Double-click the chord
The chord menu opens on the mark itself, whether you are in the track, the grid or the sheet.
Edit the chords
No recogniser is right about every chord. Jambox lets you correct any of them — by hand, one at a time, through the same menu the app uses for everything — and every view of the song follows the correction.
Download freeHow it works
Choose what it is
Change the root, the quality (major, minor, sus, diminished) or the extension — a seventh, a ninth, a slash bass.
Everything follows
The chart, the lead sheet, the degree names and the exported PDF are all drawn from the same corrected value.
What you get
- Root, quality and extension on every chord
- Degree names that agree with the chord
- Corrections that reach the PDF
Where it stops
Editing changes the chart, not the audio: the recording is untouched. A chord is one label at one moment, so a voicing or a specific inversion is beyond what a chord name can carry.
Questions
Can I add a chord where there was none?
You can change what the analysis found; a missing chord is added by the analysis rather than by hand.
Do my edits survive?
Yes — they are saved with the song, and re-opening the chart shows your version.
Which spelling will it use?
The one the key you are playing in calls for, so a ♭ and a ♯ are chosen by the key rather than by the raw note.

Edit the lyrics
The words are editable too — fix a line the analysis misheard, and the correction is what the track, the sheet and the PDF carry.
Take the song with you
One menu, five ways out: the original stems and your own takes as ZIPs, the whole mix as a WAV, and the chart as an A4 sheet or a grid. All written on your own machine.
Grid
One box per beat, two bars to a row, and the chord printed where it arrives: the box the song has reached is lit, and the chords behind the playhead turn green.
