An Assessment on ？āli？ Nābī's Work of al-Falsafa al-Mūs？？ī

？āli？ Nābī (d. 1914) is a person who lived in the last periods of the Ottomans and is a medical graduate and interested in Turkish music. In 1910, he received a work called al-Falsafa al-Mūsi？ī (Philosophy of Musica). In this study, the effects of music on the human soul, music history, and musical understanding in the Ottoman period were found. Throughout history, many musical compositions have been received and reflected some philosophical thoughts. But an independent study of philosophy and music is not found before the 20th century. For this reason, ？āli？ Nābī's al-Falsafa al-Mūsi？ī work is remarkable in terms of its title. There are brief explanations about various issues in the work but the most important issue that attracts our opinion is the musical perception of the period. Because ？āli？ Nābī, as a witness at that time, thinks that music has been neglected for a long time in the Ottoman Empire. This is the reason why he has already taken him to a work. In this article, it has been tried to be given to today's musical literalism. Summary: ？āli？ Nābī was born on May 5, 1886, in Istanbul Yedikule. After his primary and secondary education, he started the Military Medicine Faculty in Cengelkoy on March 13, 1901. He graduated in 1911 after having studied for a total of ten years here.

He died at the age of twenty-eight in 1914 after having practiced medicine in several different regions. ？āli？ Nābī, who died at a young age, has two works that arrive present days. One of them is the graduation thesis named Mental Illnesses and Bel-Air Hospital in the Twentieth Century. In this work that he published in 1911, he made suggestions about the architectural works to be done in this area by making use of some of the examinations in Switzerland Bel-Air Bamarhanesi where he served as an assistant for a while. The other work, which is also the subject of our work, is named al-Falsafa al-Mūsi？ī(Philosophy of Musica). Al-Falsafa al-Mūsi？īis composed of thirty-two pages. The first fascicle, which is the subject of our work, is the only known number of this work that planned to be published as monthly magazines. This work is written to explain the subjects of music and philosophy. But this work could not continue because of ？āli？ Nābī’s participation in the Balkan Wars after his graduation and later his death at a young age. Al-Falsafa al-Mūsi？īconsists of three parts, one of which is the introduction part. Under the heading entitled "Medhal", the cultural and musical
