The idea in one sentence

Take the five most-used open chords (C, A, G, E, D), turn them into movable barre shapes, and you have a complete map of every major chord in every position on the neck. The same five shapes also organize the major scale and pentatonic scale into five connected boxes. CAGED is the framework that ties chords and scales together.

Why these five specifically

C, A, G, E, and D are the only five open major chords on a standard-tuned guitar. (B and F don't have a true open shape — they require a barre.) Each of the five places the chord's three notes (root, 3rd, 5th) in a different configuration on the strings. When you barre them and move them up the neck, between them they cover every possible inversion of a major chord across all six strings.

The five shapes as movable chords

Each shape, barred at the right fret, becomes a major chord whose name depends on where the root lands. Here are all five shapes producing the SAME chord — D major — at five different positions on the neck:

The interlocking order

The shapes always cycle in the order C → A → G → E → D → C as you climb the neck. From any starting position, the next shape up shares two notes with the previous one — that's why they 'interlock' instead of sitting in isolated chunks.

Starting from open C: the next C up the neck is the A-shape barred at fret 3. Then the G-shape at fret 5. Then the E-shape barre at fret 8. Then the D-shape at fret 10. Then back to the C-shape at fret 12 (one octave above where you started). Five shapes, twelve frets, every position covered.

Minor variants

Each of the five shapes has a minor cousin. The most useful minor barres are the E-shape minor (e.g. Fm at fret 1, Gm at fret 3) and the A-shape minor (Bm at fret 2, the classic 'Bm barre' shape). The D-shape minor exists too (the tiny Dm shape moved). C-shape minor and G-shape minor are awkward and rarely used in practice.

Scales pair with shapes

Each CAGED chord shape has a matching scale 'box' built around it. The E-shape barre at fret 8 (for D major) sits inside the scale box that gives you all the D-major notes from fret 5 to fret 11. The A-shape barre at fret 5 sits inside the next scale box up. Memorize one chord shape and one scale box together, and you have everything you need to play rhythm and lead in that position.

This is the practical payoff: when you switch shapes to move from one position to another, the scale box moves with you. Soloing across the neck stops being 'where am I now?' and becomes 'which CAGED zone am I in?'

Why it matters

• Find any major chord anywhere on the neck — five options per chord, pick whichever is closest to your hand.
• Compose voicings high or low for textural variety (low chords are heavy; high chords are bell-like).
• Solo with confidence: each shape comes with its own scale box.
• Switch between rhythm and lead without changing positions — the scale lives inside the chord shape.
• Read 'V/V' or 'play it up the octave' and instantly know five places to do it.

Practice this week — the CAGED ladder

• Pick one chord (say, G major). Find it in all five CAGED shapes: open G (G-shape), A-shape barre at fret 10, then climb back down — E-shape at fret 3, D-shape at fret 5, C-shape at fret 7. Strum each shape twice; move smoothly between them.
• Now do the same for C major: open C (C-shape), then A-shape at fret 3, G-shape at fret 5, E-shape at fret 8, D-shape at fret 10. Five shapes, all C.
• Once you can climb the chord, climb the scale: play C major scale in each CAGED position. By week's end you'll have the neck mapped.
• Apply it to a song: play 'Wonderwall' (Em–G–D–A) using only chords from frets 5-12. The same song, an octave up, sounds completely different — that's CAGED giving you variety from material you already knew.
