Gareth Cousins Music

The soundtrack you hear in a cinema isn’t just music - it’s the audible DNA of the era that created it. Every shift in film scoring - from the silent era of piano or organ accompaniment to the immersive Dolby Atmos swirl of a space disaster - mirrors the news headlines, the street fashion, the political mood and the available technology of its moment.

In the alchemy of producing film, TV, and game music, sound isn't just heard - it's felt. For over 40 years, since my first days at Abbey Road Studios in 1986, I've chased a philosophy that boils down to two elemental forces: moving air and moving electrons. These aren't abstract concepts; they're the raw, unpredictable energies that breathe life into scores, transforming sterile digital canvases into immersive, soul-stirring soundscapes.

If you scroll through the end credits of almost any big film, you’ll spot the usual music roles: composer, orchestrator, conductor, music editor… and then, usually tucked away near the bottom: Score Mixer. To a lot of filmmakers — and even some musicians — it still sounds a bit mysterious. The composer writes the music, the orchestra plays it… so what exactly does a score mixer do?

Most people see “Music Editor” in the end credits and assume it’s just someone chopping music to fit the picture. Even colleagues in the industry sometimes think the same. But after years working on major films and TV, I can tell you this is one of the most pivotal – and misunderstood – roles in post-production.

Here’s why the glorious madness of daring to climb is the only thing that lasts when everything else turns to dust. From Abbey Road to mixing award-winning scores for Notting Hill, Gravity and Our Planet, my career has been one long climb on a rope that’s always burning beneath me — a metaphor I first found in a 1978 Genesis song.
