🎸 Guitar Practice Companion
Pick a key and work through the theory, scales, and shapes that go with it.
Key:
1. Notes in the Key
The seven diatonic chords built on each scale degree, with quality and scale-degree number.
2. Open Position Chords
Best available low-fret voicing for each chord in the key. Not every key has a true "open" (nut) shape — some show a low-position voicing instead.
3. Scales & Arpeggios
Major Scale
Major Pentatonic
Relative Minor Pentatonic
Arpeggios (each diatonic chord)
4. Barre Chords
Each chord shown as a movable E-shape (root on the low E string) and A-shape (root on the A string) barre chord.
5. CAGED System
Pick a chord from the key, then see all 5 CAGED shapes (C, A, G, E, D) moved to that chord's root.
6. Random Chord Progression
Generates 4 chords drawn from the key so you can practice changing between them.
