How to write lyrics for AI-generated songs

Short, even lines, clear section tags and a chorus that repeats are what make generated vocals sound natural.

Last reviewed 21 October 2026

When you paste lyrics into a song generator, the model has to fit every word to a melody and a rhythm. Lyrics written with that in mind come back sounding sung; lyrics written like prose come back rushed or garbled.

Mark the sections

Put each section under a tag on its own line: [Intro], [Verse], [Pre-Chorus], [Chorus], [Bridge], [Outro]. The tags tell the generator where the energy should rise and fall, so verses sit back and the chorus lifts. In the Sonvela composer you can insert them with one click in Custom mode.

Keep lines short and even

  • Aim for roughly 6 to 10 syllables per line in verses and fewer in the chorus.
  • Keep lines in the same section close in length, so they fit the same melody.
  • If a line is much longer than its neighbours, split it in two.

Long, uneven lines are the most common reason generated vocals sound crammed.

Give the chorus a hook and repeat it

A chorus works when people can sing it after one listen. Use one short line as the hook, repeat it at least twice, and keep the chorus wording identical each time it returns. Repetition also gives the generator a stable melody to come back to.

Rhyme loosely, stress naturally

Rhymes at the ends of lines help the phrasing land, but near rhymes are fine. Read each line aloud: if the natural stress falls on a weak word, rewrite it so the important word lands on the beat.

Leave space

Not every bar needs words. A short [Intro] or an instrumental break before the last chorus gives the arrangement room to breathe and makes the vocal feel deliberate.

Match lyrics to the style

Rap verses can carry many more syllables per line than a ballad. Write tight, rhythmic lines for hip hop and drill, longer held vowels for soul and gospel, and simple, open lines for pop and folk. Our genre pages describe how vocals usually work in each style.

Common mistakes

  1. Pasting a poem without sections, so the song has no chorus to return to.
  2. Writing paragraphs instead of lines.
  3. Changing the chorus words every time, which weakens the hook.
  4. Using names or brands you do not have the right to use in a commercial song.

A starting template

If you would rather not write lyrics at all, leave the box empty and describe what the song is about. See how to write prompts for AI music.
