Writing lyrics for AI songs: sections, syllables and cues

Published 1 October 2026 - 7 min read

When you write your own lyrics in the Composer, the engine follows your words closely. A little structure makes the difference between a song that flows and one where the singer rushes or stretches lines.

Label every section

Start each section with a label in square brackets: [Intro], [Verse 1], [Pre-Chorus], [Chorus], [Bridge], [Outro]. Labels tell the engine how to treat the section - a chorus gets more energy and a fuller arrangement, a bridge often changes the mood. Each Composer section has its own duration, styles and lyrics.

One sung line per line

Put each phrase on its own line. Four to eight words per line is a comfortable range for most tempos; long lines get crammed in. Up to 30 lines fit in a section, but most verses work best with four.

Give sections enough time

As a rule of thumb at a mid tempo:

  • A four-line verse needs about 15 to 25 seconds.
  • A chorus of two to four lines needs 10 to 20 seconds.
  • An instrumental intro or break: 4 to 10 seconds.

If the singer sounds rushed, lengthen the section or cut a line. If there is a long gap with no singing, shorten it or add an instrumental cue.

Repeat the hook

Real songs repeat. Reuse the same chorus lyrics each time it comes around - the engine treats repetition as the hook and the song feels finished rather than wandering. A short, singable title line in the chorus is the most reliable way to make a track memorable.

Use braces for short cues, styles for the big picture

Inline cues in curly braces steer a moment: {guitar solo}, {drums drop out}, {whispered}. Broader characteristics - genre, instruments, vocal type - belong in the section styles instead. The first section's styles matter most because they set the sound of the whole song, so give it six or seven.

Example section

[Chorus]
Turn the radio up tonight
Hold the moment, hold it tight
{big drums come in}
We are golden in the light

Other languages

Lyrics can be written in many languages, including Spanish, German, French, Portuguese and Japanese. Keep the styles in English (the engine requires it) and add the language as a style too, for example "Spanish vocals".

Your words, your responsibility
