Where the capo can go
1 – 5 – 6 – 4, smoothest voicings
Teal dots are fingers that stay planted from the chord before.
This is the real engine, cut down to one progression. The full tool does any progression in any key, with 860+ checked voicings to explore.
What it fixes
Which fret does the capo go on?
Capo finder. Every capo position that gives you easy shapes for the key, with the chords you finger and the chords the band hears.
My chord changes are slow and messy.
Smooth it. One tap picks the voicings where the fewest fingers move, and shows you which ones stay planted.
My progressions sound flat.
Colour voicings. The add9, sus and 7th shapes that make four chords sound like a record.
How it works
B♭, E♭, F: whatever the chart or keys player says.
Capo 3 with G shapes, capo 1 with A shapes. You see what you play and what it sounds like.
Chords are numbered 1, 4, 5, 6m, so a band leader's numbers make sense.
Hear it with a strum pattern at your tempo, before rehearsal.
Add-on for lead players
Box Breaker lights up the whole neck. Pick two boxes and it shows the exact notes they share, so you can slide into the next box mid-phrase.
Only in the Rhythm + Lead bundle.
