Decode Any Music Supervisor Brief
A brief isn't a wishlist — it's a specification. Paste one into the Brief Checker and TuneLens turns it into concrete targets, then tells you which of your tracks actually fits.

When a music supervisor needs music for a scene, spot, or trailer, they write a brief: a short spec describing exactly what the picture needs. Read literally, a brief tells you almost everything — the trouble is that most makers read it as encouragement ("uplifting indie pop") rather than as a set of pass/fail constraints. Brief Checker exists to remove that ambiguity.
A typical brief encodes seven things:
Mood & emotion
The feeling the cue must carry — "hopeful but restrained," "tense, building dread." Usually the hardest constraint to fake.
Genre & style
The sonic territory. "Indie folk," "synthwave," "orchestral hybrid." Match the territory, not just the tempo.
Tempo & energy
A BPM range and an energy level that has to fit the pacing of the edit. Too fast or too busy and it fights the picture.
Vocal vs. instrumental
Whether they need a full vocal, an instrumental, or a clean no-lyrics version — often because vocals would collide with dialogue.
Reference artists
The "sounds like" list. The fastest read on the production target — and a trap if you match the artist but not the specific track's mood.
Avoids
The disqualifiers — "no heavy drums," "nothing too poppy." Miss an avoid and a perfect track gets cut anyway.
How Brief Checker works
Paste the brief — and optionally the catalogue name and the supervisor's name for your records. The AI decodes it into the structured targets above: mood keywords, genres, a tempo range, production style, instrumentation, reference artists, and an explicit "avoid" list. No more re-reading a paragraph five times trying to work out what they actually want.
Then match up to three tracks against it — add the track currently loaded in Track Analysis, pick from your saved songs, or upload new MP3s. For each track, Brief Checker returns a verdict: what works, what might not, lyrical fit, and a clear pitch recommendation. Export the whole thing as a PDF. It's the review a sync agent would give your submission before you hit send — except you get it in seconds, every time, for free to start.
Why this protects your relationships
Supervisors remember who wastes their time. Pitching a great track that misses the brief's "avoids" doesn't read as ambitious — it reads as "this person didn't read the brief," and it costs you the next opportunity. Matching honestly, and only pitching tracks that genuinely fit, is how you build the kind of reputation that gets you on a supervisor's shortlist. For more on the etiquette and the misreads that sink pitches, see what supervisors actually look for in a brief and how sync-readiness sets the bar before fit even comes into play.
Frequently asked questions
What is a music supervisor brief?
A brief is a music supervisor's specification for a specific scene, spot, or project. It typically names a mood, a genre or style, a tempo and energy level, vocal vs. instrumental requirements, reference artists or tracks, and a list of things to avoid. It's a spec to match, not a wishlist to interpret loosely.
How do I read a sync brief?
Separate the brief into hard constraints and soft preferences. Mood, tempo, and "avoids" are usually hard — miss them and you're out. References tell you the sonic target; vocal/instrumental requirements tell you which version to send. Then match only tracks that genuinely hit the hard constraints. TuneLens's Brief Checker does this parsing automatically and flags fit per track.
What does Brief Checker do?
Brief Checker decodes a pasted brief into structured targets — mood keywords, genres, tempo range, production style, instrumentation, reference artists, and what to avoid — then matches up to three of your tracks against it. For each track it returns what works, what might not, lyrical fit, and a pitch recommendation, which you can export as a PDF.
Should I send the vocal or instrumental version?
Follow the brief. If it specifies instrumental or "no lyrics," send that — vocals over dialogue are a fast rejection. If it's open, having both versions ready signals you're sync-aware. Brief Checker reads the vocal/instrumental requirement out of the brief and factors lyrical fit into its per-track verdict.
