Apologies for the bad picture but this evening I encountered this piece on pages 148-149 of the Nouhbe-i-elhan book:
the usul is Devr-i Kebir for sure, with my limited knowledge of such things I would say the makam is Muhayyer Sünbüle but I may very well be wrong, and I have no idea who the composer is. Unfortunately I am unable to read Ottoman.
Would anybody know and be able to help ? I would be very grateful.
