The CAGED System: Unlock the Entire Guitar Fretboard
The CAGED system is one of the most powerful concepts a guitarist can learn. It takes five open chord shapes you already know — C, A, G, E, and D — and shows you how to use them as a map of the entire fretboard. With the CAGED system, you can play any chord, scale, or arpeggio in any position on the neck.
In this guide, we'll break down how the CAGED system works and how to use it to transform your playing.
What Is the CAGED System?
The CAGED system is based on a simple observation: the five basic open chord shapes (C, A, G, E, D) can be moved up the neck as barre chords. When you arrange these shapes in the order C-A-G-E-D, they connect to each other like puzzle pieces, covering the entire fretboard for any given chord.
Here's the key insight: each shape connects to the next. The C shape flows into the A shape, which flows into the G shape, and so on. After the D shape, it loops back to C — one octave higher.
The Five Shapes
- C shape — based on the open C chord
- A shape — based on the open A chord (the A-shape barre chord)
- G shape — based on the open G chord
- E shape — based on the open E chord (the E-shape barre chord)
- D shape — based on the open D chord
The name "CAGED" comes from the order of these shapes as they appear on the fretboard.
How the CAGED System Works
Let's trace the CAGED system using a G major chord as an example.
Shape 1: C Shape (G major)
Take the open C major chord shape (x32010) and move it up the neck so the root is on G. The root of the C shape is on the 5th string, so move it to the 10th fret (where G is on the 5th string). Barre with your index finger at the 10th fret, and form the C shape with your other fingers.
Shape 2: A Shape (G major)
Move down from the C shape position to the A shape. The A shape barre for G major is at the 10th fret on the 5th string (root on 5th string at the 10th fret). This is the A-shape barre chord you probably already know.
Shape 3: G Shape (G major)
Continue along the neck to the G shape. The root of the G shape is on the 6th string. For G major, the G shape barre is at the 3rd fret (root on 6th string at the 3rd fret — that's the open G chord moved up... actually for G major, the G shape IS the open G chord at the 3rd fret area).
Actually, let me simplify. For a G major chord:
- G shape: Open G chord (3rd fret area) — this is where the name comes from
- E shape: Barre at the 3rd fret (E-shape barre chord for G)
- D shape: Around the 5th-7th frets (D-shape voicing)
- C shape: Around the 7th-10th frets
- A shape: Barre at the 10th fret (A-shape barre chord for G)
The five shapes overlap and connect, covering every position on the fretboard where a G major chord can be played.
The Five CAGED Shapes in Detail
The C Shape
Based on: Open C chord (x32010)
Root location: 5th string (and 2nd string)
Barre: Index finger acts as the nut
The C shape is often underused because it's awkward to finger as a full barre chord. But it's extremely useful for partial voicings — playing just the top 4 strings of the shape gives you a beautiful, compact chord.
The A Shape
Based on: Open A chord (x02220)
Root location: 5th string
Barre: Index finger barres across the fret
This is one of the two barre chord shapes most guitarists learn first. The full shape uses a ring-finger barre across three strings for the major triad, but many players use individual fingers or just the top notes.
The G Shape
Based on: Open G chord (320003)
Root location: 6th string (and 3rd string, 1st string)
Barre: Index finger barres across the fret
The G shape is the most difficult to finger as a full barre chord, but its partial voicings are excellent. Playing just strings 1-4 of the G shape gives you a useful triad voicing.
The E Shape
Based on: Open E chord (022100)
Root location: 6th string (and 4th string, 2nd string)
Barre: Index finger barres across all 6 strings
This is the other barre chord shape most guitarists learn first. It's the most common shape for rock and blues rhythm guitar. The minor version (based on Em) is equally important.
The D Shape
Based on: Open D chord (xx0232)
Root location: 4th string (and 2nd string)
Barre: Index finger barres the top 4 strings
The D shape only covers four strings, making it more compact. It's commonly used for triad-based rhythm playing and for finding chord tones high on the neck.
Why the CAGED System Matters
1. Fretboard Navigation
Before the CAGED system, the fretboard can seem like an undifferentiated grid of notes. After learning CAGED, you see five interconnected zones, each based on a familiar shape. You always know where you are and where to go next.
2. Chord Vocabulary
Instead of knowing one or two ways to play a chord (open position and one barre shape), CAGED gives you five positions for every chord. You can choose the voicing that best fits the musical context.
3. Scales and Arpeggios
The CAGED shapes aren't just for chords — they also organize scales and arpeggios. Each CAGED position has a corresponding scale fingering and arpeggio pattern. This means learning CAGED gives you chord, scale, and arpeggio knowledge simultaneously.
4. Connecting Positions
CAGED teaches you how to move between positions smoothly. Instead of being stuck in one area of the neck, you can travel up and down the fretboard connecting one shape to the next.
5. Improvisation
When soloing, CAGED gives you multiple positions to play from. You can start a solo in one position, then shift to the next CAGED shape to move up or down the neck — all while staying in key.
How to Practice the CAGED System
Step 1: Master the Five Open Chords
Make sure you can play all five open chords (C, A, G, E, D) cleanly. These are the foundation of the entire system.
Step 2: Convert Each to a Movable Shape
Practice turning each open chord into a movable barre chord. Start with the E shape and A shape (the easiest), then work on C, G, and D shapes.
Step 3: Trace One Chord Through All Five Shapes
Pick a chord (e.g., G major) and find all five CAGED shapes on the fretboard. Play each one, noting how they connect:
- G shape → E shape → D shape → C shape → A shape → G shape (one octave up)
Step 4: Connect Adjacent Shapes
Practice moving smoothly between adjacent CAGED shapes. For example, play a G chord using the E shape, then slide to the D shape for the same G chord. The goal is to see how the shapes overlap and connect.
Step 5: Apply to a Progression
Take a chord progression (e.g., G - C - D) and play it using different CAGED positions. For example:
- Play all chords using E shapes
- Play all chords using A shapes
- Mix shapes: G (E shape) → C (A shape) → D (C shape)
Step 6: Add Scales
For each CAGED position, learn the corresponding major scale fingering. This gives you five scale positions that correspond to your five chord shapes.
CAGED for Minor Chords
The CAGED system works for minor chords too. Each major shape has a minor version (based on the minor open chord):
- C shape → Cm shape (based on Cm, which isn't a standard open chord, but the concept applies)
- A shape → Am shape (based on open Am)
- G shape → Gm shape (based on Gm)
- E shape → Em shape (based on open Em)
- D shape → Dm shape (based on open Dm)
The minor shapes follow the same C-A-G-E-D order and connect the same way.
Common CAGED Mistakes
1. Only Learning Chords
CAGED is often taught only as a chord system, but its real power is in organizing scales and arpeggios too. Make sure you learn the scale and arpeggio patterns that correspond to each CAGED shape.
2. Memorizing Without Understanding
Don't just memorize the shapes — understand how they connect. The key is seeing how the root note of one shape becomes the connecting point to the next shape.
3. Not Applying to Music
Practicing CAGED shapes in isolation is like learning vocabulary without writing sentences. Apply CAGED to real songs and solos to make it musical.
4. Forgetting Partial Voicings
You don't always need to play the full 6-string version of each shape. Partial voicings (playing 3-4 strings of a CAGED shape) are often more useful and sound better.
How Revoz Relates to CAGED
Revoz uses the same principles that CAGED teaches — movable chord shapes, inversions, and smooth connections between positions:
- Movable voicings: Revoz suggests voicings across the entire fretboard, not just open position or one barre shape
- Inversions: Each CAGED shape is essentially a different inversion or position of the same chord — Revoz considers all of these when finding the best voice leading
- Smooth connections: Just as CAGED teaches you to connect adjacent shapes, Revoz finds the smoothest path between chords, minimizing hand movement
- Multiple options: Revoz shows you multiple voicing options for each chord, similar to how CAGED gives you five positions
Conclusion
The CAGED system is the master key to the guitar fretboard. It takes five shapes you already know and shows you how they interconnect to cover every position on the neck. With CAGED, you can play any chord in any position, find scales and arpeggios anywhere, and navigate the fretboard with confidence.
The journey to mastering CAGED takes time, but it's one of the most rewarding investments you can make in your guitar playing. Start by tracing one chord through all five shapes, then gradually add scales, arpeggios, and minor chords. Before long, you'll see the fretboard not as a confusing grid of notes, but as five interconnected zones that you can navigate effortlessly.
