Zajal ( Arabic: زجل) is a traditional form of oral strophic poetry declaimed in a colloquial dialect. While there is little evidence of the exact origins of the zajal, the earliest recorded zajal poet was the Andalusian poet Ibn Quzman (who lived from 1078 to 1160). It is generally conceded that the early ancestors of Levantine dialectical poetry were the Andalusian zajal and muwashshaḥah, brought to Egypt and the eastern Mediterranean by Arabs fleeing Spain in the thirteenth and fourteenth centuries. An early master of Egyptian zajal was the fourteenth century zajjāl Abu ʿAbd Allāh al-Ghubārī. Zajal's origins may be ancient but it can be traced back to at least the 12th century. It is most alive in Lebanon today, and the Maghreb and particularly Algeria, and in the Levant, especially in Lebanon, Palestine and in Jordan where professional zajal practitioners can attain high levels of recognition and popularity. Zajal is semi-improvised and semi-sung and is often performed in the format of a debate between zajjalin (poets who improvise the zajal). It is usually accompanied by percussive musical instruments (with the occasional wind instrument, e.g. the ney) and a chorus of men (and more recently, women) who sing parts of the verse.
Egyptian poets known for their literary use of the popular zajal form are Yaqub Sanu, 'Abd Allah al-Nadim, Bayram al-Tunisi, and Ahmed Fouad Negm. Well-known Lebanese zajjaali include Zein Sh'eib, Talih Hamdan, Zaghloul alDamour, Moussa Zgheib, Asaad Said, and Khalil Rukoz.
