Most Suno prompts read like wishes: “happy upbeat pop song.” Suno hears that and gives you the statistical average happy upbeat pop song. The fix is not better adjectives. It is treating the Style field as a recipe card with named ingredients, and putting the right ingredient in the right field. This guide is current for Suno v5.5 as of June 2026.
TL;DR
- Write the Style field as comma-separated ingredients, not a sentence: genre, sub-genre, era reference, BPM, mood, instruments by role, production style, vocal tone.
- Front-load the tags that matter. The Style field is short (roughly 200 characters in practice) and Suno silently truncates the overflow, so put genre and the two most important instruments first.
- Structure tags like
[Verse]and[Chorus]belong in the Lyrics field, not the Style field. - Change ONE ingredient between generations so you can learn what each word does.
- v5, v5.5, and commercial rights require a paid plan ($8/mo Pro as of June 2026); the free tier is v4.5-all only.
Custom Mode is where prompts live
In Simple Mode you type one description and Suno guesses everything. For reproducible results, switch to Custom Mode, which splits your input into separate fields:
- Style of Music — genre, mood, tempo feel, instrumentation, vocal lane, atmosphere. This is the “recipe card.”
- Lyrics — the actual words plus structure metatags. Section markers and performance cues live here, not in the Style field.
Putting [Chorus] in the Style field does nothing useful. Putting “warm Rhodes piano” in the Lyrics field confuses the vocal alignment. Keep ingredients in their own bowl.
The seven-ingredient Style recipe
Six to seven specific ingredients beat one vague sentence every time:
| Ingredient | Weak | Strong |
|---|---|---|
| Genre + sub-genre | ”rock" | "early-2000s indie rock” |
| Era / reference | (omitted) | “like The Strokes” |
| Tempo | ”medium tempo" | "118 BPM” |
| Mood | ”good vibes" | "wistful, restless, hopeful” |
| Instruments by role | ”guitars and drums" | "lead: clean electric; rhythm: muted acoustic; bass: warm tube; drums: tight punchy kit” |
| Production style | (omitted) | “lo-fi cassette warmth” |
| Vocal tone | ”nice vocals" | "smoky female alto, sparse vibrato, conversational delivery” |
A few notes on why each one moves the output:
- Era / reference is the single highest-leverage tag. Without it, Suno over-defaults to a generic 2020s pop production. “Early-2000s indie rock, like The Strokes” gives the model a concrete target era to aim at.
- BPM is guidance, not a metronome lock. “118 BPM” reliably lands faster than “112,” but treat the number as a strong hint rather than an exact clock. It still beats “medium tempo” by a wide margin.
- List instruments by role. Suno respects “lead / rhythm / bass / drums” structure far better than a flat list. Naming the role tells it where each instrument sits in the mix.
- Production style sets the entire feel. “Lo-fi cassette warmth,” “polished modern pop mix,” and “live concert reverb” produce dramatically different masters from the same notes.
- Vocal tone is separate from accompaniment. Suno treats voice and band independently, so “breathy male tenor, intimate” is its own ingredient. If you are using a cloned or saved Voice, drop the vocal descriptor entirely and spend that character budget on production detail instead — describing a voice you have already pinned is redundant.
Front-loading: why order matters
The Style field is short. On v4.5 and newer the practical ceiling is around 200 characters for the part Suno weights most heavily, and anything past the limit is silently truncated with no warning. Two consequences:
- Put the dominant genre and your two most important instruments first. If the tail gets cut, you want the cut to land on the least important descriptors.
- Combine at most two genre tags. “Synthwave, dream pop” can fuse into something interesting; “synthwave, dream pop, metal, jazz, country” produces mud. Place the dominant genre first so Suno knows which one wins.
Negative direction
There is no separate exclude field in the standard flow, but Suno v5.5 honors short negative cues placed directly in the Style field. Prefix the unwanted element with “no”:
no drumsfor an ambient pad trackno autotune, no synthsto keep an acoustic recording dry
Negatives are less reliable than positive direction, so reach for them only after the positive ingredients are dialed in. For a fully instrumental track, use the Instrumental toggle rather than relying on “no vocals.”
A real workflow: coffee-shop background track
- Write the structured Style prompt:
lo-fi jazz, 80 BPM, warm and unhurried, lead: Rhodes piano; bass: upright; drums: brushed kit; production: cassette warmth; smoky female alto humming - Generate two takes. Suno always returns a pair — compare them before touching the prompt.
- You like 50% of take one. The mood is right but the humming is too prominent.
- Change exactly one word:
humming→wordless. Leave everything else untouched. - Regenerate. Now you know precisely what that one word did, and you keep a version that works.
This one-variable-at-a-time loop is the whole skill. Changing five ingredients at once means you learn nothing from the result.
Common mistakes
- Stacking opposing styles. “Metal but also jazz” gives muddy, confused results. Pick one dominant genre.
- Changing everything between generations. You can’t learn what works if every variable moved.
- Skipping the era / reference. This is the number-one reason songs sound generic.
- Writing the prompt as a paragraph. Comma-separated ingredients parse far more reliably than prose.
- Putting structure tags in the Style field.
[Verse]and[Chorus]belong in the Lyrics field. - Overstuffing. Past your character budget, Suno just drops the tail. More words ≠ more control.
Save your best prompts as templates
For consistency across a multi-song project, save a “house style” prefix (genre + production + vocal tone) and reuse it, swapping only the per-song details. This is the closest Suno gets to a reusable instrument patch.
Copy-ready Style prompt
Paste into the Style of Music field and replace each bracketed placeholder. Keep the whole thing tight so the important tags survive truncation:
[sub-genre], [era reference], [BPM] BPM, [2-3 mood adjectives],
lead: [x], rhythm: [y], bass: [z], drums: [style],
production: [style], vocals: [voice type, delivery]Structure tags for the Lyrics field (not the Style field):
[Intro]
[Verse]
[Pre-Chorus]
[Chorus]
[Bridge]
[Outro]Which plan do you need?
Prompt quality is independent of plan, but model access is not. The free tier cannot use v5 or v5.5 and grants no commercial rights. Pricing as of June 2026:
| Plan | Price (monthly / annual) | Credits | Models | Commercial use |
|---|---|---|---|---|
| Basic (Free) | $0 | ~50/day (~10 songs) | v4.5-all only | No |
| Pro | $8 / $6.40 | 2,500/mo (~500 songs) | up to v5.5 | Yes |
| Premier | $24 / $19.20 | 10,000/mo (~2,000 songs) | up to v5.5 + Suno Studio | Yes |
If you are testing prompt structure, the free tier is fine. The moment you need v5.5 quality or want to publish anywhere, you need at least Pro. See the official Suno pricing page for current terms.
FAQ
How long should the Style prompt be? Short. The field practically weights the first ~200 characters and silently truncates the rest, so aim for tight, comma-separated ingredients and front-load genre plus key instruments. There is no benefit to padding it out.
Should I write lyrics inside the Style field? No. Use the dedicated Lyrics field for words and structure tags. The Style field is style only — mixing them degrades both.
Why do my songs default to 2020s pop? You almost certainly skipped the era / reference tag. Add a concrete one (“late-90s trip-hop,” “1970s funk, like Parliament”) and the production shifts immediately.
Can I lock an exact BPM? Not exactly. A number like “118 BPM” is strong guidance, not a metronome lock, but it lands much closer than “medium tempo.” Match it in the Lyrics phrasing for tighter results.
Do I still describe the voice if I’m using a cloned Voice? No. Once you have pinned a saved or cloned Voice, a vocal descriptor in the Style field is redundant and wastes your character budget. Spend those characters on production detail instead.
Is the free plan enough? For learning prompt structure, yes. For v5.5 quality or any commercial release, no — the free tier is locked to v4.5-all with no commercial rights, so you need Pro ($8/mo as of June 2026) or higher.
