FILM & MEDIA COMPOSER · SOUND DESIGNER · BRUSSELS
Music that gives
the image an interior life.
Film and media composer and sound designer based in Brussels, Belgium, Yannis Koser creates original music, sound design and immersive audio for film, documentary, games, installations and visual media, with international remote collaboration available.
A DISTINCTIVE MUSICAL LANGUAGE
Clarity for the project.
Space for the unexpected.
Yannis Koser approaches composition as a meeting point between structure, sensation and story. The process begins with the project’s emotional centre, then develops a musical language that can support the image without merely describing it.
Film and media scoring
A musical direction shaped in dialogue with image, rhythm, silence and dramatic intention.
Sound design
Original sounds, textures, atmospheres and transitions shaped around the identity of the image.
Games & interactive
Music and sound for exploration, fantasy worlds, interactive media and narrative environments.
Immersive / installations
Sonic environments for cultural, spatial and sensory experiences.
Artistic collaboration
Responsive collaboration with filmmakers, visual artists, studios and cultural projects.
SOUND DESIGN
Sound becomes
part of the world.
Alongside composition, Yannis develops sound design that gives images, spaces and interactions their own acoustic identity. The approach remains musical and narrative: every texture, atmosphere and transition serves the experience as a whole.
Original sound creation
Purpose-built sonic material shaped for the project rather than drawn from a generic palette.
Textures & atmospheres

Immersive & interactive sound
Responsive sound worlds for installations, digital media and interactive experiences.
GAMES & INTERACTIVE
Music for worlds
waiting to be explored.

Six spaces.
Six sonic identities.
For a confidential project developed for an oceanographic museum, Yannis created six original soundtracks, each conceived for a distinct exhibition zone.
The music was designed to accompany spatial progression, deepen immersion and support the emotional perception of the marine world without competing with the visitor experience.
