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.

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].
