Navigating the guitar fretboard can often feel like exploring a vast, uncharted territory. Unlike the linear layout of a piano, the guitar’s grid-like structure, while offering unique versatility, can initially seem complex and confusing. Many guitarists find themselves struggling to visualize note relationships and patterns across the neck, hindering their ability to improvise, compose, or even simply play in different keys and positions. If you’ve ever wished for a system to bring clarity and order to the fretboard, allowing you to effortlessly connect different areas of the neck, the CAGED system is your answer.
The CAGED system is a powerful and intuitive method for understanding and mastering the guitar fretboard. It provides a logical framework for recognizing chord shapes, scale patterns, and arpeggios all over the neck. By learning the CAGED system, you’ll transform the seemingly random collection of frets into a cohesive and easily navigable landscape, unlocking new levels of musical freedom and expression on the guitar.
Decoding the CAGED System: How It Works
The beauty of the CAGED system lies in its simplicity and reliance on familiar concepts. It leverages the five fundamental open chord shapes – C, A, G, E, and D – to divide the guitar fretboard into five interconnected, manageable sections. This system reveals the underlying relationships between these common chord shapes and the arrangement of notes and intervals across the fretboard.
Once you grasp these relationships, the fretboard ceases to be an overwhelming maze of notes. Instead, you begin to perceive it as a collection of interconnected shapes and patterns that seamlessly link together. This visual and conceptual framework drastically simplifies fretboard navigation and opens up a world of possibilities for guitarists of all styles.
Let’s delve deeper into the core components of the CAGED system – the five chord shapes that form its foundation.
The Foundational Chords of the CAGED System
The CAGED system is aptly named as it is constructed upon five basic open chord shapes:
- C chord
- A chord
- G chord
- E chord
- D chord
These five open chord forms are not just static shapes; they are movable templates. This means that each shape can be transposed and played in different positions along the fretboard. Typically, this transposition is achieved by using a barre to replace the nut, effectively shifting the open chord shape up the neck.
While some of these barre chord shapes, particularly the E and A forms, might already be familiar to you as common barre chords, understanding their origin within the CAGED system provides a deeper insight into their structure and application.
First, let’s examine each of these shapes in their open form, the building blocks of the system. Then, we will explore how to move these shapes up and down the fretboard to create different chords and navigate the entire neck.
CAGED Open Chord Shapes: The Building Blocks
These open chord shapes are the fundamental building blocks upon which the entire CAGED system is constructed. They are movable shapes, meaning they can be shifted up and down the neck to create different chords while maintaining the same underlying shape and intervallic relationships.

The power of the CAGED system lies in the movability of these shapes. By understanding how to transform these open shapes into barre chords, you unlock the ability to play chords in multiple positions across the fretboard. Let’s explore each shape and its barre chord transformation.
The C Form
Alt text: CAGED C form barre chord diagram showing how the open C chord shape is barred to create a movable chord form up the guitar neck.
Starting with the open C chord, if you move this shape up two frets, you create a D chord in the C form. Because the C form is no longer in the open position, you need to barre across strings 1, 2, and 3 at the second fret to maintain the integrity of the chord shape. This barre effectively replaces the nut, allowing you to transpose the C chord shape.
The A Form

By moving the open A chord shape up to the 2nd fret and barring across all strings at the 2nd fret, you form a B chord in the A form. This is a very common and versatile barre chord shape that is essential to master.
The G Form
Alt text: CAGED G form barre chord diagram showing how the open G chord shape is adapted to create a movable chord form, often omitting the high E string note.
Moving the G chord shape up to the 6th fret, and adapting it into a barre chord, gives you a B♭ chord in the G form. Notice that fingering the root note on the 1st string in this shape can be challenging. It’s a common practice to omit this top note, especially when playing in a band context, without significantly altering the chord’s sound.
The E Form

Moving the E chord shape up to the 2nd fret and barring across all strings at the 2nd fret creates a familiar F# barre chord. The E form barre chord is perhaps the most widely used and recognized barre chord shape on the guitar, and understanding its place within the CAGED system reinforces its importance.
The D Form
Alt text: CAGED D form chord diagram showing how the open D chord shape is shifted and barred to create a movable chord form higher up the guitar neck.
By moving the open D chord shape up three frets and adapting it into a barre chord, you get an F chord in the D form. This shape often involves barring strings 2, 3, and 4, with the root typically found on the 4th string.
Connecting the CAGED Shapes Across the Fretboard
The true power of the CAGED system emerges when you understand how these movable chord shapes connect and relate to each other across the entire fretboard. The system logically maps out the fretboard because any chord can be played in multiple positions using the CAGED chord forms. Furthermore, each chord shape seamlessly transitions into the next, following a cyclical pattern: C-A-G-E-D.
- C form connects to A form
- A form connects to G form
- G form connects to E form
- E form connects to D form
- D form connects back to C form, and the pattern repeats
Let’s trace the C major chord up the fretboard to illustrate how these shapes interlock.
We start with the open C major chord, the foundational C form.
The root note on the 5th string of the C form chord also serves as the root note for the A form chord shape when playing a C major chord. Observe how the C form naturally leads into the A form in the diagram below, showcasing an A form C major chord.

The 5th, root, and major 3rd intervals located on the 4th, 3rd, and 2nd strings of the A form C chord, respectively, form the upper portion of the G form chord shape. This connection seamlessly links the A form C chord to the G form C chord.
The root note on the 6th string of the G form C chord is shared with the E form CAGED shape, providing the connection between the G and E forms. Below, you’ll see the familiar E form C barre chord, with its root note on the 8th fret.

By utilizing the root note on the 4th string of the E form C chord, we can transition from the E form to the D form C chord shape.
Finally, the D form C chord connects back to the C form C chord through the 5th, root, and major 3rd intervals on the 3rd, 2nd, and 1st strings, completing the CAGED cycle.

These diagrams visually demonstrate the interconnectedness of the CAGED chord forms across the entire fretboard. Remember that these chord forms are applicable to any root note. The following example diagram illustrates the D major chord played across the fretboard using the CAGED shapes, showing the system’s versatility.
Root Notes: Anchors of the CAGED Chord Shapes
Once you become comfortable with the CAGED chord shapes themselves, the next crucial step is to internalize the location of the root notes within each shape. Each CAGED chord shape has a unique root note pattern that distinguishes it from the others. These root notes act as anchor points, enabling you to quickly identify and access the chord shapes across the neck, regardless of the chord’s root.
