The Gnawa (or Gnaoua, Ghanawa, Ghanawi, Gnawi) people originated from West Africa; to be precise the ancient Ghana Empire of Ouagadougou (present day Mauritania, Senegal, Gambia, Burkino Faso and 85% of Mali (pre Gnawi/Mali Wars)).
This name Gnawa had probably originated in the indigenous language of North Africa and the Sahara Desert - the Berber language or Tamazight. The phonology of this term according to the grammatical principles of Berber is as follows: agnaw (singular), ignawen (plural).
The Gnawa are an ethnic group whom, with the passing of time became a part of the Sufi order in Maghreb.
The Gnawa population is generally believed to originate from the Sahelian region of West and Central Africa, which had long and extensive trading and political ties with the Maghreb.
While adopting Islam, Gnawa continued to celebrate ritual possession during rituals where they are devoted to the practice of the dances of possession and fright. This rite of possession is called Jedba (Arabic: جدبة). Gnawa music mixes classical Islamic Sufism with pre-Islamic African traditions, whether local or sub-Saharan.
The term Gnawa musicians generally refers to people who also practice healing rituals, with apparent ties to pre-Islamic African animism rites. In Moroccan popular culture, Gnawas, through their ceremonies, are considered to be experts in the magical treatment of scorpion stings and psychic disorders. They heal diseases by the use of colors, condensed cultural imagery, perfumes and fright.
Gnawas play deeply hypnotic music, marked by low-toned, rhythmic sintir melodies, call-and-response singing, hand clapping and cymbals called krakeb (plural of karkaba). Gnawa ceremonies use music and dance to evoke ancestral saints who can drive out evil, cure psychological ills, or remedy scorpion stings.
