Ask for the words
The lyric track starts a transcription of the vocal stem — a model that runs on your machine, downloaded once.
Lyrics when you want them
A chord chart without the words is half a chart. Jambox transcribes the vocal into timed lines, runs them under the chords on the same playhead, and lets you correct anything the model misheard.

Read along in time
Each line carries its own slice of the song, and the unit being sung is lit as the playhead reaches it.
Fix what it misheard
Double-click a line and type the right words; the correction is what the track, the sheet and the PDF carry.
What you get
- Timed lines under the chords
- Word-level highlighting as the song plays
- The same words on the lead sheet and in the PDF
Where it stops
Lyrics are transcribed from the vocal: an instrumental has none, and a dense mix, a heavy accent or a language the model has not seen will need corrections. The model is a one-time download, because a transcription needs a network the first time.
Questions
Does it work in my language?
The model handles many languages, including Chinese, Japanese, Korean and the European ones this site speaks. A language it has not seen is where hand editing earns its keep.
What happens to a song with no vocals?
There is nothing to transcribe, so the sheet prints the chords and the instrumental sections on their own.
Can I type my own lyrics?
Yes. A line is editable, and an edited line is not overwritten when the track is drawn again.

Your language, built in
The whole interface is translated, and the menu names every language in itself — 日本語, 简体中文, Español — instead of making you read English to find yours.
Five-stem separation
Every track splits into five — guitar, drums, bass, vocals and piano — so you can hear your part alone, or drop it out and play over the rest.
Chord recognition
JamAI, our own chord engine, transcribes the progression and shows it in sync with the song.
