The oud is one of the oldest string instruments in Middle Eastern music, with roots in ancient Mesopotamia and Persia and a name derived from the Arabic word for wood. Played across the Arab world, Turkey, Iran and North Africa for centuries, it became the lead melodic instrument in traditional ensembles and solo improvisation. Its fretless neck allows the slides and quarter tones heard in maqam scales. Recordings of solo oud playing now circulate widely online as background for cultural, historical and travel content.
