The description of Turkish music is rather cursory: there are several  
descriptions. See for example Ozan Yarman, "A Comparative Evaluation  
of Pitch Notations in Turkish Makam Music".

The LilyPond text refers, I take it, to the Arel-Ezgi-Uzdilek (AEU)  
system. It does divide the major second M into 9 parts, but the minor  
second m is divided into 4; so it is 2*m + 5*M = 2*4 + 5*9 = 53 equal  
temperament. The file makam.ly, I recall, departs from E12 dividing  
the major second into 9 parts. So it should be in E108.

So I avoid using the terms "whole" and "half" tones, because the half  
tone is not in general a half of the whole tone. :-)

Also, when listing the note names as c, d, e, ..., then that refers to  
the octave numbering of major scales which I think was introduced by  
Helmholtz, possibly influenced by Romantic period centralizing CPP  
major/minor harmony.

At the Maqam World site <http://www.maqamworld.com/>, they number the  
octaves according to the minor scale. I do not know why, but perhaps  
they have never started using the Helmholtz system. So perhaps the  
notes should be named a, b, c, ... in this context.

Just mentioning it. When LilyPond expand being capable of handling  
more music outside CPP, there might be more such details pooping up.
