In the eighteenth century Ottoman/Turkish music there are several written sources in which the notes of instrumental works are recorded. The first is the music notebook of Nâyi Osman Dede, which was written in the last quarter of the seventeenth century. The second work is Kitabu ?lmil Musiki ala vechi’l Hurufat, known as Kantemiro?lu Edvar?, which was written the first quarter of the eighteenth century. The other work is Kitab-? Musikar known as Kevserî Mecmuas? of Nayi Mustafa Kevserî, which is supposed to be written in the middle of the eighteenth century. There are over hundred instrumental pieces in Nâyi Osman Dede's notebook, three hundred fifty in Kitabu ?lmil Musiki ala vechi’l Hurufat and five hundred thirty nine in Kevserî Mecmuas?. Nâyi Osman Dede's book is in the private library and is still closed to the studies of the researchers. In this study, the instrumental pieces written in Kitabu ?lmil Musiki and Kevserî Mecmuas? were examined according to the pitches and half pitches used in the makams were determined. The determined half pitches using the makams were compared and the differences were determined. It was seen that the makams using the same half pitches could be distinguished by some differences such as tonic pitch. Half pitches were found to be the most important factor determining the makams
