If it is the real thing there is the traditional tuning of the orchestra which differs slightly from standard Western tuning. And the arrangements are highly developed.
A modern updating of this sound that keeps to the essentials of the style in exciting ways can be heard on the recent album by Jalilah's Raks Sharki. The album is called Stage Cuts.
It has all the elements described above and a pronounced rhythmic underpinning that makes it very much music for dance (but no, it sounds nothing like disco or the modern equivalent).
This is excellent music that brings out all that makes the style a joy to hear. It grooves like nothing else quite does.
Get with this one!
