In 2019, UNESCO added Gnawa music to its Representative List of the Intangible Cultural Heritage of Humanity. The inscription recognised what anyone who has encountered the music already knows: that Gnawa — with its deep, hypnotic bass lines, cascading metal castanets, and ceremonial trance sequences — is one of the most extraordinary musical traditions on Earth. It is also one of the least understood by visitors to Morocco. This guide attempts to change that.
Origins and History
The word "Gnawa" derives from the Berber term for Black Africans — agenaw or aguinaw — though its precise etymology remains contested among scholars. The Gnawa people are the descendants of sub-Saharan Africans brought to Morocco as slaves across many centuries, primarily from the regions that today encompass Mali, Senegal, Guinea, and Sudan. The Trans-Saharan slave trade, which preceded and partially overlapped with the Atlantic trade, funnelled enslaved people northward through Morocco from at least the 10th century onward.
Enslaved in Morocco, these communities forged a distinctive spiritual practice that syncretised sub-Saharan animist traditions with Moroccan Sufi Islam and pre-Islamic Berber beliefs. The result was neither purely African nor purely Islamic but something genuinely new: a healing system that used music, colour, incense, and ritual to diagnose and treat spiritual afflictions caused by jnun (spirits) — beings that inhabit the invisible world alongside humans in Islamic cosmology.
Over centuries, the Gnawa were integrated into Moroccan society as free people, but they retained their distinctive spiritual brotherhoods (zawiya) and their role as healers. Moroccan sultans, including the Alaouite dynasty that has ruled since the 17th century, patronised Gnawa healers and incorporated their ceremonies into royal spiritual life. Today, Gnawa communities are concentrated in Marrakech, Essaouira, Fes, and Casablanca.
The Instruments
The Guembri (Hajhuj)
The guembri is the sonic heart of Gnawa music — a three-stringed bass lute with a body carved from a single block of wood (traditionally cedar or walnut) and covered with a camel-skin soundboard. The neck is a simple wooden rod; the strings are made from twisted gut or, in modern instruments, nylon fishing line. The instrument produces a deep, resonant, slightly buzzing tone — a sound compared variously to a fretless bass guitar, a sitar played below its normal register, and the purring of a large cat. The malem (master musician) plays the guembri while simultaneously singing the call-and-response phrases that structure the ceremony. Learning to play the guembri to ceremony standard requires years of apprenticeship under an established malem.
Krakebs (Qaraqeb)
The krakebs are large double castanets — pairs of iron or steel plates, roughly the size and shape of an oyster shell, connected by a metal ring. Gnawa musicians play two pairs simultaneously, one in each hand, producing a cascading, hypnotic metallic rhythm that is among the most distinctive sounds in world music. The krakebs are played by the kouyou — the chorus of Gnawa singers and dancers who accompany the malem. They also clap their hands, dance, and respond to the malem's sung phrases.
Tbel (Ceremonial Drum)
A large double-headed drum played with a curved stick, the tbel is used primarily in processional contexts — street performances and festival parades — rather than in the indoor lila ceremony. Its sound is more martial and less trance-inducing than the guembri; it announces the Gnawa presence in public space.
The Lila Ceremony
The lila (literally "night") is the central Gnawa healing ceremony — a ritual that typically runs from sunset to sunrise. It is not a concert or a performance but a spiritual event: the lila is held to heal a specific person (the moussem) who has been identified by a Gnawa diviner as suffering from affliction by a particular spirit. The healer is not a doctor in any Western sense but a spiritual intermediary, using music and ritual to bring the afflicting spirit into benevolent rather than harmful relationship with its host.
Structure
The lila proceeds through seven colour sequences, each associated with a group of spirits (mlouks). The malem plays the musical suite associated with each colour group in turn, the krakebs maintaining a hypnotic ostinato beneath. As the correct sequence is played for the spirit affecting the patient, that person enters a trance state (jedba) — a dissociative condition in which the spirit's presence is directly experienced. The trance manifests as rhythmic swaying, then more intense movement, sometimes spinning or falling. It is not frightening to those who understand its context; it is cathartic and, within the tradition's own framework, healing.
Attending a Lila
The lila is a private healing ceremony, not a tourist attraction. Visitors are occasionally invited to observe by Gnawa families who host them, but this requires a genuine personal connection — typically through a guesthouse owner, a local contact, or a cultural guide with established community relationships. If you are fortunate enough to receive such an invitation, accept with gratitude and observe with the same respect you would bring to any religious ceremony: don't photograph without explicit permission, don't talk during the music, don't touch the ceremonial objects or the patient.
The Seven Colours (Mlouks)
Each colour in the Gnawa system corresponds to a group of spirits, a set of musical pieces, specific incense, and ceremonial dress. The complete system of correspondences is complex and transmitted orally within Gnawa families; what follows is a simplified overview of the seven primary colours:
Sidi Bilal — the patron saint of the Gnawa — holds particular significance. According to tradition, Bilal ibn Rabah was an Ethiopian-born slave who became the first muezzin of Islam, chosen by the Prophet Muhammad himself to call the faithful to prayer. His story — an African slave elevated to sacred status at the founding moment of Islam — resonates deeply through the entire Gnawa spiritual framework.
The Essaouira Gnaoua World Music Festival
Each June (typically the third or fourth weekend), Essaouira hosts the Gnaoua World Music Festival — one of Africa's largest music festivals and the most important annual gathering of Gnawa music in the world. Founded in 1998 by local journalist Neila Tazi, the festival grew from a small cultural event into a four-day celebration that draws 400,000-500,000 visitors and features both traditional Gnawa performances and collaborative concerts pairing Gnawa malemat with jazz musicians, electronic producers, and world music artists from across the globe.
What to Expect
The festival operates on multiple scales simultaneously. The main stage (Place Moulay Hassan) hosts the headline collaborative concerts each evening — in recent years these have included pairings of Gnawa masters with musicians from Senegal, Mali, Brazil, and the United States. These concerts are free and open to all. Smaller stages throughout the medina host daytime performances by individual Gnawa groups — more intimate, less spectacle-oriented, and often more musically intense. Some streets in the medina become spontaneous performance spaces throughout the festival days.
Logistics
Book accommodation 3-4 months in advance — Essaouira fills completely during festival weekend and prices increase significantly. Day-trippers from Marrakech (2.5 hours by bus) are common; grand taxis from Marrakech depart from Bab Doukkala station from 6am (75 MAD per seat). The festival itself is entirely free to attend.
Gnawa in the Modern World
Gnawa music has exercised an outsized influence on global music far beyond its geographical origins. When American jazz and blues musicians began visiting Morocco in the late 1960s and 1970s — drawn partly by the country's cultural openness and partly by its association with artistic experimentation — they encountered Gnawa and recognised something familiar: the call-and-response structure, the use of music for trance and spiritual experience, the centrality of a deep bass instrument. Ornette Coleman, Randy Weston, and later Hassan Hakmoun and Maalem Mahmoud Guinia became key figures in introducing Gnawa to Western jazz audiences.
Contemporary Gnawa musicians have embraced fusion without abandoning tradition. Artists like Maalem Hamid El Kasri blend Gnawa with reggae and hip-hop. Mehdi Nassouli grafts Sufi poetry onto Gnawa rhythmic structures. The group Innov Gnawa, based in New York, brings the tradition to American concert audiences. Meanwhile, in Morocco itself, a younger generation of Gnawa musicians insists on the primacy of the lila — the healing ceremony — as the authentic core of the practice, resisting its reduction to world music performance.
Where to Hear Gnawa Music
Marrakech
- Djemaa el-Fna: Gnawa musicians perform in the square daily, typically in the afternoon and evening. The performances are tourist-oriented but feature genuine musicians and genuine instruments. Contributing 20-30 MAD to the musicians' hat is appropriate.
- Dar Gnawa (Marrakech Cultural Centre): Occasional formal concerts; check with local cultural centres and guesthouses for programme information.
Essaouira
- Place Moulay Hassan evenings: Gnawa musicians gather in the main square most evenings, particularly in summer. More relaxed and less tourist-pressured than Djemaa el-Fna.
- Gnaoua World Music Festival: June. The definitive experience — see above.
- Khamlia village (near Merzouga): A small village in the Sahara near Erg Chebbi, Khamlia is inhabited by descendants of Sub-Saharan African slaves who maintain a particularly pure form of Gnawa practice. Several families host informal performances for visitors; most desert camps can arrange a visit (150-200 MAD including tea and music). The performances here feel less polished and more spiritually serious than urban equivalents.
