Familiar section labels steer form. They do not guarantee bar counts. Repeat the chorus words you want remembered.
Start with the labels Suno documents.
Suno’s current songwriting guidance recommends structure tags such as [Intro], [Verse] or [Verse 1] and [Verse 2], [Pre-Chorus], [Chorus], [Bridge], and [Outro]. Put each label on its own line. These labels organize the lyric sheet and signal intended flow.
They do not lock exact form, duration, or delivery. A [Chorus] label communicates your intended section. It does not promise eight bars, identical melody, or the same ad-libs every time. If exact length matters, use editing tools after generation.
A dependable vocal song often follows a familiar path: Verse, Pre-Chorus, Chorus, Verse, Chorus, Bridge, Chorus, Outro. Adapt the path to the genre. Do not invent a poetic label when a familiar one already names the job.
Write empty labels for a full song using only the documented set. Check that each section has a reason to exist.
Keep local modifiers rare and audible.
A colon-modified label is a practical community pattern, not a documented command language: [Verse 1: close-mic, sparse drums] or [Chorus: full low end, stacked responses]. Use two or three compatible cues. If the cue applies to the whole song, move it to Style.
Name the instrument in a break rather than writing a decorative tag. [Guitar Solo] or [Instrumental Break: piano] tells the section what to do. [Cosmic Rebirth Portal] does not.
Extra labels such as Interlude, Build, Drop, or Whisper can be tested as descriptive requests. Their behavior is not a documented command contract. Prefer a familiar label plus an observable delivery over a private code.
[Verse 1: close-mic, sparse drums] The kitchen light is still on I leave the tap running just to hear it [Pre-Chorus: rising, filtered instruments] I almost say your name then I let it fall [Chorus: fuller band, stacked responses] Don’t wake the room (don’t wake the room) Let the night keep us quiet
Write lines a mouth can hold.
Keep lyric lines short and conversational. Long lines get rushed. Neighboring lines should stay near the same length unless a stretch is the point. Write numbers as words when they must be sung. Repeat the chorus exactly if you want the hook to come back as itself.
Verse 2 should advance the story. The bridge should reframe, confess, reverse, or intensify. The last chorus pays off the same hook rather than introducing a new title. One quotable line is enough; cleverness that never lands in the mouth is not a hook.
You can experiment with parentheses such as (answer me) to request a response, echo, or ad-lib. They can still be sung as ordinary lyrics, so never treat them as hidden instructions. Write vocalizations such as ooh, whoa, or mmm in the lyric sheet when you want to request them.
Punctuation is a light cue. Ellipses, commas, dashes, and exclamation marks may affect breath or emphasis, but they are not duration or rhythm notation. Patterns of dots and bangs cannot specify a dependable beat.
Write a four-line chorus. Read it aloud in time. Split any line that you cannot say in one breath. Copy the same chorus under a second [Chorus] label.
Know what a tag cannot do.
Section labels steer a probabilistic model. They are not a DAW. [8 bars] does not reliably produce eight bars. Capital letters do not make a tag stronger. More tags do not mean more control when they compete.
Gender or role tags do not always switch singers cleanly. If a duet matters, separate the sections clearly and describe the two deliveries. Use recordings you have permission to work with when a specific performance matters; a text prompt does not establish a particular singer’s identity.
When you need exact timing, use Replace Section, Extend, Studio, or a DAW. Save the lyric sheet with the Style line that supports it. If a tag asks for a huge chorus, Style should not also demand a sparse whisper for the whole song.
Keep exploring.
