How to Choose Music for an Indie Game Trailer

A game trailer has to communicate its world, pace and tone in a short time. Music can help shape that impression, but a trailer soundtrack and in-game music are different uses. Before choosing a track, decide where the audio will appear and check that the licence covers those uses.

Trailer use and in-game use are different

A promotional trailer might be published on a video platform, a store page or social media. In-game music may be part of the interactive game itself. Don’t assume permission for one automatically covers the other.

Write down the planned uses: trailer, gameplay demo, launch announcement, paid ad, livestream or the game’s soundtrack. Check the current licence terms against that list before production.

Match the music to the game’s identity

Start with the trailer edit. Is it introducing a calm exploration game, a fast action game or a puzzle adventure? Look for a track that supports the world and gives the edit room to build.

If the trailer has dialogue or gameplay audio, avoid music that masks important details. Use natural breaks in the track to make room for a reveal, a line of dialogue or a title card.

Build the sound around key moments

Use music to support the trailer’s arc: opening, build, reveal and finish. Sound effects can make interface actions, movement or transitions easier to read, but each should have a purpose. Too many impacts and whooshes can make the trailer feel cluttered.

Preview the mix at the same size and volume as a typical viewer will hear it. A strong mix on editing headphones may feel overwhelming on a phone.

Plan for the campaign

A launch campaign may have several edits and destinations. A trailer might be cut into a shorter teaser, a vertical clip or an ad. Check whether those versions are covered and save the licence details alongside the project.

If you need music inside the game itself, confirm that the licence explicitly allows that use. Ask the rights holder or platform support if the terms aren’t clear.

Make a rights checklist

Before publishing, list each asset, its source and the planned use. Keep the licence document with the final deliverables so the team can check it again if the campaign changes.
