PlayStation Marathon – Developer Insights: Music of Marathon | PS5 & PC Trailer

Step inside the sonic world of Marathon, the upcoming sci-fi extraction shooter from Bungie. Released on February 19, 2026, this "Developer Insights" video features Siddhartha Barnhoorn, the composer for Marathon, as he discusses the unique creative process behind building the game's high-tech, yet deeply human, score [00:03].

In this 4-minute featurette, Siddhartha explores how the music reflects the game's core themes: the sacrifice of the human body for a machine shell, the mysterious history of the planet Tau Ceti IV, and the blend of high-tech "neon" aesthetics with "crusty," decaying environments [00:53].

🌟 Section 1: The Soul of the Machine

Unlike traditional story-driven games, Marathon does not have a central protagonist. Instead, the music is designed to tell the story of the world itself.

Key musical concepts include:

• World as the Hero: The composer explains that there is no "hero's theme"; the music serves as the theme for the planet Tau Ceti IV [00:32].

• The Human Voice as Code: Siddhartha uses the human voice to represent the "soul" that remains after a Runner relinquishes their body. He transforms vocal recitations into playable instruments that sound like digital transmissions or leftovers from a vanished colony [01:13].

• Organic vs. Mechanical: The score is inspired by natural environments filled with "mechanical bugs" and lab escapes, creating a soundscape of "creaks and whispers" [01:48].

🎹 Section 2: Prepared Instruments & Expressive Tools

The video highlights the specific physical and digital tools used to create Marathon's distinct sound.

Creative tools and techniques:

• The Prepared Piano: Siddhartha demonstrates a piano modified with "poster tac" (putty) on the strings to create muted, percussive, and distorted colors from an acoustic source [02:02].

• Acoustic Roots of High-Tech Sound: By using mechanical distortion and human performance on acoustic instruments, the team built a "very high-tech score" that still feels grounded and tactile [02:42].

• The Osmose Controller: Siddhartha showcases the Osmose, an MPE (MIDI Polyphonic Expression) controller that allows for extreme finger-based expression and sensitivity not possible on a standard piano [03:05].

🎯 Section 3: Painting with Feelings

The ultimate goal of the Marathon score is to find emotion in every digital and mechanical sound. Siddhartha describes his process as "painting with feelings" [03:33], ensuring that even the most high-tech environments have a resonant, emotional core.
