What the tool adds
Extend Song uses the source audio and your written direction to create a continuation. Treat the result as another version to listen to, not an automatic final edit. The source gives the continuation musical context, but the fit can vary. Listen at the join and check the voice, timing, harmony, and energy before keeping it.
Ask for a specific kind of continuation:
- •Intros
- •Bridges
- •Instrumental breaks
- •Outros and endings
- •A longer version of an existing section
Use it when you want to: Lengthen a short track - Test a different arrangement shape - Try an intro, bridge, or ending before editing the full track - Hear a possible next section before rebuilding it elsewhere
From source song to continuation
2. Describe what comes next
State the section, mood, instruments, vocals, and direction you want:
- -Intro
- -Bridge
- -Outro
- -Section extension
- -A longer continuation
Length depends on the source and model. Model V5 supports tracks up to 8 minutes.
3. Listen at the join
Review how the continuation follows the source track's:
- -Tempo
- -Harmony
- -Instrumentation
- -Style
Keep the continuation only if the transition and new section serve the song. Another prompt or a manual edit may fit better.
What you control
The continuation point
Choose where the source should hand off to the new section.
The next musical move
Describe the section, instruments, vocal direction, and energy you want.
Which result to keep
Review the transition and discard a continuation that does not fit.
The later edit
Take the chosen version into the rest of your writing or production process.
Useful reasons to extend a song
Test a missing bridge
Hear whether a contrasting section gives the chorus more weight.
Try a longer ending
Explore an outro or instrumental passage without changing the source first.
Open with a new section
Test an intro that prepares the listener for the existing track.
Continue an unfinished draft
Use the current song as context for the next verse or section.
Compare arrangement options
Generate a continuation, then compare it with the shorter structure.
Before you extend a song
How long can I extend my song?
Length depends on the source and model. Model V5 supports tracks up to 8 minutes; earlier models support up to 4 minutes.
What types of sections can I add?
Ask for an intro, bridge, outro, instrumental break, new verse, or a longer version of an existing section.
Will the extension match my original style?
The source track provides context, but the match can vary. Check the transition, voice, tempo, harmony, and instrumentation before keeping the result.
Do I need music production experience?
No. You can create a continuation from written direction, but your ears still decide whether it fits and whether it needs another edit.
What source files can I use?
Choose a completed song from your Wsong.ai library or upload an MP3 up to 100 MB. Only upload audio you have the right to process.
Continue with other Wsong.ai tools
Extend the version worth keeping, then separate parts only if the next edit needs them.
