A tambourine is an example of a: a. percussion instrument b. wind instrument c. string instrument d. brass instrument

A tambourine is a percussion instrument. It consists of a frame, an open cylinder of wood or plastic, with drumheads of skin or synthetic material on both ends. The bottom drumhead is played with the hand or a drum stick, while the top drumhead is traditionally filled with small jingles, which are struck with the hand or a small stick to produce a sound. The tambourine is not a wind instrument, as it does not produce sound by the vibration of air. It is also not a string instrument, as it does not produce sound by the vibration of strings. Lastly, it is not a brass instrument, as it does not produce sound by the vibration of a brass tube. Therefore, the correct answer is option a, a percussion instrument.
