Another recognisable family consists of the Iraqi (Mosul and Iraqi diaspora), Spanish-Moroccan and Spanish and Portuguese melodies. The probable reason for the occurrence of similar melodies at opposite ends of the Arab world is that they represent the remains of an old Arab-Jewish tradition not overlaid by the later Ottoman-Sephardic tradition that spread to the countries in between. There may also have been some convergence between the London Spanish and Portuguese and Iraqi melodies during British rule in India and the British Mandate of Mesopotamia.
