The fretboard and CAGED
CAGED is the idea that the five open chord shapes you learned first (C, A, G, E, and D) are not just beginner grips. Slid up the neck and barred, those same five shapes spell every major chord, in order, over and over. Learn how they connect and the whole fretboard opens up.
Five shapes, one neck
Pick any key. Its root note appears in five places along the strings before the pattern repeats at the twelfth fret. Each of those places is the anchor for one of the five shapes. Play them in the order C, A, G, E, D going up the neck and each shape's ending lines up with the next shape's beginning. They interlock like puzzle pieces.

Five shapes. One neck. Pick a key and watch the C, A, G, E and D forms tile the fretboard: the same chord, five places, all connected.
The idea
You already know the open C, A, G, E and D chords. The CAGED system's big insight is that these five shapes are moveable: slide any of them up the neck and it becomes a new chord. Stack all five for one key and they tile the entire fretboard, connecting end to end. That's what this board shows: the same chord, five positions, no gaps.
How to read it
Each color is one shape; the flags above the board show where each shape sits. A ringed marker is the root, the note the chord is named after. In scale views, solid markers are chord tones (your safe landing spots) and hollow markers are passing tones. A split-color marker belongs to two shapes at once: those shared notes are the doorways between positions.
How to practice
Start with one shape on and play the chord tones until the pattern is automatic. Add its neighbor and walk between them through the shared notes. Then switch to a scale view and solo inside one box, landing on solid markers. When all five feel like home, change the key. The shapes stay the same, they just slide.
Every marker is a chord tone of G major. Rings mark the root. Where two shapes share a note, the marker splits. That seam is how you move between positions.
Why the order never changes
The sequence C, A, G, E, D is fixed because it follows the distance between the shapes' root notes, and that distance is the same in every key. Only the starting fret moves. That is the whole trick: memorize one order, and you can find any chord anywhere.
From chords to scales
Each shape also carries a piece of the scale around it. When you can see the shape, the scale notes sit right next to your fingers. Turn on the scale overlay below and watch the major scale and pentatonic boxes grow out of the same five anchors. This is why lead and rhythm stop feeling like separate skills.
How to practice it
Do not try to swallow all five at once. Pick one key. Learn the E shape and the C shape and the move between them. Add G, then A, then D. Say the shape name out loud as you land it. Within a week the neck starts to feel like a map instead of a grid of dots.
