Dance on all sides of the Persian Gulf (“khalij” means “gulf” in Arabic), show remarkable similarities to each other.  For example, the rolling 6/8 rhythm (with its double “pick-up” on beats 5 and 6) is used in all of the areas bordering the Gulf, but very few other areas (in no other form of Iranian music, and rare in other Arab music).  Dance movements around the Gulf show similarities as well, with the emphasis on sharp quick shoulder shimmies, poly-rhythmic clapping, and minimal footwork.
