Prompting & lyrics
The prompt is the instrument — style language, structure tags, vocal direction, and iterating toward a keeper.
Prompting basics
Style description
Genre, era, instrumentation, mood, and vocal character in plain language — "moody 90s trip-hop, female alto vocal, sparse Rhodes, brushed drums" reads more reliably than a single genre word.
Structure tags
Section markers like [Verse], [Chorus], [Bridge], [Outro] in the lyric field help SUNO understand arrangement intent rather than treating the whole lyric block as one continuous idea.
Negative/avoid language
Same principle as Moises prompting — stating what to avoid ("avoid busy drum fills," "no key change in the final chorus") narrows the result as much as stating what you want.
Iteration over one-shot
Treat the first render as a draft. Regenerating sections, adjusting style tags, and re-rolling specific passages tends to get you closer than trying to perfect one prompt up front.
Vocal direction
Steer the performance, not just the timbre — register, delivery, and how the voice is arranged. "Intimate, breathy male tenor, light doubled harmonies on the hook, a few ad-libs in the outro" shapes how the vocal is sung and stacked, not just what it sounds like.
Production & energy tags
Parenthetical descriptors and dynamic cues shape the mix and the arc rather than the notes — (reverb-drenched), (lo-fi tape), "drop to just vocal and pad in the bridge," "build to a big final chorus."
Working the lyric field
- Write your own lyrics when the words matter. SUNO will happily invent lyrics from a theme, and for throwaway sketches that's fine — but a lyric you wrote lands with intent, and it's the strongest single lever you have over what comes back.
- Structure tags are arrangement instructions, not decoration. A tagged lyric tells SUNO where the song turns; an untagged block leaves the form to chance.
- Performance cues can live in the lyric itself. Parentheticals placed where you want them — an answering "(ooh)" after a hook line, an ad-lib in the outro — tend to land closer to intent than describing the same idea abstractly in the style field.
Iterating toward a keeper
- Change one variable at a time. If a render is close, adjust only the style line, or only one section's lyric — change three things at once and you can't tell which one moved the result.
- Extend from the good part. Continue or extend an existing generation to build out a longer arrangement from a section you already like, rather than re-rolling the whole song and hoping the good section survives.
- Reuse what works. A saved style or persona carried across generations keeps a consistent sonic identity over a set of songs — the closest thing prompting has to a band.
- Know when to stop. Past a certain point, another re-roll costs more credits than fixing the one weak part downstream — that's exactly the repair job Moises exists for.
Common use cases
- Full-song ideation — generate a complete arrangement and vocal as a starting sketch, then treat everything downstream (Moises, Logic) as the repair/finishing pass.
- Extending an idea — continue or extend an existing SUNO generation to build out a longer arrangement from a section you already like.
- Instrumental-only renders — generate without vocals when you want a backing track to write a live vocal over, or to feed into Moises for instrument-level repair.
- Style/persona consistency — reusing a saved style or persona across multiple generations to keep a consistent sonic identity across a set of songs.
