Abd al-Aziz b. Abd al-Q?der-e Mar?ghi and his innovations in music (Based on his Naq?vat al-adv?r and other writings)

Following the Timurid decline, Abd al-Aziz b. Abd al-Qāder of Marāgheh left his birthplace, Herat, for Bursa and joined the court of the Ottoman Sultān Mohammad b. Morād, presenting him with his essay, Naqāvat al-advār on music. Even though the general topics that Abd al-Aziz has stated in this essay are taken from his father’s tracts, there are useful explanatory notes here and there in his own essays. Additionally, in this book he has made mention of some of his innovations. For instance, he speaks of two “sho’beh” (literally, branch) that he has invented calling them “shāhi” and “safā”. We have found a manuscript of his in which he has presented, in musical notation, a song in the safā branch, in the dawr-e mokhammas (literally, fivefold round) using letters and numbers.
In this article, assumptions have been suggested with a view to finding the rhythm of this song and the way syllables are connected to the dawr-e iqā’i (literally, rhythmic cycle)
