Spatial Audio & Immersive Music for Gnawa: Lila Ceremony, Gnawa Fusion & Gnawa Jazz
Spatial9 Team · · Updated · 18 min read
Part of the series Spatial audio and immersive music by genre.
Key takeaways
- In a spatial Gnawa mix the guembri and the maâlem's voice sit at the centre, with the iron qraqeb ringing on both sides, the answering chorus around the listener and the warm room of a night ceremony behind.
- Because the brain sorts sounds into separate streams by pitch and direction, the deep guembri, the metallic qraqeb and the chorus stay clear when they come from different places, even when they play without pause for hours.
- Gnawa is trance music that builds slowly, so the motion should come from tempo and intensity rising together rather than from sounds flying around the room.
- The Gnawa music immersion profile scores width 4, height 3, movement 2, low-end focus 4 and space 4 out of 5.
Gnawa is the spiritual music of the Gnawa brotherhoods of Morocco, with close relatives in the diwan of Algeria. Its roots lie with people from sub-Saharan West Africa who were brought north across the Sahara over many centuries, many of them enslaved, and who blended their own traditions with Sufi Islam. The music grew up in cities such as Marrakech, Essaouira, Fez and Tangier. Its heart is the guembri, also called the sintir or hajhouj, a three-stringed lute with a long neck and a body covered in camel skin, played by a master musician known as the maâlem. Around him, musicians clash the qraqeb, pairs of heavy iron castanets, and sing a chorus that answers his calls. Large tbel drums lead the opening procession. The central ritual is the lila, a night-long ceremony of healing and trance in which each family of spirits, the mlouk, is called with its own songs, colours and incense. From the late 1960s visiting jazz musicians began to seek it out, and in the 1970s groups such as Nass El Ghiwane brought Gnawa sounds into popular music. The Gnaoua and World Music Festival in Essaouira began in 1998, and in 2019 UNESCO added Gnawa to its list of intangible cultural heritage. Gnawa suits spatial audio because the music is played in a circle and the room is part of the ritual. This guide covers how spatial audio for Gnawa music works, where to place each element and how to make an immersive Gnawa mix. For the basics, see what spatial audio is.
Why Gnawa music works in spatial audio
Gnawa is built on a few strong layers that repeat for a long time. The guembri plays deep, looping bass phrases with a buzzing, percussive attack. The qraqeb lock into a fast, clattering triplet pulse. The maâlem sings a line and the chorus answers. Over many minutes the tempo rises, the qraqeb get louder and the dancers move toward trance. In stereo the guembri and the iron castanets fight for the same space, and the metal can bury the bass. In an immersive mix the guembri holds the centre, the qraqeb surround it from both sides and the room gives the long build somewhere to grow.
The rule: the guembri in the middle, the iron all around it. Anchor the bass lute and the voice at the centre, spread the qraqeb players in a wide arc and set the circle inside a warm room where the night can unfold.
Immersive music for Gnawa music: what listeners hear
- A bass voice in the middle of the circle. The guembri sits close and centred, so its deep, buzzing phrases feel like they come from the floor beneath you.
- Iron on both sides. The qraqeb clatter from left and right, wrapping the listener in a bright, steady pulse without masking the guembri.
- Call and answer around you. The maâlem sings from the front and the chorus answers from the sides, so every phrase becomes a conversation in the room.
- A slow climb toward trance. As the tempo and volume rise, the whole circle seems to lean in, with no need for sounds to move around the space.
Where to place each element in a Gnawa music mix
| Element | Position | Height | Why it works |
|---|---|---|---|
| Maâlem voice | Front centre | Ear level | The master's call that leads each song |
| Guembri | Centre | Low | Deep bass phrases that anchor the trance |
| Qraqeb left | Front left | Ear level | One side of the iron castanet pulse |
| Qraqeb right | Front right | Ear level | The other side of the castanet pulse |
| Response chorus | Left | Ear level | Voices answering the maâlem's call |
| Handclaps | Right | Ear level | Accents that lift the groove |
| Tbel drums | Behind left | Ear level | The opening procession and big accents |
| Sax and keys | Behind right | Ear level | Colour in Gnawa jazz and fusion |
| Ceremony room | Behind | Raised | A warm courtyard around the circle |
The psychoacoustics behind Gnawa music placement
Every position in the table above follows how the ear and brain locate sound. Here is the reason behind the main choices for Gnawa.
- Guembri stays centred. The ear finds almost no direction in frequencies below roughly 80 to 100 Hz, so the deepest part of the guembri gains nothing from being spread. Keeping it centred holds the trance steady (Blauert).
- Qraqeb and guembri in different places. The brain groups sounds into streams by pitch, timing and direction. This is auditory stream segregation (Bregman). Setting the bright iron apart from the low lute lets the ear follow both for hours without fatigue.
- A build that seems to approach. Listeners hear sounds that grow louder as moving closer, and they overestimate how near a rising sound has come. This is the looming effect for rising intensity (Neuhoff). The long crescendo of a Gnawa song already carries this sense of motion, so it needs no panning.
- A room with side reflections. Early reflections arriving from the sides make a sound feel wider and more enveloping. This is spatial impression from early lateral reflections (Barron and Marshall). Clear side reflections make the circle feel like a real courtyard while keeping the qraqeb crisp.
The immersion profile for Gnawa music
Width scores 4 because the qraqeb players and chorus form a wide circle around the maâlem. Low-end focus also scores 4: the guembri is a true bass instrument, and its deep plucked lines carry the whole ceremony. Space is 4, since the lila takes place in a room or courtyard full of people, and that room shapes the sound. Height is 3, from chanting voices and ringing iron rising into the roof of the space. Movement is 2, because the motion comes from a slow, steady build in tempo and intensity rather than from sounds travelling around the listener.
Tips for an immersive Gnawa music mix
- Anchor the guembri. Keep it centred and close, with its buzz and percussive slaps clear, so the trance always has a floor.
- Split the qraqeb. Place the castanet players on both front sides so the iron pulse surrounds the guembri instead of covering it.
- Let the chorus answer. Put the response voices to the sides, a little further back than the maâlem, so call and answer are easy to follow.
- Let the build do the moving. Keep the players in place and let the rising tempo and volume carry the listener toward trance.
- Use a warm, lived-in room. A moderate courtyard reverb suits Gnawa, but keep the low end of the reverb short so the guembri stays tight.
Gnawa music styles: Lila ceremony, Gnawa fusion and Gnawa jazz
The core placement holds for every style here: the guembri and voice at the centre, the rhythm spread around them. What changes is the size of the group, the amount of electric and electronic sound and how much room the style needs.
Lila Ceremony
The lila, sometimes called the derdeba, is the traditional night ceremony of the Gnawa. It usually opens with a procession led by tbel drums and qraqeb, then moves into the sung sections played on the guembri, with each group of spirits called by its own repertoire, colour and incense. Dancers may enter trance as the music grows faster and louder, and the ceremony can last until dawn. Seat the guembri and maâlem in the centre, the qraqeb in an arc on both front sides and the chorus to the sides, with the tbel behind for the procession. A warm, natural courtyard room suits the style.
Gnawa Fusion
Gnawa fusion blends the guembri and qraqeb with rock, reggae, funk and electronic music. In the 1970s Moroccan groups such as Nass El Ghiwane drew on Gnawa rhythms, and later bands such as Gnawa Diffusion, formed in France by musicians of Algerian origin, mixed it with reggae and rock. Keep the guembri and lead voice in the centre, with the bass guitar, if there is one, sitting right underneath the guembri rather than competing with it. Electric guitars and keys can sit to the sides, qraqeb front left and front right, and effects or electronic loops behind.
Gnawa Jazz
Gnawa jazz grew from meetings between Gnawa masters and jazz musicians. The pianist Randy Weston lived in Tangier in the late 1960s and worked with Gnawa musicians for decades, and the saxophonist Pharoah Sanders recorded The Trance of Seven Colors with Maâlem Mahmoud Guinia in 1994. Later projects, such as those of the guembri player Majid Bekkas, continued the meeting. Keep the guembri and the maâlem's voice centred and the qraqeb on the front sides, with the saxophone or piano behind right or to the side so it can answer the chorus. A concert hall with clear reflections suits the music.
Related traditions such as the Algerian diwan and the trance music of other North African brotherhoods follow the same idea: keep the lead voice and lute in the centre, the rhythm in a circle around them and the room around the listener.
Dolby Atmos and object-based mixing for gnawa
Dolby Atmos mixes gnawa as a channel bed plus objects placed anywhere in the room. The bed holds the heavy guembri and tbel drums, while objects allow precise placement of the maâlem and qraqeb. Most listeners will hear a binaural headphone render on Apple Music, Tidal or Amazon Music. Spatial9 helps plan placements for every format so the mix translates well. The channel bed provides the foundation for the trance, and the objects create the wide circle of musicians around the listener.
How the Atmos plan differs from the placement map. This Dolby Atmos plan differs from the Ambisonics map to keep the main stage in front. The map placed the guembri behind, but here it sits in the front bed to anchor the low end. The qraqeb were placed wide to the sides, but we pull them forward to act as main leads alongside the maâlem. The tbel drums and sax were behind, but we move them into the front and sides to preserve focus. The ceremony room remains a full surround bed.
Beds and objects for each gnawa element
| Element | Atmos role | Where it plays in 7.1.4 | Binaural mode | Why |
|---|---|---|---|---|
| Maâlem voice | Object | Ear level, front of the room, centre (X 0, Y 0.8, Z 0) | Near | The master vocal anchors the front stage. |
| Guembri | Bed | Centre plus LFE (C + LFE) | Off | Bass lute needs solid low end in the bed. |
| Qraqeb left | Object | Ear level, front of the room, left (X -0.3, Y 0.6, Z 0) | Mid | Iron castanets lead the trance from the front left. |
| Qraqeb right | Object | Ear level, front of the room, right (X 0.3, Y 0.6, Z 0) | Mid | Iron castanets lead the trance from the front right. |
| Response chorus | Object, medium size | Ear level, middle of the room, far left (X -0.8, Y 0.2, Z 0) | Mid | Answers the master from the left side. |
| Handclaps | Object, small size | Ear level, middle of the room, far right (X 0.8, Y 0.2, Z 0) | Mid | Lifts the groove from the right side. |
| Tbel drums | Bed | Front left and right (L/R) plus LFE | Off | Large drums need low end support in the bed. |
| Sax and keys | Object, small size, moving | Ear level, front of the room, right (X 0.5, Y 0.5, Z 0). Moving: Drifts across the right side during the solo, ending at ear level, front of the room, far right | Mid | Adds movement and colour to the fusion arrangement. |
| Ceremony room | Bed | Whole 7.1.2 bed | Far | Wraps the listener in the courtyard acoustic. |
Dolby Atmos settings for gnawa
- LFE. Route the guembri and tbel drums to the LFE channel within the bed. Objects have no LFE send, so low end placed as an object relies entirely on the listener's bass management.
- Object size. Keep the maâlem and qraqeb objects set to point or small sizes. This maintains their sharp focus in the front stage and prevents the iron castanets from smearing across the speakers.
- Height use. Reserve the height channels for the ceremony room reverb and occasional overhead accents. Dry rhythmic parts placed fully overhead lose their impact on headphones and in stereo fold-downs.
- Binaural render. Set the guembri to off to keep the bass solid. Use near for the maâlem, mid for the qraqeb and chorus, and far for the ceremony room bed.
- Stage depth. Pull the qraqeb slightly off the front wall. This adds depth to the gnawa circle and stops the mix from sounding like a flat wall of sound.
Gnawa across immersive formats
| Format | How it carries sound | What it means for gnawa |
|---|---|---|
| Dolby Atmos | Hybrid: a 7.1.2 channel bed plus up to 118 objects placed with X, Y and Z metadata | Dolby Atmos is a hybrid format using a channel bed for the guembri and objects for the qraqeb and vocals. |
| Sony 360 Reality Audio | Object-based, built on MPEG-H 3D Audio: every sound is an object on a sphere | Sony 360 Reality Audio has no channel bed, so every gnawa element becomes an object placed on a sphere around the listener. |
| MPEG-H 3D Audio | Channels, objects and Higher Order Ambisonics in one stream, with optional listener control | MPEG-H 3D Audio carries channels and objects, allowing listeners to adjust the level of the maâlem or chorus if permitted. |
| Auro-3D | Channel-based: a height layer above 5.1 or 7.1, with an optional overhead channel | Auro-3D uses fixed height channels rather than objects, so the gnawa ceremony room reverb is routed to the upper speaker layers. |
| Eclipsa Audio (IAMF) | Channel-based and scene-based (Ambisonics) audio elements; no objects | Eclipsa Audio uses IAMF, which lacks audio objects, so this gnawa Atmos mix must be rendered to channels or Ambisonics first. |
| Ambisonics | Scene-based: the whole sound field, decoded to any speaker layout or to headphones | Ambisonics captures the entire gnawa sound field as spherical harmonics, decoding the circle of musicians to any speaker layout or headphones. |
| ADM BWF | Open exchange file (ITU-R BS.2076 metadata in a BW64 file) for channels, objects and scenes | The final gnawa mix is delivered as an ADM BWF file, containing all channel and object audio alongside spatial metadata. |
Delivery checklist for a gnawa Dolby Atmos release
- Master file. ADM BWF at 48 kHz and 24-bit, with no more than 128 channels: a 10-channel 7.1.2 bed plus up to 118 objects.
- Loudness. Integrated loudness no higher than -18 LKFS and true peak no higher than -1 dBTP, measured to ITU-R BS.1770.
- Binaural metadata. Set Off, Near, Mid or Far for every bed and object. Masters with everything left on Off are rejected.
- Re-renders. Listen to the 5.1, stereo and binaural re-renders before delivery, because most people will hear one of them.
Check the binaural render to ensure the guembri remains solid and the qraqeb do not become harsh on headphones.
How to make immersive Gnawa music from stereo
Spatial9 can create spatial audio from a stereo track in a few steps:
- Upload your stereo master or your stems.
- Spatial9's AI separates and places each part, pulling the guembri, qraqeb, chorus and lead voice apart even from field recordings of a ceremony, and setting the castanets around a centred guembri.
- Preview it in binaural on headphones.
- Export Eclipsa Audio, ADM, binaural or Ambisonics.
- Publish a video. Create a YouTube-ready video with your immersive audio and publish it directly.

Frequently asked questions
Does this guide cover Lila Ceremony, Gnawa Fusion and Gnawa Jazz?
Yes. The lila ceremony seats the guembri and maâlem in the centre with qraqeb in an arc and a warm courtyard around them. Gnawa fusion adds bass, guitars and loops around a centred guembri. Gnawa jazz brings in saxophone or piano behind and to the side, inside a concert hall.
Can I make a Gnawa music mix in Dolby Atmos or Eclipsa Audio?
Can I make a gnawa mix in Dolby Atmos? Yes, Dolby Atmos is excellent for gnawa. You can use the bed for the heavy guembri and tbel drums, and objects for the maâlem and qraqeb. Remember that Dolby Atmos and Eclipsa Audio are separate deliveries, as Eclipsa uses IAMF and has no objects. Also, Apple Music applies its own spatial renderer to the Atmos file, so its headphone result can differ from the Dolby binaural render and must be checked separately.
Should gnawa elements be beds or objects in Dolby Atmos?
Should gnawa elements be beds or objects in Dolby Atmos? The low-end foundation must use the bed. The guembri and tbel drums belong in the channel bed with an LFE send to keep the bass solid. The ceremony room reverb also works best as a full surround bed. The maâlem, qraqeb, chorus and handclaps should be objects. This allows precise placement in the room and keeps the iron castanets clearly separated from the deep bass lute.
Does a gnawa Dolby Atmos mix also work for Sony 360 Reality Audio and MPEG-H?
Does a gnawa Dolby Atmos mix also work for Sony 360 Reality Audio and MPEG-H? Not directly. Sony 360 Reality Audio is built on MPEG-H 3D Audio and is entirely object-based. It has no channel bed, so the guembri and ceremony room bed from your Atmos mix must be converted into objects. You will need to create a separate mix using the specific tools for Sony 360 Reality Audio to place the gnawa circle correctly on its sphere.
Is spatial audio good for Gnawa music?
Yes. Gnawa is played in a circle, with a deep lute, iron castanets and voices that answer each other over a long build. Spatial audio lets each layer keep its own place and puts the listener inside the circle rather than in front of it.
Where should the guembri go in an immersive Gnawa mix?
Put the guembri in the centre, close to the listener and low. Its deepest notes carry little direction, and the trance depends on its pulse feeling steady and solid.
How loud should the qraqeb be?
The qraqeb are loud in a real ceremony, but in a mix they can mask the guembri. Splitting them to both sides and taming their harshest high frequencies keeps them driving without tiring the ear.
How is Gnawa music different from desert blues in spatial audio?
Gnawa centres on the bass guembri, iron castanets and a chorus in a ritual room, so it suits a circular layout with a solid low centre. Desert blues is built around electric guitars, bass and hand drums on a band stage, so it suits a wider front layout with guitars on both sides.
Can I convert an old Gnawa field recording to spatial audio?
Yes. Spatial9 uses AI to separate the guembri, qraqeb and voices from a stereo or mono recording. Separation is never perfect with crowded ceremony recordings, so keep the layout simple and the room moderate.
