The toolkit

Everything connects.

01

Practice

Live

Chord tones across the fretboard. Pick a key, pick a progression, hit play. Intervals light up over each chord. Diatonic, modal, borrowed — all visual.

02

Changes

Live

Build progressions by ear. A suggestion engine ranked by tone distance, not theory labels. Every chord in the chromatic universe, smooth to surprising.

03

Shapes

Coming soon

Every voicing for any chord. Algorithmically generated, works across tunings, ranked by playability. Not a chord dictionary — a chord engine.
