The guitar feels like it has a million chord shapes. The CAGED system says: there are five. Every other shape is a moved version of one of these.
CAGED stands for the five open-chord shapes you already know: C, A, G, E, D. The trick: each shape is movable. Slide the E shape up two frets, you get F#. Slide the C shape up two frets, you get D.
Read the diagram. Each colour is one CAGED shape, all playing C major in different positions. The dot pattern of the open C chord appears at the nut. Then the A shape appears at fret 3 (an A shape, slid up to make C). Then G shape at fret 5. Then E shape at fret 8. Then D shape at fret 10. Then back to C shape at fret 12 (an octave higher).
Why this matters
Three big payoffs:- Connect the neck. The same chord lives in five places. The five pentatonic shapes you will learn later? They live inside the same five CAGED positions.
- Play any chord anywhere. Need C# in a song where every other chord is around the 9th fret? Use the C-shape barred at fret 1, or the A-shape at fret 4, or the G-shape at fret 6. Don't jump to fret 1.
- Solo over chords. Knowing which CAGED shape underlies a chord tells you which scale notes to target for that chord.
How to practice this
Pick one chord (C is a great start). Memorize the five positions slowly. Move from one shape to the next on the neck. Strum each. They all sound like C, just in different octaves and textures.Do not try to memorize all five shapes on day one. Get the first two solid (C at the nut, A shape barred at fret 3) before adding the G shape. Then E shape. Then D.
This is a system that takes months to internalize. Spend 10 minutes a day for a month and it will start to click.
Also works for minor
Same five positions, minor flavour. Roughly the same shapes with the third dropped a half step.
