We recently handled the original music score for the short horror film The Resonance—a project that asked for sound to feel as physical as the picture. Our brief: build a musical world that creeps under the skin, culminating in a possession scene that jolts from tension to violence without losing clarity or intent.

From day one we knew this score shouldn’t rely on stock risers or generic drones. The director wanted organic fear—a sense that the music was being torn, bent, and re-formed right in front of you. That pointed us toward strings (cellos and violins) as our primary instrument family, and toward a language we call mutilated strings: playable techniques recorded intimately, then pushed into unstable territory through performance pressure and bespoke processing.

We designed and recorded a library of cello and violin gestures specifically for The Resonance. Rather than simply sampling, we performed stress into the sound:

Bow pressure & sul ponticello: strained tone, glassy harmonics, and a living edge that never sits still.

Col legno & Bartók pizzicatos: percussive strikes and whip-like accents that translate as “body blows” in the cut.

Scrapes, overpressured tremolo, cluster glissandi: evolving textures that feel like a presence circling the room.

Breath-like swells: quiet, intimate crescendos designed to live under dialogue without masking.

We captured these with close mics, then mutilated them in post—granular processing, time-stretch, pitch fractures, and selective re-amping through springs and resonant plates. The result is a palette that’s unmistakably acoustic at its core yet warped enough to embody the story’s supernatural pull.

Horror scoring lives and dies on contrast. We shaped three interlocking layers so the film could pivot from dread to impact to aftershock without sonic clutter:

Textural Beds (tension engines): Low-motion clusters, beating harmonics, and barely-there tremolos that raise the room noise of the scene and keep the nervous system on alert.

Hits & Stingers (shock punctuation): Tight, chesty impacts built from col legno, detuned double-stops, and crushed tape tails. These are carved to read clearly against the film’s sound design.

Hard Movements (possession kinetics): Fast, sliding clusters and aggressive bow attacks that “grab” the frame and shove momentum forward during physical action and the possession sequence.

For the possession set-piece we built a cue that breathes with the edit and escalates in discrete stages:

Pre-tremor: a thin, icy overtone field (sul ponticello) with micro-glissandi, barely audible but constantly shifting—like the room is narrowing.

Incursion: layered tremolo cells begin to interlock rhythmically; a distant low-cello growl rises in pitch and density.

Fracture: sudden negative space—then a percussive strike (col legno + processed tail) lands exactly with the visual break.

Spiral: sliding clusters surge upward while a strobe-like pulse (bow-on-bridge) accelerates, creating a physical sense of vertigo.

Possession: we collapse the harmony into clustered unisons—several slightly detuned notes creating one massive, beating tone—then tear it apart with glissandi that mimic a body being taken over.

Aftershock: everything drops to a hollow, breathy residue; the room “remembers” what happened in a thin, metallic ring.

This structure makes the music feel inevitable without telegraphing scares. Each stage has a job, and every transition respects pacing, dialogue, and FX.

In horror, sound design and score are dance partners. We carved spectral lanes so nothing important masks:

Carved mids for dialogue, with most urgency living just above or below speech.

Transient management on hits so they read as musical shocks, not mud.

Alternates & stems (beds / pulses / impacts / gestures) to let the re-recording mixer throttle intensity in context.

We used harmony as pressure, not exposition. Small microtonal offsets create beating patterns that listeners feel more than hear. Motifs are simple but unstable—a two-note cell that can’t settle, or a rising shape that never resolves. That instability cues the body to anticipate threat, even when nothing overt happens onscreen.

The “mutilation” isn’t gore; it’s transformation:

Granular & time-domain warps turn short gestures into evolving atmospheres.

Tape wow/flutter & spectral smearing make tones feel sickly and human—perfect for possession.

Huge thanks to Paul and Sashia for entrusting me with the music for your films—your vision and trust made this score possible. Grateful to collaborate with you both.

If you’re building a horror short, trailer, or feature and want a bespoke, string-driven score that moves from whisper to possession without cliché, we’d love to talk. At Penrose Audio, we compose, record, and design music to fit your picture like a second skin—alive, unstable, and tuned to your story’s pulse.
