Andalusī nūbah (نوبة أندلسيّة), also transliterated nūba, nūbā, or nouba (pl. nūbāt), or in its classical Arabic form, nawba or nawbah, is a musical genre found in the North African Maghrib states of Morocco, Algeria, Tunisia, and Libya but, as the name indicates, it has its origins in Arabo-Andalusian music. The name replaced the older use of sawt and originates from the musician waiting behind a curtain to be told it was his turn or nawbah by the sattar or curtain man .
