include accordions, button accordions, accordions, and kazoos. In addition, reed wind instruments, such as saxophone, bassoon or clarinet, can be attributed to them, the sound in which is generated due to the vibration of a small wooden plate - a cane.
