The oud is a coursed Middle Eastern instrument of the lute family, and is often said to be the ancestor of the European renaiassance and baroque lutes. Courses are double except for one or two bass courses.

Modern ouds have five or six courses except in Iraq where seven courses is normal, with all but the lowest course double, and are fretless. Older ouds had movable frets, and some were tuned for quartertone equal temperament.
