The tambourine is a musical instrument in the percussion family consisting of a frame, often of wood or plastic, with pairs of small metal jingles, called "zills". Classically the term tambourine denotes an instrument with a drumhead, though some variants may not have a head. Tambourines are often used with regular percussion sets. They can be mounted, for example on a stand as part of a drum kit (and played with drum sticks), or they can be held in the hand and played by tapping, hitting, or shaking the instrument.

Tambourines come in many shapes with the most common being circular. It is found in many forms of music: Arabic folk music, Turkish folk music, Greek folk music, Italian folk music, French folk music, classical music, Galician traditional music, Persian music, samba, gospel music, pop music, country music, and rock music.
