Scoring Notes

ScoreSchool

If you've only ever thought about scoring films, there's an entire side of this industry you might not know exists — and it works nothing like the model you're used to.

Trailer music.

Every trailer you've ever watched — for a blockbuster, an indie film, a video game — almost never uses the actual film score. It uses a completely separate piece of music, usually licensed from a trailer music library, composed by someone who may have never even seen the finished film.

That's a real, sustainable revenue stream for composers. And the way it pays you is fundamentally different from scoring a film.

Film scoring: the work-for-hire model

When you score a film, you're typically paid a flat creative fee for a specific deliverable. You write to picture, for a specific client, under a specific contract. Your income is largely tied to the number of projects you can take on and the fee you can command for each one.

You may also earn performance royalties down the line if the film gets distributed and your cues get registered with a PRO — but the bulk of your income up front is the fee itself.

Trailer music: the licensing model

Trailer music works completely differently. Instead of being hired for a specific project, you compose standalone cinematic tracks and place them with a trailer music library — companies that license tracks to studios, ad agencies, and trailer houses for use across many different projects.

You're not paid a project fee. You're paid a licensing fee every time a track gets used — and successful trailer tracks can get licensed dozens or even hundreds of times over the years. One well-placed track that lands in a big campaign can pay you more over its lifetime than an entire indie film score.

This means your income isn't purely tied to hours worked. It's tied to how many usable, high-quality tracks you have in the market at any given time. Write once, get paid repeatedly — an entirely different economic model than the one-and-done nature of most scoring work.

Why this matters for composers building a career

Film scoring income is inherently unpredictable — you're only earning when you land a project. Trailer music gives you a way to build a catalog that keeps earning in the background regardless of whether you're actively scoring something else that month.

It's also one of the more accessible entry points into the industry. You don't need a director, a film, or a client relationship to start. You need strong, usable cinematic tracks and a library willing to represent them.

That doesn't mean it's easy — the trailer music space is competitive and libraries are selective about what they accept. But the barrier to entry is different than scoring: it's about the quality and usability of your music, not who you know.

The compositional side is its own skill

Writing trailer music isn't the same as writing a film score, either. Trailers work in tightly structured builds — tension, rise, drop, hit — designed to work independently of any specific footage, often compressed into 60-90 seconds instead of scoring to a scene's natural pacing.

That's a distinct compositional skill from scoring to picture, and it's exactly what I'm covering in a new video series launching this week — breaking down how cinematic trailer music is actually built, structurally and sonically, so you can start writing tracks that libraries and music supervisors actually want.

If building a second income stream alongside your film scoring work sounds interesting, the first video in the series is live now.
