CAGED Positions

Free interactive guitar fretboard trainer

Learn guitar scales, CAGED shapes, triads, and chord tones visually

FretScope is built for guitar players who want the neck to make sense instead of memorizing isolated diagrams. Choose a key, switch between scale and chord mode, compare CAGED positions, expand neighboring shapes, and see every note across the fretboard with scale degrees, note names, or shape colors.

Interactive guitar scale charts

Map major, natural minor, minor pentatonic, major pentatonic, blues, Dorian, Mixolydian, and other scale sounds in any key.

CAGED and position training

Move through C, A, G, E, and D shape regions, then connect one shape to the next without losing your root notes.

Chord tones over progressions

Enter progressions like I IV V, ii V I, or Em C G D and highlight the chord tones that make solos follow the harmony.

Triads and chord voicings

Use chord mode to compare playable major, minor, seventh, suspended, diminished, augmented, and partial triad shapes.
