Like the musical genres of the Nile Valley and the Horn of Africa "(sky-blue and dark green region on map)", its music has close ties with Middle Eastern music and utilizes similar melodic modes ("maqamat"). North African music has a considerable range, from the music of ancient Egypt to the Berber and the Tuareg music of the desert nomads. The region's art music has for centuries followed the outline of Arabic and Andalusian classical music: its popular contemporary genres include the Algerian Raï.
