Muwashshah in the context of "Arabic music"

Andalusi Romance, also called Mozarabic, refers to the varieties of Ibero-Romance that were spoken in Al-Andalus, the parts of the medieval Iberian Peninsula under Islamic control. Romance, or vernacular Late Latin, was the common tongue for the great majority of the Iberian population at the time of the Umayyad conquest in the early eighth century, but over the following centuries, it was gradually superseded by Andalusi Arabic as the main spoken language in the Muslim-controlled south. At the same time, as the northern Christian kingdoms pushed south into Al-Andalus, their respective Romance varieties (especially Castilian) gained ground at the expense of Andalusi Romance as well as Arabic. The final extinction of the former may be estimated to 1300 AD.

The medieval Ibero-Romance varieties were broadly similar (with Castilian standing out as an outlier). Andalusi Romance was distinguished from the others not by its linguistic features primarily, but rather by virtue of being written in the Arabic script. What is known or hypothesized about the particular linguistic features of Andalusi Romance is based on relatively sparse evidence, of which the kharjas, or closing lines of an Andalusi muwaššaḥ poem, are the most important.

Andalusi Arabic or Andalusian Arabic (Arabic: اللهجة العربية الأندلسية, romanized: al-lahja al-ʿarabiyya al-ʾandalusiyya) was a variety or varieties of Arabic spoken mainly from the 8th to the 15th century in Al-Andalus, the regions of the Iberian Peninsula under the Muslim rule.

Arabic spread gradually over the centuries of Muslim rule in Iberia, primarily through conversion to Islam, although it was also learned and spoken by Christians and Jews. Arabic became the language of administration and was the primary language of literature produced in al-Andalus; the Andalusi vernacular was distinct among medieval Arabic vernaculars in that it was used in poetry, in zajal and the kharjas of muwaššaḥāt.

A kharja or kharjah (Arabic: خرجة, romanized: kharjah, lit. 'exit' [ˈxardʒa]; Spanish: jarcha [ˈxaɾtʃa]; Portuguese: carja [ˈkaɾʒɐ]; also known as a markaz مَرْكَز 'center'), is the final couple of abyāt, or verses, of a muwaššaḥ (مُوَشَّح 'girdle'), a poem or song of the strophic lyric genre from al-Andalus. The kharja can be in a language that is different from the body; a muwaššaḥ in literary Arabic might have a kharja in vernacular Andalusi Arabic or in a mix of Arabic and Andalusi Romance, while a muwaššaḥ in Hebrew might contain a kharja in Arabic, Romance, Hebrew, or a mix.

The muwashshah typically consists of five strophes of four to six lines, alternating with five or six refrains (qufl); each refrain has the same rhyme and metre, whereas each stanza has only the same metre. The kharja appears often to have been composed independently of the muwashshah in which it is found.
