The Ghazal is a poetic form consisting of rhyming couplets and a refrain, with each line sharing the same meter. A ghazal may be understood as a poetic expression of both the pain of loss or separation and the beauty of love in spite of that pain. The form is ancient, originating in Arabic poetry in Arabia long before the birth of Islam. The term ghazal is of North African and Middle Eastern origin. Its root term in Arabic is " gh-zl " and is derived from the Arabian panegyric qasida. The structural requirements of the ghazal are similar in stringency to those of the Petrarchan sonnet. In style and content it is a genre that has proved capable of an extraordinary variety of expression around its central themes of love and separation.
