Scary music for videos, built around your scares

Upload your horror video and Sonilo makes music that follows it: a slow drone while the camera creeps forward, rising tension through the long hold, and space left for the scare. Start from a preset or describe exactly what should frighten people.

01

Fear lives in the quiet

Horror is the one genre where the most important musical decision is when to stop. A jump scare only works if the viewer has been pulled into a quiet moment first, close enough to the screen that a sudden sound or image catches them off guard. Music that plays straight through the scare cushions it. Music that cuts out a second or two before leaves the viewer alone with the silence, and that is when they start to brace.

Plan your scares first, then decide where the music sits around them. The music is there to build pressure and then to get out of the way.

02

Building dread

Dread comes from music that does not resolve. Long low drones, slowly bending pitches, notes that clash without settling, and a pulse that sits just under the threshold of hearing all keep the viewer uneasy without telling them why. Melody is usually the enemy here. Once something sounds like a tune, the audience relaxes into it.

Let the build be slow. A tension bed that rises over 20 or 30 seconds, adding a layer at a time, is far more unsettling than one that ramps up in five. Cut the footage to match: long holds, slow pushes in, a figure barely visible in the background of a wide shot. When you upload, Sonilo reads the pacing of those long takes and keeps the music sparse where your edit is slow.

Check the build on a phone. Most viewers watch horror shorts on phone speakers, which barely reproduce deep bass, so a drone that rumbles on headphones can vanish entirely. Make sure some of the tension lives in the middle range too: high strings, a breathy texture, a quiet ticking that survives a small speaker.

03

Timing the jump scare

The classic shape is drone, silence, hit. The drone builds tension, the music drops out completely, the viewer waits, and then the scare lands with a loud sting or a sharp sound. The gap is the important part. Somewhere between one and three seconds of near silence is usually right, long enough to feel wrong but not so long that the tension leaks away.

Vary the pattern. If every silence leads to a scare, viewers learn the rule by the second one. Use a silence that leads to nothing, then scare them during what feels like a calm moment. After a scare, give the audience a breath with something quiet before the dread starts again.

04

Leave room for the sound design

Footsteps on floorboards, a door hinge, breathing close to the microphone, a phone buzzing in an empty room: horror depends on small sounds that the audience strains to hear. A busy music bed hides them. Keep the music low in volume and thin in texture during these moments, and keep its low end controlled so it does not mask the rumbles and thuds you are using for effect.

If your scare comes from a natural sound, such as a knock or a scream, let that sound be the sting. Adding a musical hit on top often makes the moment feel staged.

If you narrate over location footage, such as an abandoned building or a night walk through woods, keep the real ambience under both the voice and the music. Wind, dripping water and distant traffic make the place feel real, and the music can sit lower than you expect when the ambience is doing half the work.

05

Different kinds of horror video

Horror on YouTube and social platforms comes in a few distinct shapes, and the music approach changes with each.

  • Horror shorts for TikTok, Reels and Shorts: 30 to 90 seconds, a hook in the first two seconds, one build and one scare near the end.
  • Scary story and creepypasta narration: 10 to 40 minutes of voice over slow images, a steady dark bed that never competes with the narrator.
  • Found footage and haunted location videos: little or no music, or only sounds that could plausibly exist in the space.
  • Short horror films: music used sparingly, mostly for openings, the final act and the credits.

06

Music under a narrated scary story

Narration channels live or die on the voice. Record close to the microphone, keep the music well below it, and choose low, slow textures that stay out of the speech range. A heartbeat pulse or a quiet drone can run for minutes without tiring the listener. Change the bed when the story moves to a new night or a new location, and pull it out for the line that delivers the twist.

Leave the speech setting on when you upload so your narration stays in the mix while the music around it is replaced. Keep any musical stings for the visual beats between paragraphs, never on top of a spoken word.

07

Choosing sounds for the kind of fear

Different horror needs different textures. Pick the palette from what the audience is afraid of, not from what generally sounds scary.

  • Ghosts and haunted places: sparse piano, bowed metal, distant voices, long reverb tails.
  • Psychological horror: close, dry sounds, a ticking pulse, slightly detuned strings.
  • Creatures and monsters: deep low brass, heavy drums held back until the reveal.
  • Folk horror: old instruments played wrong, a simple tune that slowly decays.
  • Comedy horror: spooky clichés played straight, with timing that leaves room for the joke.

08

Endings that stay with people

A horror ending rarely resolves. The final scare, a last shot that suggests the threat is still there, a cut to black on an unfinished note: all of these leave the viewer uneasy after the video stops. Avoid ending on a comforting final chord unless the story has truly finished. A single sustained tone that cuts off on the black frame is usually stronger.

For credits or an end card, a slow, dark piece on piano or strings lets viewers come down without breaking the mood. Keep it short. Long credits music after a 60 second horror short just gives people a reason to scroll away.

FAQ

Questions before you start

Should music play during a jump scare?

Usually the music drops out one to three seconds before the scare, so the viewer sits in near silence, and the scare lands with a sharp sound or sting. Music running straight through tends to soften the moment.

What makes background music sound scary?

Low drones, slowly bending pitch, clashing notes that never resolve, sparse piano and bowed textures with long gaps between sounds. Clear melodies and steady beats usually make horror feel safer.

Do found footage videos need music?

Often not. Found footage feels real because there is no music, only sounds that could exist in the space. If you add anything, keep it to a very low drone that the viewer feels more than hears.

Can I use this for a narrated scary story channel?

Yes. The Scary story preset is a steady, dark bed built to sit under a narrator for long stretches. Keep the speech setting on and set the music low before export.

Can I use this music in videos I publish, monetize or make for clients?

It depends on your plan. Music you generate on Free or Creator is for personal use only. Pro, Premium, Enterprise and eligible API users get commercial use rights, which cover monetized channels, client work and ads under the current terms. Tracks from the Sonilo music library are free for personal use, and commercial use of them also needs Pro or above.
