Horror (as a musical style) is music deliberately crafted to elicit fear, dread, and anxiety. It emphasizes tension, surprise, and the uncanny through dissonant harmony, destabilized rhythm, and disturbing timbres.
Whether in film, television, games, theater, or concert works, horror music often uses clusters, tritones, micro-intervals, extended instrumental techniques, and sudden loud/quiet contrasts. Sound design is integral: tape manipulations, low-frequency rumbles, unsettling field recordings, and analog or modular synth textures blur the line between score and sonic environment.
Above all, the aim is psychological—guiding the audience’s anticipation and startle responses to produce a sustained sense of terror.

Romantic and late-Romantic concert music cultivated a taste for the macabre and the uncanny (e.g., Berlioz’s Symphonie fantastique, Liszt’s Totentanz). Early modernist techniques—atonality, serialism, clusters, and novel timbres—offered new ways to depict dread and alienation that would later be absorbed into screen scoring.
With the rise of synchronized sound, Hollywood’s first horror talkies (e.g., Universal’s Dracula, Frankenstein) established orchestral scoring conventions for fear: minor-mode melodies, lower-register orchestration, pipe organ associations, and shock accents. These scores drew on late-Romantic harmony while experimenting with silence and texture to magnify on-screen terror.
Composers such as Bernard Herrmann advanced the language of horror through stark orchestration (e.g., Psycho’s all-strings score), obsessive ostinati, and dissonant intervallic cells. Filmmakers also licensed contemporary avant-garde concert pieces (Penderecki, Ligeti) whose clusters and extended techniques became sonic shorthand for the eerie and uncanny.
Low-budget horror unlocked a more minimal, electronic approach: John Carpenter’s analog synth ostinati (Halloween) and Italian group Goblin’s prog-horror textures (Profondo Rosso, Suspiria) defined a lean, hypnotic idiom. Orchestral bombast persisted (Jerry Goldsmith’s The Omen), and sound-design-first aesthetics became common for jump-scare punctuation and atmosphere.
Horror scores blended orchestral writing with industrial textures, granular sampling, and design-forward techniques. Composers like Christopher Young, Marco Beltrami, and later Joseph Bishara developed dense, low-end-heavy palettes that merged concert-hall writing with studio-based sound sculpture.
The genre diversified across art-horror and prestige cinema (e.g., Michael Abels in Get Out/Us; Bobby Krlic for Midsommar; Mark Korven’s microtonal and prepared-instrument palettes in The Witch/The Lighthouse), television, and games (Akira Yamaoka’s Silent Hill). Horror’s musical vocabulary now comfortably spans orchestral modernism, dark ambient, and retro-analog synth, united by its core purpose: to evoke fear and existential unease.
