"The music of the Souassa, usually, although incompletely, labelled "Chleuh" (Chleuh meaning any Berber whose language is Tachelhit) is not a tribal manifestation, but a regional one, like the music of the Djebala. The Souss (inhabitant: Soussi; plural: Souassa) is the region of southwestern Morocco which stretches roughly from the Atlantic Ocean to the upper Draa Valley, and from the Grand Atlas to the Anti-Atlas. The larger troupes of Soussi musicians are often ambulatory, and dancers generally accompany them, assisted by the players themselves, who are adept at performing the dance steps while they play on guinbri or rebab. The combination of this ensemble is as follows: three guinbris, one rebab, one bendir and one nagous. The Aoulouz from Taroudant is very clearly a dance, with its series of false endings, but each piece has the same form: a vocal prelude which gives way to a dance of increasing tempo in which the instruments gradually replace the voices."
