The CAGED system, explained
CAGED uses the five open chord shapes — C, A, G, E and D — as movable templates that tile the fretboard. What it is, why it works, and how to use it for chords, scales and arpeggios.
What CAGED is
Every guitarist knows five open major chords: C, A, G, E, D. CAGED is the observation that each of those shapes can be moved up the neck as a barre chord, and that when you do, the five shapes connect end to end and cover the entire fretboard for any one chord.
Play a C chord. Now play the same C major chord using the A shape at the 3rd fret, then the G shape at the 5th, the E shape at the 8th, the D shape at the 10th. Five positions, one chord, no gaps. That is the whole system.
Why the shapes fall in that order
The order C-A-G-E-D is not arbitrary. Each open shape's root sits on a particular string, and moving up the neck, the next shape is the one whose root lands where the previous shape's highest root was. For a C chord that gives C shape at the nut, A shape at fret 3, G shape at fret 5, E shape at fret 8, D shape at fret 10, and then the C shape again at fret 12. The sequence loops.
- The C shape — its chord, its scale pattern, and where it lands in every key
- The A shape — its chord, its scale pattern, and where it lands in every key
- The G shape — its chord, its scale pattern, and where it lands in every key
- The E shape — its chord, its scale pattern, and where it lands in every key
- The D shape — its chord, its scale pattern, and where it lands in every key
CAGED is for scales too
Around each chord shape sits a scale pattern — the major scale notes that fall under the fingers while holding that shape. Learn the scale pattern that surrounds each of the five shapes and you can play the major scale anywhere on the neck, always anchored to a chord you can see. The same applies to the pentatonic and to arpeggios, which is why CAGED is often the first system a player uses to connect chords and lead lines.
Where CAGED falls short
Its scale patterns are uneven: some strings carry two notes and some three, so the fingering changes shape by string and speed runs are awkward. Players who want fast, symmetrical scale patterns usually move to three-notes-per-string positions, which are built around the scale rather than the chord. The two systems describe the same notes; they just carve the neck up differently. 3NPS vs CAGED, side by side.
How to learn CAGED in a week
- Day 1–2: play one chord — G major — in all five shapes up the neck. Name the shape out loud each time.
- Day 3–4: do the same for the chord's major scale pattern around each shape.
- Day 5–7: pick a second chord and repeat. The shapes are the same; only the frets move.
- Open G major with the E shape highlighted on the fretboard and step through the other four shapes.
