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.
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.
Three-note chords and other shapes
A triad is a three-note chord. A voicing is one way to arrange a chord's notes on the guitar. Use Chord mode to compare playable shapes and fingerings, or choose Three-note shapes for smaller patterns.
