A good Suno prompt is not a sentence — it is a tight, ordered list of tags that tells the model what kind of song to build. Get the order and the vocabulary right and Suno becomes remarkably consistent. This guide is the map: the formula, a worked example for each part, ready-to-copy genre prompts, and links to the deep-dives when you want more.

Key takeaways

  • Write the style box as comma-separated tags, strongest first: genre, mood, instrumentation, vocal, tempo, fx.
  • State the tempo as a number (e.g. 92 bpm) — Suno reads it.
  • Put song structure and vocal directions in the lyrics box using brackets and parentheses, not the style box.
  • Keep the style prompt short — around 120 characters of specific tags beats a long paragraph.
  • Change one tag at a time when a track misses, so you know what fixed it.

The five-part style formula

Almost every strong Suno style prompt is the same ingredients in the same order. Lead with the elements that define the sound and let the finer details trail behind, because Suno gives the earliest tags the most weight:

THE FORMULA
[genre], [mood], [instrumentation], [vocal style], [tempo], [production fx]

Here is what each slot does and what good tags look like:

What goes in each part of a Suno style prompt
Slot What it controls Example tags
GenreThe overall sound and arrangement. The single most important tag.melodic synth-pop, UK drill, modern country
MoodEmotional colour: key, energy and dynamics.nostalgic, dark and menacing, heartfelt
InstrumentationThe specific sounds you want to hear. Two to four is plenty.analog synth, pedal steel guitar, sliding 808 bass
Vocal styleVoice type and delivery, or instrumental for none.clean female vocals, gritty male rap vocals
TempoSpeed, written as a number.75 bpm, 124 bpm, 140 bpm, half-time feel
Production fxMix and texture finishing touches.gated reverb, vinyl crackle, wide stereo
WORKED EXAMPLE
melodic synth-pop, nostalgic, analog synth, drum machine, clean female vocals, 116 bpm, gated reverb, wide stereo

That prompt is about 110 characters. It names one genre, one mood, two instruments, one voice, a tempo and two production touches — nothing vague, nothing repeated. The full breakdown of why order matters and how to choose each tag lives in how to write a Suno style prompt that actually works.

Tempo: give Suno a number

BPM is one of the highest-leverage tags because Suno follows it closely. Words like "fast" or "slow" are open to interpretation; 124 bpm is not. Match the number to the genre rather than guessing:

Suno BPM starting points by genre
GenreTypical rangeType this
Lo-fi hip-hop70–90 BPM75 bpm
Hip-hop / boom bap85–95 BPM90 bpm
Synthwave100–120 BPM110 bpm
Pop100–120 BPM116 bpm
House / disco120–128 BPM124 bpm
Rock / pop-punk130–160 BPM140 bpm
Trap130–150 BPM, half-time140 bpm, half-time feel
Drum and bass170–175 BPM174 bpm

The half-time trick matters for trap and a lot of modern hip-hop: they are written around 140 BPM but feel half as fast. If a "70 bpm trap" prompt sounds limp, switch to 140 bpm, half-time feel. More genres are in the BPM cheat-sheet by genre.

Structure and vocals: use the lyrics box

Section markers and vocal directions belong in the lyrics field, not the style box. Three conventions do almost all the work:

  • Square brackets mark sections and directions: [Intro], [Verse], [Chorus], [Bridge], [Outro].
  • Parentheses add backing vocals or echoes, sung under the main line.
  • Blank lines and instrumental tags hand the moment to the band, e.g. [Guitar Solo] or [Instrumental Break].
LYRICS BOX EXAMPLE
[Intro]

[Verse]
Streetlights hum a song I used to know
Every window holds a little glow

[Chorus]
Take me back (take me back)
To the summer on the radio

[Bridge]
[Soft female vocals]
Hold the note a little longer

[Outro]
[Fade out]

Short, regular lines with a clear chorus give Suno an easier melody to find. See song structure, brackets and vocal tags for every marker, and writing lyrics for Suno for the words themselves. To get a ready-made sheet in this format, with chords, try the free Suno song builder.

Blending two genres

Stacking three or four genres usually produces mush. The reliable method is one base genre that sets the rhythm and arrangement, plus one accent borrowed from a second genre — an instrument, a texture or a vocal style:

BASE + ACCENT
modern country, heartfelt, acoustic guitar, pedal steel, subtle trap hi-hats, warm male vocal, 96 bpm, polished mix

Country stays in charge; the trap hi-hats are seasoning. The full technique is in how to blend two genres in Suno.

When a track misses: quick fixes

Most disappointing generations trace back to a handful of causes. Check these before re-rolling:

Common Suno problems and the fix
SymptomLikely causeFix
Wrong genreGenre tag buried late, or too many genresMove one genre to the front; drop the rest
Wrong speedNo BPM, or words like "fast"Add a number, e.g. 124 bpm
Sings "verse" or "chorus"Structure written in the style boxMove [Verse] markers into the lyrics box
Generic, bland soundVague tags like "good" or "epic"Name concrete instruments and textures
Ignores half the promptPrompt too longCut to the six slots, around 120 characters

Genre starting points

Prefer to copy a known-good recipe? Each of these is the starting prompt from its genre guide — paste it into the style box, then adjust one tag at a time:

LO-FI
lo-fi hip-hop, warm and nostalgic, dusty rhodes piano, mellow jazz guitar, soft boom-bap drums, vinyl crackle, 75 bpm, instrumental, tape saturation, gentle sidechain
HOUSE
house, warm and hypnotic, four-on-the-floor kick, deep rolling bassline, soulful vocal chops, warm analog pads, crisp off-beat hats, 124 bpm, club mix
ROCK
classic rock, energetic and anthemic, distorted power chords, crunchy overdriven lead guitar, punchy live drums, driving bass guitar, gritty male vocal, 128 bpm, big live-room mix

Frequently asked questions

What should go in Suno's style box versus the lyrics box?

The style box holds comma-separated descriptors: genre, mood, instrumentation, vocal style, tempo and production fx. The lyrics box holds the words plus bracketed section markers like [Chorus] and parenthetical backing vocals. Keep structural directions out of the style box.

Does the order of tags in a Suno prompt matter?

Yes. Suno weights earlier tags more heavily, so lead with the genre and mood that define the song and trail the finer production details. Reordering the same tags can noticeably change the result.

How long should a Suno style prompt be?

Concise wins. Although the field accepts up to about 1,000 characters, tight prompts of roughly 120 characters of well-chosen tags track more reliably than long, vague ones.

Does Suno understand BPM?

Yes. Writing the tempo as a number, such as 92 bpm, is one of the most reliable ways to control speed in Suno. For trap and similar styles, use around 140 bpm with a half-time feel rather than a low number.

How do I make an instrumental track in Suno?

Add the tag instrumental to the style box and leave the lyrics box empty, or use only section markers such as [Intro] and [Instrumental Break] with no words.

How do I stop Suno singing words like verse or chorus?

Put section markers in square brackets inside the lyrics box, for example [Verse] and [Chorus], and keep them out of the style box. Unbracketed section names can be sung as lyrics.

Why does Suno ignore part of my prompt?

Usually the prompt is too long, uses vague words like epic or good, or mixes too many genres. Cut it back to one genre, one mood, two to four instruments, one vocal style, a BPM and one or two production tags.
