The author of this treatise on music is not known but was probably composed during the 14th century in Iran. It includes an introduction and four chapters, with depictions of musical instruments such as the ‘ud, nay, rubab, qanun, etc. The author refers to Safi al-Din al-Urmawi (d. 1284 AD) and focuses on the definition of sound, melody, rhythm and intervals with a list of twelve maqams. Each of these maqams is associated with a poem by well-known authors such as Sa’di and Anwari.
