Understanding the Csus4 Guitar Chord: Notes and Theory
The Csus4 chord, often written as C suspended 4th, gets its distinctive sound from its internal structure. Unlike major or minor chords which have a third, suspended chords, as the name suggests, “suspend” or omit the third. In the case of Csus4, the third of the C major scale (E) is replaced by the fourth (F).
Therefore, the notes in a Csus4 chord are C, F, and G.
- C – Root (1)
- F – Perfect Fourth (4)
- G – Perfect Fifth (5)
These notes are built using the intervals of Root, Perfect Fourth, and Perfect Fifth.
To understand this further, let’s look at the chord formula for a Suspended Fourth chord:
1 - 4 - 5This formula applies to all sus4 chords, not just Csus4. By replacing the 3rd with the 4th, we create a sound that is neither major nor minor, but has a unique open and unresolved quality. This suspension creates a musical tension that often resolves beautifully to a major or minor chord.

How to Play the Csus4 Guitar Chord: Positions
Now, let’s get practical and explore how to play the Csus4 chord on your guitar. We’ll cover three essential positions, starting with the easiest open position.
Position 1: Open Csus4 Chord
This is the most common and easiest way to play the Csus4 chord, especially for beginners. It utilizes open strings and is a great starting point for mastering this chord.

To play the open Csus4 chord:
- Index Finger (1st fret, B string): Place your index finger on the 1st fret of the B string (2nd string).
- Middle Finger (2nd fret, D string): Place your middle finger on the 2nd fret of the D string (4th string).
- Ring Finger (3rd fret, A string): Place your ring finger on the 3rd fret of the A string (5th string).
- Strum: Strum all strings except the low E string (6th string). Alternatively, you can strum all six strings, as the open low E string doesn’t clash harshly with the Csus4 chord.
This open position Csus4 is perfect for songs in the key of C, G, or F major.
Position 2: Barre Csus4 Chord (Movable Shape)
This position uses a barre chord shape, making it movable up and down the fretboard. This means you can play a sus4 chord with any root note using this shape.

To play the Position 2 Csus4 chord:
- Barre with Index Finger (5th fret): Barre your index finger across all six strings at the 5th fret.
- Ring Finger (7th fret, A string): Place your ring finger on the 7th fret of the A string (5th string).
- Pinky Finger (7th fret, D string): Place your pinky finger on the 7th fret of the D string (4th string).
- Strum: Strum all six strings.
This shape is based on the open Asus4 chord shape barred up the neck. To play a Csus4, you barre at the 5th fret because the 5th fret on the low E string is the note C.
Position 3: Barre Csus4 Chord (Movable Shape)
This is another movable barre chord shape for Csus4, offering a different voicing and feel compared to Position 2.

- Ring Finger (10th fret, B string): Place your ring finger on the 10th fret of the B string (2nd string).
- Strum: Strum from the A string (5th string) down to the high E string (1st string).
This shape is derived from a D shape barre chord and is moved up the neck. Barre at the 8th fret to create a C root.
