The Daf is a large Persian and Arabic frame drum used in popular and classical music. The frame is usually made of hardwood with many metal ringlets attached, and the membrane is usually fish skin but other skin types such as the cow, goat, and horse are used. The Daf is mostly used in Iran, Arab world, Indian subcontinent, Kurdistan, and Central Asia, and usually accompanies singers and players of the Tanbur, Violin, Oud, and other Middle Eastern instruments.
