The most visual, interactive guitar theory companion. Scales, chords, CAGED system, and real chord progressions — all connected, all in one place.
Major, minor, all 7 modes, pentatonic, blues, whole tone, and diminished. Every scale shows its formula, degrees, and up to 5 position boxes.
From basic triads to 13th jazz chords. Every chord shows curated, physically playable fingering diagrams across open, mid, and high neck positions.
A full guide to all 5 shapes with interactive fretboard overlays. See exactly where each shape sits for your key and how they connect across the neck.
20 named progressions across Pop, Rock, Blues, Jazz, and more. Hit Play and hear real guitar audio as the fretboard updates live with every chord change.
Lock to any of 5 scale position boxes and the fretboard dims everything outside your box. Practice one position at a time without getting lost.
Hear every chord played back with real sampled guitar notes. Tap any chord in the library or let the progression player cycle through at your BPM.
Voicings sourced from real guitar pedagogy — open chords, barre chords, and jazz shapes across the full neck. Not algorithmically generated. Actually playable.
The CAGED system links 5 repeating shapes that cover the whole neck. Once you know all 5, you can play any chord or scale anywhere — in any key, at any fret.
20 progressions across every genre. Hit Play and hear real guitar audio while the fretboard shows you every chord shape in sequence.
