What Is the CAGED System?

The CAGED system is a framework for understanding the guitar fretboard using 5 open chord shapes: C, A, G, E, and D. These shapes are named after the open chords they are based on.

Every major chord on guitar can be played in 5 different places on the neck, using one of these 5 shapes moved up with a barre. The shapes connect end-to-end along the fretboard in CAGED order, repeating every 12 frets.

Once you know the CAGED shapes, you can play any chord in any key, navigate the neck without getting lost, and understand where your scale positions live relative to each chord shape.

The Key Insight

Every chord shape connects to the next in CAGED order. After the C shape comes the A shape, then G, then E, then D, then C again. If you know where one shape is, you automatically know where all 5 shapes are for that key.

The 5 CAGED Shapes

C
C major (open shape)
Root: B string (open = wrong, use as reference) or A string (3rd fret = C)
Pop, folk, singer-songwriter
Open C shape (frets 0-3)
e (1) | 0 | E
B (2) | 1 | C
G (3) | 0 | G
D (4) | 2 | E
A (5) | 3 | C
E (6) | x | x
Movable Shape
Slide C shape up the neck with a barre. Root = A string.
Solo Connection
C shape pentatonic sits above this chord shape. Same root on A string.
Character
Warm, open sound. The barre version has a distinctive high root on B string.
A
A major (open shape)
Root: A string (open = A) or Low E (5th fret = A)
Rock, blues, country
Open A shape (frets 0-2)
e (1) | 0 | E
B (2) | 2 | A
G (3) | 2 | E
D (4) | 2 | C#
A (5) | 0 | A
E (6) | x | x
Movable Shape
Slide A shape up the neck with a barre. Root = A string.
Solo Connection
A shape pentatonic root on A string. Classic rock solo territory.
Character
Bright, punchy. Barre version is the most common barre chord on guitar.
G
G major (open shape)
Root: Low E (3rd fret = G) or High e (3rd fret = G)
Country, pop, blues, indie
Open G shape (frets 0-3)
e (1) | 3 | G
B (2) | 3 | D
G (3) | 0 | G
D (4) | 0 | D
A (5) | 2 | B
E (6) | 3 | G
Movable Shape
G shape barre is physically demanding. More often used as partial shapes (strings 1-4 or 4-6).
Solo Connection
G shape scales cover the wide fret span. Use partial barre on strings 1-4 for easier fretting.
Character
Full, resonant. Root on both E strings (low and high) makes it easy to spot on the fretboard.
E
E major (open shape)
Root: Low E (open = E) or A string (7th fret = E)
Rock, metal, blues, punk
Open E shape (frets 0-2)
e (1) | 0 | E
B (2) | 0 | B
G (3) | 1 | G#
D (4) | 2 | B
A (5) | 2 | E
E (6) | 0 | E
Movable Shape
E shape barre is THE most common barre chord. Slide to any fret. Root = low E string.
Solo Connection
E shape pentatonic root on low E. Foundation of every rock solo position.
Character
Powerful, full-range. The movable E shape barre chord covers every key on the low E string.
D
D major (open shape)
Root: D string (open = D) or A string (5th fret = D)
Pop, rock, folk
Open D shape (frets 0-3)
e (1) | 2 | F#
B (2) | 3 | D
G (3) | 2 | A
D (4) | 0 | D
A (5) | x | x

Movable Shape
D shape barre on strings 1-4. Root = D string (or B string partial shapes).
Solo Connection
D shape scale sits on the high strings. Great for melodic lead lines above the 7th fret.
Character
Bright treble-string tone. The most compact CAGED shape. Easiest to play high up the neck.

How the Shapes Connect: G Major Example

Here is how all 5 CAGED shapes cover the full neck for G major. Each shape connects directly to the next with overlapping notes.

How to find any shape in any key
  1. Detect the key with BeatKey (or identify by ear)
  2. Find the root note on the low E string (the chromatic scale gives you fret numbers)
  3. Play the E shape barre with root on that fret
  4. Move up to find the D shape, then C, then A, then G shape as you go up the neck
  5. Use the table above to know what pentatonic position sits inside each shape

How to Use CAGED for Solos
  1. Find the chord being played (using the CAGED shape)
  2. Identify which pentatonic position sits inside that chord shape
  3. Solo using the pentatonic position notes within that chord shape area
  4. Move to the adjacent CAGED shape when you want to shift position on the neck

CAGED Arpeggios

Each CAGED shape also defines an arpeggio (root, 3rd, 5th only). Arpeggios are the strongest possible choice over any chord.

ShapeArpeggio Notes (C major)Best UseTechnique
CC E G (open position)Rhythmic strumming arpeggios, fingerpickingFingerpick p-i-m-a pattern
AC E G (A string root)Lead arpeggio runs, sweep pickingSweep pick ascending/descending
GC E G (low E root)Full-range arpeggio spanning neckTwo-hand tapping or sweep
EC E G (low E string)Classic rock arpeggio patternAlternate pick or sweep pick
DC E G (high strings)Treble-string lead arpeggiosAlternate pick, easy to legato

CAGED for Minor Chords

The CAGED system applies to minor chords too. The 5 shapes become Am, Em, and Dm open shapes (C minor and G minor barre shapes exist but are less commonly named in the minor CAGED system).

The most important minor shapes are:

  • Em shape (movable): root on low E string. Used for ALL minor barre chords starting on the low E string.
  • Am shape (movable): root on A string. Used for ALL minor barre chords starting on the A string.
  • Dm shape (movable): root on D string (high strings only). Less common but useful for high-neck voicings.

CAGED Tips and Common Questions

🎸
Should I learn all 5 shapes at once?
No. Start with E shape and A shape barre chords only. These 2 shapes cover every key. Add the other shapes once you are confident moving between E and A shapes.
🎵
How does CAGED help my soloing?
Each CAGED shape tells you exactly which pentatonic position to use. Over a G major chord, find the nearest CAGED shape for G and play the corresponding pentatonic position inside it.
🔗
Is CAGED the same as the 5 pentatonic positions?
They are related but not identical. CAGED shapes define chord voicings. The 5 pentatonic positions overlap with CAGED shapes but also include notes outside the chord. Together they give you complete fretboard coverage.
Why does the G shape feel so awkward?
The G shape spans a wide fret range and is physically demanding as a full barre. Most players use partial G shapes (strings 1-4 or strings 4-6) rather than the full 6-string barre. This is normal.
🎯
How do I find D major using CAGED?
D major: E shape fret 10, A shape fret 5, G shape fret 7, D shape open, C shape fret 2. The open D chord is the D shape for D major. Each of the other shapes gives you D major in a different neck position.
7️⃣
Can I use CAGED for 7th chords?
Yes. Each CAGED shape has a corresponding 7th chord (major 7, minor 7, dominant 7). The same shape framework applies: E7 shape barre, A7 shape barre, etc. The chord theory changes but the fret positions remain the same.

6 Practice Tips for the CAGED System

1
Start with E and A shape barres only
Learn every key in E shape (root on low E) then in A shape (root on A string). These 2 shapes cover every key and are the most useful.
2
Memorize the chromatic scale on the low E string
E0 F1 F#2 G3 Ab4 A5 Bb6 B7 C8 Db9 D10 Eb11 E12. This tells you the fret for any E shape barre chord root.
3
Practice connecting adjacent shapes
Play a chord in E shape, then slide up to the next shape (D shape) on the same root. Practice this for G, A, C, and D major.
4
Solo inside the CAGED shape
Choose one CAGED chord shape. Solo using only the pentatonic notes inside that shape. Then move to the adjacent shape and continue the solo from there.
5
Use a backing track in one key
Play a I-IV-V or I-vi-IV-V progression. Move through all 5 CAGED shapes for the I chord (root chord) from open to fret 12.
6
Detect the key before you practice
If practicing over a song or sample, use BeatKey to identify the key first. Then start with the CAGED shape nearest to the lowest position on the neck.

Frequently Asked Questions

What is the CAGED system on guitar?

The CAGED system is a framework for learning the entire guitar fretboard using 5 open chord shapes: C, A, G, E, and D. Every major chord can be played in 5 different positions on the neck using these shapes moved up with a barre. The shapes link together in CAGED order across the fretboard, giving you complete coverage of all 12 keys in every position.

How do you use the CAGED system to play G major in 5 positions?

For G major: G shape (open, frets 0-3), D shape (frets 3-7, root on D string fret 5), C shape (frets 5-8, barre), A shape (frets 7-11, root on A string fret 10), E shape (frets 10-15, root on low E fret 3 or 15). Each shape covers a different section of the neck and connects to the next shape.

What is the easiest CAGED shape to learn first?

Start with the E shape barre chord. Move the open E major chord shape up the neck with a barre to play any major chord: fret 1 = F, fret 3 = G, fret 5 = A, fret 7 = B, fret 8 = C, fret 10 = D. The root is always on the low E string. The A shape barre (root on A string) is the second most important shape to learn.

How does the CAGED system connect to scales?

Each CAGED shape has a matching pentatonic scale position. E shape connects to pentatonic Position 1, A shape to Position 2, G shape to Position 3, D shape to Position 4, C shape to Position 5. When you know which CAGED chord shape you are playing, you immediately know which scale position to solo in.
