Quick answer

Updated

Kenerate's AI song extender makes a song longer by continuing it — pick a song in your Music Studio library, write the lyrics for the new part and choose where the continuation starts, and Extend (Mureka V8) generates the rest in the same style and voice. In our tests a 31-second clip became 1:20 and 2:45 full songs. Extend works on songs you made in the studio; a new account gets 25 free credits.

    Lyrics for the extension: [Verse 2] Porch light's glowing at the end of the lane Smell of cinnamon and the coming rain Every step I take, the leaves call out my name Autumn's walking me home again [Chorus] Walk me home, walk me home, through the gold and red Walk me home, walk me home, every word you said

Anatomy

What Extend adds

The original keeps playing up to the start point; from there the extension continues with the lyrics you wrote.

  1. Original: intro + hook · 12 barsYour finished clip, up to the start point
  2. New verse · 8 barsLyrics you add — same voice
  3. New chorus · 8 barsRepeat your hook for a real song shape
  4. More · 8 barsExtend again for a bridge or outro

Choose the start point just before the clip's ending so the join sounds natural — 25 seconds into a 31-second clip worked well in our tests.

Prompt recipe

How to extend well

Three inputs decide how the join sounds.

1
The start point
Just before the original ends — before any fade-out.
2
The new lyrics
A verse and a chorus with [Verse]/[Chorus] tags; match the original's line length.
3
Reuse the hook
Repeat the original chorus line so it feels like one song.
4
Extend again
Each extension is a new song you can extend further.

Tips

Seamless extensions

From our extension tests.

  • Start the extension before any fade-out, not at the very end.
  • Keep the new lines about as long as the original's lines.
  • Repeat the original hook in the new chorus.
  • Extend in steps: verse + chorus first, then a bridge and outro.
  • Ken Music 1 clips (~30 s) are a cheap way to test ideas before extending.
  • For a long track without vocals, ElevenLabs Music can also make an exact length up to 10 minutes directly.

In depth

AI Song Extender, explained

What works, what to avoid, and how the pieces fit.

Why extend instead of regenerating

Regenerating a longer song gives you a different song. Extending keeps what you already like — the voice, the melody, the hook — and adds to it. That's why short clip engines like Ken Music 1 pair well with Extend: find a hook you love in 30 seconds, then build the full song around it.

Writing lyrics for the extension

The extension sings exactly what you give it, so:

  • Match the meter — similar syllable counts per line as the original.
  • Continue the story — verse 2 should move forward, not restart.
  • Echo the hook — reuse the chorus line from the original.
  • Use tags — [Verse 2] and [Chorus] tell it which part is which.
