Oud is a pear-shaped stringed instrument commonly used in Arabic, Greek, Turkish, Persian, Jewish, Byzantine, Azerbaijanian, Armenian, North African (Chaabi, Classical, and Spanish Andalusian), Somali and Middle Eastern music. Construction of the oud is similar to that of the lute. The modern oud and the European lute both descend from a common ancestor via diverging paths. One instrument that has been suggested as ancestral is the Barbat. The oud is readily distinguished from the lute by its lack of frets and smaller neck. Alongside the lute, it is considered an ancestor of the guitar.
