Abdulbaki Nasir Dede

Abdülbâkî Nâsır Dede was a composer from the Ottoman Empire. At the request of Selim III, Abdülbâkî authored the treatise Tedkîk-u Tahkîk (تدقيق و تحقيق; “Examination and Verification”), in which he outlined the distinguishing characteristics of 136 makams and 21 usuls, and transcribed and published the compositions of the sultan. Among Abdülbâkî Dede’s most notable works are his ayins in the Acembuselik, Isfahân, and Şevkitarap makams, as well as his translations of Menâḳıbü’l-ʿârifîn and Şerh-i Şâhidî. In another work, titled Tahrîrîye, he described the musical notation system he personally invented.
