Built for v6Updated Jun 2026~8 min read

This is the only Suno prompt guide built around how SPM's prompt generator works — and what actually makes Suno produce a track that sounds like you imagined it. Not theory. Not templates. Real prompts, genre by genre, with the logic behind every element.

Whether you're writing your first Suno style field or you've burned 200 credits chasing a specific sound, this guide tells you exactly what Suno needs to deliver.

01 — Fundamentals

What Is a Suno Prompt?

A Suno prompt is the text you put into Custom Mode to tell Suno what kind of music to make. It has two parts:

Style Field

A 1000-character text input describing the musical character: genre, sub-genre, BPM, key, instrumentation, groove, energy, mood, and label/artist references. This is the most important input — it's what SPM generates.

Lyrics Field

The actual song text, optionally with structure tags like [Verse], [Chorus], [Bridge]. SPM generates this too — or you can write it yourself and use SPM just for the style field.

The most common mistake: typing a genre name and nothing else. "Deep house" gives Suno the same brief as a million other prompts. A 900-character style field with BPM, key, groove character, instrumentation, label reference, and emotional arc gives Suno a specific creative target. The difference in output quality is dramatic.

02 — The Style Field

Style Field Anatomy: What to Include

A great Suno style field has 8 core elements. Miss any of these and Suno fills the gap with its own defaults — which are usually wrong:

Sub-genre stack
Not just 'techno' — 'peak-time industrial techno with hypnotic elements'. Stack 2–3 sub-descriptors for precision.
BPM
Exact BPM gives Suno a tempo anchor. A range (e.g. '124–128 BPM') allows flexibility. Don't omit this.
Key signature
'F minor', 'B-flat major' — this affects the harmonic character of the output significantly.
Defining element
What makes this track unique? A specific instrument, a sound design choice, a signature technique. 'Hypnotic chopped vocal sample as the defining hook element'.
Groove character
How does the rhythm feel? 'Syncopated tribal percussion', 'swinging jazz-influenced swing', 'four-on-the-floor with organic swing'. This is what makes it feel human.
Instrumentation
List the key instruments in priority order. Rhodes, congas, synth pads, sub-bass. The first items Suno will weight most heavily.
Energy & emotional arc
How does the track feel and develop? 'Gradual hypnotic build with restrained dynamics', 'tension and release with euphoric resolution'.
Label reference
'Innervisions aesthetic', 'Drumcode engineering standard', 'Warp Records experimental approach'. These are massive creative shorthand for Suno.

Character limit tip: Suno's style field accepts 1000 characters. SPM calibrates every output to 850–990 chars, exclusions included, and never over 1000. Shorter than 600 chars leaves creative decisions to chance. Aim for maximum useful detail without repetition.

03 — Suno v6

How to Prompt Suno v6 (v6, v6-wild and v6-mini)

Suno v6 replaced every earlier model. According to Suno, it understands more of the language musicians use — vocals, instrumentation, structure, mood and feel. Here's what that means for your prompts:

Pick the right model

v6 (Pro/Premier) for precision, v6-wild (Pro/Premier) for exploration, v6-mini for everyone including the free plan. The same prompt works on all three.

Set Variety to 0

Suno says Variety adjusts and updates your style prompt. At 0 your style tags stay exactly as written — essential when the prompt was decoded from a real record.

Direct every section

Give each lyric section tag a short performance command: [Chorus: 16 bars | full belt, stacked harmonies, full band]. This is where verse-to-chorus contrast is won.

Max Mode for long tracks

Suno recommends Max Mode for songs over two minutes and for keeping vocals and style consistent. It costs more credits, so save it for the take you mean to keep.

Exclusions on every plan: SPM closes the style prompt with its exclusions ("no autotune, no glossy overproduction") so they work on free v6-mini too — and the whole field stays strictly under 1000 characters. Full breakdown: the Suno v6 prompt generator.

04 — What a real prompt looks like

A Real Suno Style Field Prompt

Here's what a fully engineered SPM-style style field looks like — all 8 elements woven into a single 900-character prompt. This is the difference between a vague brief and a creative target Suno can actually hit.

Deep Afro House — Black Coffee / Innervisions style
deep afro house, 121 BPM, F minor, hypnotic chopped vocal sample as defining hook, rolling syncopated tribal percussion with live conga and shaker layers, deep round sub-bass with subtle sidechain, warm Rhodes chord stabs drenched in analog tape saturation, distant melancholic synth pads across eight-bar phrases, sparse male vocal fragments with plate reverb, organic shaker-driven groove, late-night open-air festival energy, South African deep house lineage, Innervisions and Stil vor Talent aesthetic, immersive spatial mixdown with wide stereo percussion, soulful melancholic undertone

SPM generates this for you — decoded from any reference track you give it. Enter an artist or song name, pick your creative mode, and get a prompt like this tailored to that exact sound in 20 seconds. Try it free →

05 — Input

Choosing a Reference Track

Your reference is the musical starting point. Here's what makes a great one:

Well-known tracks
Tracks with global streaming presence return the richest DNA analysis — more sub-genre nuance, clearer energy data, fuller structural breakdowns.
Artist-only input
Type just an artist name (e.g. 'Fred Again', 'Bicep') and SPM synthesises a composite style from their catalogue — great for capturing a sound rather than a specific song.
Obscure tracks
Very underground releases may return thinner analysis. Try a better-known track in the same vein if the result feels shallow.
Avoid descriptions
Don't type genre descriptions. Use a real artist or track name — SPM is tuned for that input, not freeform text.
Adjacent reference trick
If your target sound is very niche, use a bigger-name artist in the same sonic territory. The resulting DNA will be richer and you can dial in specificity with the Creative Mode.
06 — Controls

Lyric Density Decoded

The density slider controls vocal content and how the style field instructs Suno's vocal treatment:

Instrumental (0)

No lyrics. Style field steers toward instrumental arrangement. Best for background music, DJ tools, cinematic pieces.

Club Tool (20)

Minimal vocal — short chops, one-line hooks, crowd-ready call-outs. Mirrors peak-time dance music vocal treatment.

Light Vocal (40)

Sparse hook lines, breathing room between phrases. Production is the main event.

Full Vocal (60–75)

Complete verse-chorus-bridge structure. The default — works for most genres. Most Suno-ready lyric layout.

Dense Vocal (90–100)

Wall-to-wall lyrics with layered inner rhymes. Best for hip-hop, dense pop, any genre where lyrics are the core product.

07 — Controls

Creative Modes

Creative mode controls how far SPM strays from the reference's DNA when building your blueprint:

FAITHFUL

Stays as close as possible to the reference. All key musical parameters (BPM, key, sub-genre, groove feel) are preserved. Best when you want to sound exactly like the reference era/style.

INSPIRED

Borrows the emotional feel and energy signature but allows genre drift, BPM variation, and structural creativity. The sweet spot for original tracks that carry the spirit without sounding like a copy.

REIMAGINED

Uses the reference as a distant moodboard. Maximum creative latitude — tempo, key, and genre can shift significantly. Best for experimental or hybrid tracks.

08 — Controls

Themes & Languages

Lyric Theme (optional): A freeform field that steers imagery and subject matter. Examples: "late night driving through coastal fog", "losing someone to distance", "euphoria on the dancefloor at 4am". Leave blank and SPM infers a theme from the reference's emotional arc.

Language: SPM can generate lyrics in any major language. The style field always stays in English (Suno's native input), but lyrics can be in any language — including native orthography, not transliterations. For multilingual verses, request it in the theme field.

Theme examples that work well: Keep it imagistic and specific. "Heartbreak in a neon city" works better than "sad". "A road trip through the desert at golden hour" works better than "happy and free". Give Suno a scene, not an emotion label.

09 — Workflow

Using Your Blueprint in Suno

1

In your SPM result, click "Copy Style" to copy the full Style Field to clipboard.

2

Open Suno and create a new song. Click "Custom Mode".

3

Paste the Style Field into the "Style of Music" box. Do not edit or shorten it — it's calibrated to the character limit.

4

Back in SPM, click "Copy Lyrics" and paste into Suno's lyrics box.

5

Hit generate. Your first take should land dramatically closer to the sound in your head.

6

If close but not perfect: go back to SPM, tweak density or creative mode, and rebuild. One tweak per iteration — don't change everything at once.

Pro Tips for Better Suno Prompts

Use the Analyse step for free research

The Analyse step doesn't cost tokens. Use it to explore the DNA of multiple references before you commit to building a blueprint. Learn what makes your target sound tick.

Stack label references

Multiple label references give Suno a quality bracket: "Innervisions and Crosstown Rebels aesthetic, Stil vor Talent engineering standard". This is shorthand for production quality, not genre.

Iterate density first

If the vocal output feels wrong, adjust density by 15–20 points and rebuild before changing anything else. This is the single most impactful variable for vocal character.

REIMAGINED for hybrid genres

If your goal is to blend two distant genres (e.g. Afro house + cinematic ambient), use a reference from the more dominant genre and REIMAGINED mode. Add the secondary influence in your theme.

Archive stars as genre presets

When a blueprint nails a specific genre, star it in your archive. Use it as a starting reference for future tracks in that genre — compare the decoded DNA against new references.

Explicit bar counts in themes

For tracks with unusual structure, add a structural note in your theme: "extended 32-bar intro before first vocal, 8-bar breakdown before final chorus". SPM will work this into the lyrics.

11 — Avoid These

Common Suno Prompt Mistakes (and How to Fix Them)

✗ Too short: "deep house, emotional, 120 BPM"
Fix: Add sub-genre descriptors, key signature, defining element, groove character, instrumentation, label reference, and emotional arc. Aim for 800+ characters.
✗ Contradictory instructions: "aggressive but calm, loud but soft"
Fix: Pick one emotional register per section. If you want contrast, describe it structurally: "tense building verses contrasting with euphoric released chorus".
✗ Too many genres at once: "hip-hop jazz techno ambient soul"
Fix: Lead with the primary genre and use maximum one or two secondary influences. "Jazz-influenced melodic techno with neo-soul vocal treatment" is coherent. Five genres are not.
✗ Cutting the generated style field short
Fix: Suno's style field is calibrated for 1000 chars. SPM outputs 800–950 chars of structured information. Trimming it removes creative direction that Suno was going to use.
✗ Describing lyrics instead of music in the style field
Fix: The style field is for musical character, not lyrical content. "A song about heartbreak" goes in the theme field or lyrics — not the style field.
