The Tar is a simple and ancient frame drum. A round frame, usually made of wood, is fitted with a drum head, usually made from an animal skin. The Oud is a guitar-like instrument typically with eleven strings. It does not have frets on the neck like a guitar. Frets are the ridges on the neck of the guitar that help a player find the notes. The oud is recognizable by the deep, round, pear-shaped body and bent neck. Both the Tar and Oud are used throughout the Middle East and Northern Africa.
