The CAGED System: Five Shapes to Rule the Fretboard
Introduction
The CAGED system is the most powerful fretboard visualization tool. It divides the neck into five overlapping zones based on C, A, G, E, and D shapes.
By understanding how these shapes connect, you gain complete fretboard navigation.
The Five Shapes
The C Shape
The C shape produces a C major chord in open position. Root on the 5th string.
The A Shape
The A shape is compact and versatile. Root on the 5th string.
The G Shape
The G shape is wide and full, using all six strings. Root on the 6th string.
The E Shape
The E shape is the most widely used movable form. Root on the 6th string.
The D Shape
The D shape is compact and bright, using only four strings. Root on the 4th string.
How the Shapes Connect
Each shape’s highest root note becomes the next shape’s lowest root. The chain of shapes covers the entire fretboard with no gaps.
Finding Chord Voicings
For any chord, locate the root and identify which CAGED shape applies. Each voicing has a different character—some bright, some warm.
CAGED and Scales
Every CAGED shape corresponds to a scale position. The five scale positions give you a complete map of any major scale.
CAGED and Arpeggios
The shapes are also arpeggio patterns. Knowing them lets you target chord tones precisely.
Practical Applications
Chord Substitution
Use different CAGED voicings for the same chord. This adds harmonic variety.
Voice Leading
Connect chords by moving between nearby CAGED shapes. This smooth voice leading creates professional progressions.
Solo Construction
Target notes from the CAGED arpeggio matching the underlying chord. This chord-tone soloing sounds intentional.
Practice Routine
- Shape mastery: Learn each CAGED shape in all five positions.
- Connect the shapes: Play C-A-G-E-D for a single chord up the neck.
- Scale integration: Play the major scale through each CAGED position.
- Song application: Play a song using different CAGED voicings.
Conclusion
The CAGED system is your fretboard GPS. Once internalized, you’ll never feel lost on the neck again.
