A spatial score is a working document that shows how sound unfolds across a place and over time. It connects audible events to rooms, visitor routes, media and moments of silence so that the project team can discuss them before the final system is installed.
Acoustic blueprinting establishes the broader listening strategy. Once the role and priorities of sound have been agreed, the spatial score turns them into a plan that can guide composition, media planning, system design and on-site tuning.
A musical score organises musical material over time. A spatial score works at the scale of the whole environment and can include music, voices, ambience, interaction, media audio, physical sound sources and silence.
Consider a recorded voice in an exhibition. Up close, visitors listen to its words. From the corridor, its location may matter more than its content: the voice can draw attention towards a room or keep that room present after visitors move on. The recording has not changed, but its function changes with the listener’s position.
A spatial score makes that change visible. Depending on the project, it may take the form of a timeline, floor plan, matrix or a combination of several views. It usually records:
These dimensions help a team identify conflicts before production. They also show where recurring material can connect parts of a route and where a transition should be carried by silence rather than another sound.
The process begins with the listening strategy established during acoustic blueprinting and with the current spatial plan. The score then develops through four steps.
The score remains a working document throughout the project. Early versions may contain broad zones and provisional timings. Later versions can identify files, behaviours, playback routes and test conditions. The level of detail should follow the decisions the team needs to make.
A score is therefore useful even when visitors do not follow one fixed sequence. Interactive and generative systems still have a temporal logic: conditions for when something may happen, how long it lasts and what it may overlap with.
An 18-minute incident unfolds across several buildings and rooms of a former coal mine in Beringen. Visitors hear machinery, voices and alarms directly, from a distance or before reaching their source. The spatial score connects one timeline to many listening positions.
The permanent exhibition at the House of History Bonn contains more than sixty media exhibits in an open environment. The score coordinates interface sounds, media audio, modular music, room tones and acoustic zones so the exhibition remains legible.
Luxembourg Pavilion at Expo 2020 Dubai
Six orchestral compositions unfold in synchrony across the pavilion. Each chapter has its own theme, while a shared key and temporal structure connect the musical worlds throughout the route.
Luxembourg and German Pavilions at Expo 2025 Osaka
Musical ideas return in different forms as full themes, harmonic colours, transitions and interaction sounds. The score allows these variations to form one identity without requiring every zone to sound the same.

Sound, physical movement and visual media form a continuously changing installation. The score helps several streams of information coexist without losing rhythm or clarity.
Sound Scenography is the wider practice within which spatial scores are developed. Acoustic Blueprinting establishes the earlier listening strategy and determines whether a spatial score is needed.
Spatial Audio provides techniques for placing and moving sound, but the score determines where those techniques serve the visitor journey. Spatial Audio Formats and Methods and Spatial Audio Systems and Renderers explain how the spatial information is carried into playback. Spatial Audio Production Workflows describes how the score is tested, installed and tuned at the site.
What is a spatial score?
A spatial score is a working document that maps how sound unfolds across time, architecture, media and visitor movement.
Is it the same as a musical score?
No. A musical score organises musical material. A spatial score may include music, but it also covers voices, ambience, interaction, media audio, physical sources and silence throughout an environment.
How is a spatial score different from acoustic blueprinting?
Acoustic blueprinting defines the overall listening strategy and project requirements. The spatial score is a specific planning document that translates part of that strategy into spatial and temporal relationships.
How is a spatial score different from spatial audio?
Spatial audio describes techniques for positioning and moving sound. A spatial score records when, where and why those techniques are used within the experience.
Does a spatial score always need a timeline?
It needs a temporal logic, but not necessarily one fixed sequence. A plan, matrix or state diagram may be more useful for interactive and generative work.
When should the score be developed?
It should begin while architecture, scenography, media planning and visitor flow can still change, then remain in use through production and on-site tuning.
We develop spatial scores that give project teams a shared view of how sound, architecture, media and visitor movement work together.
