The riq (also spelled riqq or rik) is a type of tambourine used as a traditional instrument in Arabic music. It is an important instrument in both folk and classical music throughout the Arabic-speaking world. It traditionally has a wooden frame (although in the modern era it may also be made of metal), jingles, and a thin, translucent head made of fish or goat skin (or, more recently, a synthetic material).
The player alternates between striking the membrane and shaking the jingles, and his need for freedom of movement necessitates that he stand up. Students of the instrument are required to master the technical problems imposed by the timbre of the membrane and the jingles, both separately and in combination; aside from developing a virtuoso technique they also need to learn the many rhythmic cycles and the techniques of modifying them through creative invention.
