Traditional Moroccan Berber music can be categorised into collective and professional music.
In collective music, men and women from entire families or villages participate in dances such as the ahwash and ahidus.  A prayer is chanted at the beginning, followed by a response from a chorus of dancers. Accompanied by drums (bendir) and flutes (ney), dancers dance in a ring around the musicians.
Led by an amdyaz or poet, groups of usually four professional musicians (imdyazan) travel across the region to perform in various villages.  The amdyaz recites improvised poems about current national and world affairs. His fellow musicians accompany the poem with a drum, a single-string rebab and a double clarinet.
A Shluh Berber variant of professional music is performed by rways, led by a rays or raiss. A rway orrwai performance starts with the astara, an instrumental session on the rebab or wtar, followed by the tambourine and flute. The astara sets the basic notes of the melody.  The middle section consists of sung poetry (amarg), a choreographed overture (ammussu), a lively song (tamssust), and dance (aberdag). The tabbayt marks the final part, in which the rhythm first accelerates and then ceases abruptly.
Famous Moroccan Berber musicians include Ammouri Mbarek, a singer and songwriter active since the 1960s and considered the "John Lennon" of the Berber world, and Najat Aatabou, a singer whose debut cassette, "J'en ai Marre", sold an unprecedented half-million copies in Morocco. The Master Musicians of Jajouka tour internationally and have collaborated with Brian Jones of the Rolling Stones andWilliam S. Burroughs.
