The mazhar (Arabic: مظهر; plural mazāhar, مظاهر) is a large, heavy tambourine used in Arabic music. The mazhar's frame is generally made out of wood. The instrument's brass jingles are quite large (4-5 inches / 10–13 cm in diameter). It is played with a shaking technique that gives it a raucous sound. Its single head is considerably thicker than that of the riq, its smaller cousin.
The Egyptian percussionist Hossam Ramzy is a notable performer of the mazhar.
