Hi, I'm Sam Pieter Janssens – aka Clairval.

I’m a composer and music producer from Brussels, Belgium, crafting original scores for film, TV, and commercials. Music isn’t just my passion, it’s my way of storytelling. Whether it's a cinematic score or an evocative ambient piece, I create soundscapes that enhance emotion and elevate visual narratives.

I live just outside Brussels with my wife and two children, where creativity flows as freely as my morning coffee.

Let’s create something unforgettable together.

From Knitting Needles to Soundtracks

It all started when I was five, drumming along to the radio with knitting needles. A few years of drum lessons later, I craved melodies too. So I spent eight years studying classical guitar. Growing up, I soaked in blues, pop, and rock from my older brother’s record collection, which inspired me to start recording my own music on a Tascam 4-track.

To bring my ideas to life, I taught myself to play keys and bass, becoming a one-man band. Sound exploration became an obsession, and over time, I turned that passion into composing for film, TV, and podcasts.

During the lockdown in 2020, I produced my own podcast series and fell in love with the process: recording, editing, composing. Now, it’s a part of what I do.

Today, I create from my home studio - my little slice of paradise - where every project starts with a spark and ends with a soundtrack.

One of my most exciting projects was composing the score for FOMO, a teenage horror feature film. That experience confirmed what I love most: bringing stories to life through music.

From reading the script to meeting the director, shaping the film’s sonic identity, collaborating with the editor, and fine-tuning every detail with the team, … It's an incredible process. And when everything finally comes together, when the music seamlessly enhances the story, that's where the magic happens.
