Map pentatonic positions, CAGED shapes, playable chord voicings, and real chord progressions on one interactive fretboard. Free to use, fast to explore, and built to help guitar players connect theory to the neck.
Start with the pentatonic scale — the foundation of rock, blues, and country guitar — and go as deep as you want. FretScope is a free interactive guitar fretboard trainer that grows with you, from your first pentatonic position all the way to advanced modes, CAGED shapes, and chord voicings.
See all 5 CAGED positions for major and minor pentatonic across the full neck — and exactly how they connect, so you stop being locked into one box and start playing the whole fretboard.
Drag the position window to any fret region — single shapes or multi-position windows spanning several shapes — and see how scales, chords, and arpeggios all connect in any key.
Instantly map major, natural minor, pentatonic, blues, Dorian, Mixolydian, Phrygian, Lydian, and more across all 22 frets in any root key.
Switch to Chord mode and see playable voicings for major, minor, dominant 7, major 7, minor 7, sus2, sus4, diminished, power, and more across the CAGED system.
Type a progression and click through each chord. The fretboard highlights chord tones as triads or 7ths inside the active shape, so scale practice turns into real phrasing.
Dorian, Mixolydian, Phrygian, Lydian, Locrian, and more become easier to understand when you can see exactly where the characteristic notes live on the neck.

Most guitarists learn one pentatonic box shape and stay there for years. FretScope shows how all five positions connect across the neck so players can move instead of getting trapped.
A guitar scale chart shows which frets and strings belong to a scale in a given key. Traditional charts are static images. FretScope updates live as you change the root note, scale type, or position.
The most effective approach is to connect scales to chord shapes and chord tones. FretScope links every scale degree to the underlying harmony so players can see what matters inside the shape.
The CAGED system organizes the guitar neck into five repeating shape patterns derived from open chord shapes moved up the neck. Understanding these positions is a force multiplier for scales, chords, and arpeggios.
Modes make more sense when the changing notes are visible on the fretboard. FretScope helps players compare major, minor, Dorian, Mixolydian, and more inside familiar position windows.
Type a progression, click through each chord, and watch the chord tones move in real time. That makes it much easier to practice melodic soloing instead of just running scales.
