Suspended chords, often abbreviated as “sus” chords, add a unique flavor and tension to guitar music. Among these, the Csus guitar chord family, particularly Csus2 and Csus4, are popular for their distinctive sound. Instead of the typical major or minor third, suspended chords feature either a major second (sus2) or a perfect fourth (sus4) interval. This subtle change creates a beautiful, unresolved quality that can be used to add depth and emotion to your guitar playing.
In this guide, we’ll explore the Csus2 chord and Csus4 chord in detail, breaking down their musical theory, the notes that make them, and providing easy-to-read guitar chord diagrams. Whether you’re a beginner just starting to explore beyond basic chords or an experienced player looking to enrich your chord vocabulary, understanding the Csus chord is a valuable step.
Understanding the Csus Chord Family: Suspended 2nd and Suspended 4th
The core concept behind any suspended chord is the “suspension” of the third. In standard major and minor chords, the third interval determines whether the chord is happy (major) or sad (minor). Suspended chords bypass this by replacing the third with a different interval, creating a sound that is neither major nor minor, but hangs in a state of harmonic suspension.
- Csus2 Chord: In the Csus2, the third is replaced by a major second above the root. For a C chord, the major third would be E. In Csus2, this E is moved down to D, which is a major second above C. The notes of a Csus2 chord are C, D, and G.
- Csus4 Chord: In the Csus4, the third is replaced by a perfect fourth above the root. Again, starting with a C chord, the major third E is moved up to F, which is a perfect fourth above C. The notes of a Csus4 chord are C, F, and G.
Both Csus2 and Csus4 chords share the root (C) and the perfect fifth (G) with a standard C major chord. The crucial difference lies in that suspended note, the D in Csus2 and the F in Csus4, which gives each chord its unique sonic character. This replacement of the third is what creates the characteristic “suspended” or unresolved feeling associated with these chords. They often sound like they want to resolve to a major or minor chord, adding a layer of harmonic interest.
Playing the Csus4 Guitar Chord
Let’s dive into how to play the Csus4 guitar chord. The Csus4 is known for its open, airy sound, often described as having a questioning or unresolved quality.
The notes of the Csus4 chord are, as we mentioned, C, F, and G. Here are a couple of common ways to play the Csus4 chord on guitar:
Csus4 Open Chord:
This is a fundamental voicing of the Csus4 and a great starting point for beginners.
- String 6 (E): X (Muted)
- String 5 (A): 3rd fret (C)
- String 4 (D): 3rd fret (F)
- String 3 (G): 0 (Open) (G)
- String 2 (B): 1st fret (C)
- String 1 (e): 1st fret (F)
Csus4 Barre Chord (5th Fret):
For a more powerful and movable Csus4, the barre chord shape is ideal. This shape allows you to play a Csus4 chord starting on the 5th fret, with the root on the A string.
- String 6 (E): X (Muted)
- String 5 (A): 5th fret (C) – Barre with index finger
- String 4 (D): 5th fret (F) – Barre with index finger
- String 3 (G): 5th fret (G) – Barre with index finger
- String 2 (B): 8th fret (F) – Ring finger
- String 1 (e): 5th fret (C) – Barre with index finger
This barre chord is based on the open A shape barre chord, adapted for the Csus4. By moving this shape up and down the neck, you can play other sus4 chords as well.
Exploring the Csus2 Guitar Chord
Now let’s turn our attention to the Csus2 guitar chord. The Csus2 has a brighter, more delicate suspended sound compared to the Csus4. It’s often used to create a sense of gentle movement or anticipation.
The notes of the Csus2 chord are C, D, and G. Here are a couple of common ways to play the Csus2 chord on guitar:
Csus2 Open Chord:
This is a very common and beautiful sounding open voicing for Csus2.
- String 6 (E): X (Muted)
- String 5 (A): 3rd fret (C)
- String 4 (D): 0 (Open) (D)
- String 3 (G): 0 (Open) (G)
- String 2 (B): 3rd fret (D)
- String 1 (e): 0 (Open) (G)
Csus2 Barre Chord (8th Fret):
Just like with the Csus4, you can also play a barre chord version of the Csus2. This shape is based on the open E shape barre chord, moved up to the 8th fret with the root on the low E string.
- String 6 (E): 8th fret (C) – Barre with index finger
- String 5 (A): 10th fret (D) – Ring finger
- String 4 (D): 10th fret (G) – Pinky finger
- String 3 (G): 9th fret (D) – Middle finger
- String 2 (B): 8th fret (C) – Barre with index finger
- String 1 (e): 8th fret (G) – Barre with index finger
This barre chord shape provides a fuller, richer sound for the Csus2 and is also movable, allowing you to play other sus2 chords up and down the fretboard.
Using Csus Chords in Your Music
Csus chords, both Csus2 and Csus4, are incredibly versatile and can be used in a wide range of musical genres. Here are a few ideas on how to incorporate them into your guitar playing:
- Transitions and Resolutions: Csus4 chords, in particular, are often used as transition chords, creating tension before resolving to a C major or C minor chord. The movement from the 4th (F) to the 3rd (E) creates a satisfying resolution.
- Intros and Outros: The open and airy sound of Csus2 and Csus4 chords makes them perfect for intros and outros. They can create a gentle and inviting opening or a lingering and unresolved ending.
- Adding Harmonic Interest: Substituting a standard C major chord with a Csus2 or Csus4 can instantly add harmonic interest to a chord progression. Experiment with replacing C with Csus2 or Csus4 in your favorite songs and see how it changes the feel.
- Fingerpicking and Arpeggios: The open voicings of Csus2 and Csus4 are especially well-suited for fingerpicking patterns and arpeggiated passages, creating beautiful and shimmering textures.
Experiment with different voicings and placements of Csus guitar chords in your songs and progressions. You’ll find that they can bring a unique and expressive quality to your music.
