about Komas and accidentals
I am trying to understand turkish notation and something would like to have confirmation (or explanations) about this :
the note "MAHUR" should be slightly higher than a Fa# in occidental notation ? or exactly the same ?
thanks for any help

In arabic notation, mahur is natural Si.
In turkish notation (where rast is a Sol), mahur is a Fa + 5 komas, which means indeed slightly higher than Fa#.
Why 5 komas and not a Fa#.
I'll take the exemple of mahur makam, which is a transposition of cargah scale on rast:
Cargah (turkish notation, below numbers of komas between each notes of the scale):
Do - Re - Mi - Fa - Sol - La - Si - Do
9 9 4 9 9 9 4
Mahur scale
Sol - La - Si - Do - Re - Mi - (Fa+5 kommas =mahur) - Sol
9 9 4 9 9 9 4
A tone in turkish theory is 9 komas, but you have to know a bemol or diese is 4 komas, and not 4,5.
So to keep the intervals of komas number in the transposed scale, the fa is slightly higher than a Fa#: 9 komas higher than Mi and 4 komas lower than
sol.

Thanks
But if I consider the Cargah scale
Do - Re - Mi - Fa - Sol - La - Si - Do
9 9 4 9 9 9 4
Do notes correspond to the occidental DO major scale or not ?
Do Re Mi Fa sol la si do
=9-9-4.5-9-9-4.5 ?

No they don't correspond exactly, as the occidental (equal temperament) whole tone is 200 cents and the semitone is 100 cents, while the Turkish
tanini is 204 cents (9 commas) and the bakive is 90 cents (4 commas). So the difference in the 'semitone' is a fair amount (10 cents), while the
difference in the 'whole tone' is not much (4 cents). Not that my ear can hear them - they both sound the same to me!

Maybe you could download a tuning program like AP Tuner and check if there is the setting you need.

I just do it in fourths by ear, starting with the second string which I do first with a tuner. Perhaps using the Pythagorean setting on the AP Tuner
program would work?
