A tambourine is a percussion instrument comprising a shallow frame drum attached to bells or cymbals which jingle as it is played. These bells are called zils. The word 'tambourine' comes from the Persian tambur, or drum. The tambourine is used in folk music all around the world, though its design varies.
The tambourine gained notoreity in recent decades through Bob Dylan's Mr Tambourine Man, featured on his 1965 album Bring it all Back Home. The Byrds also covered the song, and unlike Dylan they used a tambourine: Listen on Spotify.
