How to Brief a Music Supervisor for Your Ad Campaign

By Elad Marish, Founder \& ECD, Swell Music + Sound · \ May 8

A great brief is the fastest path to great music. A vague brief — the kind that says "upbeat and modern" and not much else — is the surest path to three weeks of back-and-forth and a mediocre track.

What a music supervisor does (and what they don't)

A music supervisor's job is to find, pitch, and secure the right music for your project. On the advertising side, that means understanding the spot's emotional arc, sourcing tracks that fit the budget and the vibe, and negotiating rights and licensing. They are not mind readers. The brief is the raw material.

What a good music brief includes

The spot itself. Send the cut. Even a rough cut. Music supervisors need to hear the edit rhythm, the dialogue timing, the emotional peaks and valleys. A script or storyboard is not sufficient. The cut is the assignment.
Reference tracks — with specific notes. Not "something like Billie Eilish." More specific: "Billie Eilish's 'Happier Than Ever' — specifically the sparse, intimate feel of the first half before the drop." Reference tracks are invaluable, but the note needs to explain what about the reference you want. Give three or four references. Explain what each is doing that works.
The emotional job of the music. What is the music supposed to make the viewer feel? "Happy" isn't enough. "Nostalgic warmth with an undercurrent of forward momentum" is useful. Be specific about the emotional arc.
What it should NOT be. "Don't give us anything that sounds like a yoga retreat" or "no acoustic guitar, the brand already over-indexed on that" saves enormous time. Constraints that eliminate categories help a supervisor narrow fast.
Sync vs. custom. Tell your supervisor upfront whether you're looking to license existing music, commission an original track, or you're open to both.
Budget and media rights. Ballpark the budget before the supervisor searches. "We have $20K for music" is not the same project as "we have $200K for music." Knowing the budget means the supervisor searches in the right neighborhood.
Timeline. When is the spot locking? When do you need to present options? When is broadcast? Work backward from delivery and tell the supervisor the actual milestones.
Brand context. Are there previous spots the music should feel continuous with? Are there sonic identity guidelines? Is there a competing campaign running simultaneously that you want to sound different from?

A real example: bad brief vs. good brief

Bad brief: "We need something energetic and inspiring for a sports brand."

Good brief: "We're cutting a 60-second film for a running shoe launch. It follows a solo female runner from pre-dawn preparation through a finish line moment at sunrise. The tone is gritty and intimate — this is not a triumphalist anthem, it's a quiet personal victory. Think less 'Eye of the Tiger,' more Hozier's 'Work Song' — raw, a little haunting, building slowly. We have $35K for the sync, national broadcast rights, 12 months. Locking picture in three weeks."

The second brief is a brief. The first one is a vibe.

One more rule

Bring your music supervisor in as early as possible. The best music discovery often happens when there's still time to let the edit breathe around a track — not when the spot is locked and you're scrambling in the last 48 hours.
