'Abd al-Qadir ibn Ghaybi

'Abd al-Qadir ibn Ghaybi (b. c. 1350 - d. March 1435, Herat) was one of the greatest of the Persian writers on music. His works are of great importance in the history of Persian, Arabian and Turkish music.  

'Abd al-Qadir ibn Ghaybi was a Persian singer and musicologist, writing in Persian. 

'Abd al-Qadir came from a family of singers from Azerbaijan Maragia. At the end of the fourteenth century, 'Abd al-Qadir began his career singing in the courts of sultans. For a time, he lived at the court of the Turkish sultan, and then, from about 1393, he was associated with the court of Timur and his son Miranszaha.  He was also active in Baghdad and Samarkand  in the courts Khalil and Szahrucha.   

'Abd al-Qadir is the author of the following works on the theory of musical aesthetics: Jama al-alhan (Set of Tunes, 1405), dedicated to a discussion of the science of music and its nature and place in the religion of Islam and Arab and Persian culture; al-alhan Makasid ( Destiny tune, 1418), dedicated Timur's grandson; and al-adware Szarh (Commentary on the book of the key ).  His work Kanz al-alhan (Treasury melody) invoked the authority of later generations of artists and musicologists of the Arab world.
