Sell the Tension: Inside the Ad Industry's Quiet Obsession With Music That Makes You Flinch

The first time you hear it, you might not even register it consciously. A car commercial. A tech brand launch video. A trailer for a streaming series. Underneath the visuals, there's something in the music that doesn't quite resolve — an interval that hangs in the air, a harmonic choice that creates a faint but persistent sense of unease. You feel it before you understand it. And that, according to the people who put it there, is exactly the point.

Dissonant music — the kind that builds on unresolved tension rather than satisfying resolution — has been creeping into mainstream advertising for years. But recently, that creep has become something closer to a sprint. Music supervisors, brand strategists, and creative directors across the US are actively seeking out challenging, Locrian-influenced compositions for campaigns that want to do something more than make you feel good. They want to make you feel something you can't shake.

The Problem With Pretty

For most of advertising's history, music was a comfort delivery system. The logic was simple: pair your product with something that makes people feel warm and safe, and they'll associate that warmth with your brand. It worked. For a while.

But somewhere in the last decade, audiences started tuning out the warmth. Ad fatigue set in. The pleasant piano melody, the acoustic guitar strum, the inspirational string swell — these sounds became invisible precisely because they were everywhere. They signaled "advertisement" before a single image appeared, and that signal told viewers' brains to disengage.

"We kept doing research that showed audiences checking out within the first three seconds," says one creative director at a mid-sized New York agency who asked not to be named because their firm hasn't publicly discussed the shift in their music strategy. "The safe, pleasant stuff wasn't safe anymore. It was just boring. We needed something that would make people stay in the room."

Dissonance, it turns out, is very good at making people stay in the room.

The Neuroscience of the Sale

There's a physiological reason why uncomfortable music holds attention differently than comfortable music. The brain, when it encounters unresolved harmonic tension, enters a mild state of alert. It's waiting for resolution that doesn't come — or that comes later than expected, in a form it didn't anticipate. That state of alert is the opposite of the passive comfort response that pleasant music triggers.

For advertisers, that alert state is gold. An engaged brain is a brain that's processing information, forming associations, and — critically — remembering. The discomfort becomes the hook. The product placed against that discomfort gets encoded more deeply than it would against a backdrop of sonic wallpaper.

Film trailer editors figured this out years ago. The rise of the "braaam" — that massive, processed low-frequency hit that became ubiquitous in action and thriller trailers — was an early mainstream application of the same principle. Dissonance in the trailer creates urgency. Urgency sells tickets. The logic translated almost directly to advertising.

What the Music Supervisors Are Actually Licensing

The music that's getting picked up for these campaigns isn't always explicitly experimental. Sometimes it's a conventional-sounding piece with one or two harmonic choices that introduce subtle tension. Sometimes it's something more overtly challenging. The common thread is intentionality: music that uses dissonance as a compositional tool rather than an accident.

Jenna Park, a music supervisor based in Los Angeles who works across advertising and film, describes the shift in what her clients are requesting. "Three years ago, I'd get briefs that said 'emotional but not too dark.' Now I get briefs that say 'we want something that feels like it's about to break.' That's a fundamentally different ask, and it opens the door to a whole world of music that used to be considered too risky for this context."

The genres feeding this demand are varied. Experimental electronic music, post-metal, contemporary classical, and drone-influenced ambient work are all showing up in sync licensing pipelines that would have rejected them outright a few years back. Artists who spent years releasing records to small but devoted audiences are suddenly getting calls from brands they'd never imagined would be interested.

Case Studies in Discomfort

Some of the most memorable recent campaigns have leaned directly into the tension that dissonant music creates. A major automotive brand used a piece built on sustained, unresolved intervals for a launch campaign emphasizing the idea that their vehicles were built for people who "don't settle." The music, which never fully resolved until the final frame, was designed to make viewers feel the same restless energy the campaign was selling.

A streaming platform's campaign for a prestige thriller series used music that mixed conventional orchestral writing with Locrian-influenced passages — sections where the harmonic center felt deliberately unstable. Viewers reported feeling anxious in a way that made them want to watch the show to find relief. The campaign outperformed projections by a significant margin.

A tech company's product launch video used a composition that began with conventional harmony and gradually, almost imperceptibly, introduced dissonant elements as the video built toward its reveal. By the time the product appeared on screen, viewers were primed for something significant — and the dissonance, finally resolving at that moment, created a release that felt like relief. It was engineered suspense, and it worked.

The Artist's Dilemma

Not everyone in the experimental music world is celebrating the attention. There's a real tension — no pun intended — between the financial opportunity that sync licensing represents for independent artists and the discomfort of having music made as a form of artistic expression repurposed to sell cars or streaming subscriptions.

Some artists have drawn clear lines. Others have made peace with the commercial use of their work, particularly when the alternative is releasing records to small audiences while working day jobs that leave little time for music. The money from a single sync deal can fund years of independent recording.

"I made a decision early on that I wasn't going to be precious about it," says one experimental composer who has licensed work to two major advertising campaigns in the past year. "The music exists. It's doing something in those contexts that it couldn't do just sitting on Bandcamp. And the check let me take six months off from my other job and finish the record I actually care about."

The Long Game

What's most interesting about this trend isn't the individual campaigns. It's what it signals about where mainstream culture's relationship with discomfort is heading. For decades, challenging sounds were kept at arm's length by industries that assumed audiences wanted only comfort. The evidence is now pointing in a different direction.

Audiences — particularly younger ones — are not just tolerating dissonance in commercial contexts. They're responding to it. The brands that figured this out first are seeing results. The ones still chasing the warm piano melody are watching their ads get skipped.

The tension, it turns out, was always there. Someone just had to be brave enough to sell it.
