How to Write Suno AI Prompts: Styles, Tags & Lyrics Guide

Suno doesn’t take one prompt — it takes two, working together: a Style field that shapes the sound, and a Lyrics field that holds the words and structure tags. Treating them as one blended description is the single biggest reason Suno output comes out generic. This guide covers how to use each field properly, plus the v5.5 features worth knowing about.

What’s New in Suno v5.5

• Rebuilt vocal engine and 48kHz output. Noticeably more natural-sounding vocals and full-quality audio export.
• True stem export. Pull out individual instrument and vocal tracks instead of only a mixed final file.
• Songs up to 8 minutes. With structurally coherent lyrics that hold together across the full runtime, not just the first verse and chorus.
• Voice cloning and Custom Models. Train the AI on your own voice or build a specialized model tuned to one genre or style.
• My Taste. A profile that learns your musical preferences and steers generations toward them automatically.

Writing the Style Field

Suno weights the first words of the Style field most heavily, so lead with genre and tempo, then layer in the rest: mood and energy, vocal character, key instruments, and production quality. A strong Style field looks like dense, comma-separated description rather than a sentence — for example: “bright modern pop, 118 BPM, upbeat and confident, breathy female vocals, synth bass and clean electric guitar, polished radio production.”

Specificity matters more than length. “Synth-pop” consistently outperforms “pop,” and “raspy male vocals” outperforms “male vocals.” Aim for 3-6 strong descriptors rather than a long list of weak ones.

Writing the Lyrics Field

The Lyrics field should contain only your actual words plus structure tags — nothing about style or instrumentation belongs here. Place each section tag on its own line directly above the lyrics it applies to:

• [Verse] — standard verse section, typically 4-8 lines.
• [Pre-Chorus] — builds tension heading into the chorus.
• [Chorus] — gets the most energy and melodic emphasis from Suno; keep it 2-4 lines so the hook stays tight.
• [Bridge] — a contrasting section, often a melody or key shift.
• [Outro] — where Suno winds the energy down, sometimes fading out.

More lines per section means a faster delivery of the lyrics, so keep verses and choruses tight if you want a natural, unhurried pace.

Example Prompt Pair

Style: indie folk, 92 BPM, wistful and warm, soft male vocals, fingerpicked acoustic guitar, light strings, no drums

Lyrics:

[Verse]
Four lines about leaving a small town behind
…
[Chorus]
Two to four lines, the emotional hook of the song
…
[Outro]
A line or two that lets the energy settle

Common Mistakes

• Mixing style description into the Lyrics field. Keep instrumentation and mood notes in the Style field only — it keeps your results repeatable.
• Vague, single-word genre tags. “Pop” or “rock” alone gives Suno too little to work with; add a subgenre and a reference point.
• Only generating one version. Suno’s output is probabilistic — generate 3-5 versions of a prompt you like before judging whether it works.
• Overloading a single section with too many lines. This rushes the delivery and throws off the song’s natural pacing.

FAQ

What’s the difference between the Style and Lyrics fields?

Style controls the sound — genre, mood, instruments, tempo. Lyrics holds only the words and structure tags like [Verse] and [Chorus]. Keeping them separate produces far more consistent results.

How long can a Suno song be?

Up to 8 minutes with Suno v5.5, with structural coherence maintained across the full length.

Do I need to write full song lyrics myself?

No — you can describe the theme and let an AI writing tool draft the lyric structure for you first. Try WePrompt’s free Prompt Generator to turn a plain description into a usable starting point.
