This file tries to imitate the AUE (Arel-Ezgi-Uzdile), cf. Ozan Yarman, "A Comparative Evaluation of Pitch Notations in Turkish Makam Music”. The AUE system uses E53, 53-equal temperament, which is very close to Pythagorean tuning, The E53 tone steps are called commas, with major second M = 9, minor second m = 4, and sharp # = 9 - 5 = 4 commas. The AUE symbol # raises with 4 commas, and is not a Pythagorean tuning sharp, which causes some confusion among performers. The LilyPond implementation is not correct: it uses a multiple of E12, and does not transpose correctly: the sharp should have been divided into 5 steps. One can use E53 by Graham Breed’s regular.ly, and the MIDI will then come out correctly. And it is possible to use the SMuFL.org font with http://www.openlilylib.org/, but that is a bit more complicated. > Arabic noatation \include arabic.ly > maqam -> plural maqamat > The notation simply divides a full tonal step into 4 intervals.

This is just a hack in E24 somebody did in order to do the notation. E53 would be better, as above. The difference is to raise with with 2 commas for or lower with 3, except in Maqam Sikah Baladi [1]. 1. http://www.maqamworld.com/maqamat/sikah.html#sikah-baladi _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
