There aren't actually two distinct traditions, the Syrian and Ottoman theoretical traditions. Although they currently have different political organizations, there's a cultural unity stemming from centuries of being a single state. However, I've observed that Orientalists, in particular, strive to avoid mentioning the term "Turk" in this regard. I believe that the writing of notes in the Yegah key, especially in the Arab world, is a particular effort by Orientalists. By writing Arabic music in the Yegah key, and by failing to agree on the Rast key used by Turkish musicians, they are trying to create the impression that they have separate musical theories. Since my English isn't very good, I relied on the translation. I hope this is expressed correctly. Respectfully.
