Andalusian classical music (Arabic: طرب أندلسي‎, romanized: ṭarab ʾandalusī; Spanish: música andalusí) or Andalusi music is a genre of music originally developed in al-Andalus by the Muslim population of Andalusia and the Moors, it then spread and influenced many different styles across the Maghreb (Algeria, Morocco, Tunisia, and Libya) after the Expulsion of the Moriscos. It originated in the music of Al-Andalus (Muslim Iberia) between the 9th and 15th centuries. Some of its poems derive from famous authors such as Al-Shushtari, Ibn al-Khatib and Al-Mu'tamid ibn Abbad.
