This album is mostly taqasim but each one starts with a short segment of a repetoir piece, like the Bayati is of course the al-Aryan samai but just
the first part. Is this segment of Saba part of a bigger piece that anyone knows?
I think it's a variation of one of the "standard" dawalib (sing. "doulab"), for the maqam. A dulab is composed/standard instrumental introduction
that can be used before ANY song or piece in that corresponding maqam. I have attached a score of the standard "Dulab Saba." This one is probably
just "adjusted" for non-4/4 time.
