How to brief an AI music model
The model is not guessing your taste. It is guessing your sentence.
Four parts of a good brief
Scene: what the track is for. "A product film" tells the model more than "something modern".
Length: seconds, and whether it should loop.
Instruments: two or three, by name. "Piano and strings" is a brief; "emotional" is not.
Ending: resolve, fade, or loop. This is the part people forget, and the part they notice.
A template
"[Length] [scene] track, [two instruments], [tempo], [ending]."
Example: "60-second product film track, muted piano and soft strings, 90 BPM, ends on a resolved chord."
What to leave out
Do not describe the emotion twice. "Warm and emotional and heartfelt" gives the model one instruction repeated.
Do not name a specific artist. Describe the arrangement instead: what plays, when, and how it ends.
When it misses
Change one thing at a time. If the tempo was wrong, keep everything else and change the number.
If the take fails the quality gate, the credits come back; retrying is not a purchase.
