Stam,

Is there some literature about the mathematics of Arabic music? Because I'm completely clueless in this area. I understand that in Arabic scales some tones are detuned half a semitone. What I don't understand is how you can play chords after that. A C-chord would sound as a different chord type as a D-chord because the intervals between the notes would be different from each other.

Vquestor,

Thanks for reminding me. The QY22 is not XG but the QY70 and QY100 are added to the list.
