About the Csus4 Chord
The Csus4 chord creates immediate, palpable tension that yearns for resolution. Built from C-F-G, this suspended chord replaces the major third with the perfect fourth, creating a sound that leans forward, wanting to fall into C major. This resolution tendency has made sus4 chords staples in rock, pop, and classical music.
What makes Csus4 distinctive is its directional energy. While sus2 chords float ambiguously, sus4 chords feel like they're pulling toward something. The perfect fourth (F) in Csus4 wants to fall down to E, resolving the tension into a satisfying C major chord.
On piano, Csus4 is wonderfully accessible—C, F, and G are all white keys in a comfortable span. The resolution from Csus4 to C (moving F down to E) is one of the most satisfying gestures in keyboard playing.
Music Theory & Usage
Csus4 functions primarily as a tension chord that resolves to C major. The gesture Csus4-C appears constantly in rock, creating forward motion and release. In classical harmony, sus4 (also called a "4-3 suspension") is a fundamental voice-leading technique.
The chord also works as a modal color, particularly in Mixolydian contexts. Some songs stay on Csus4 without resolving, using its tension as a stable foundation.

Frequently Asked Questions about Csus4
What notes are in Csus4?
Csus4 contains C (root), F (perfect 4th), and G (perfect 5th). The fourth replaces the third, creating suspension. All white keys on piano.
Why does Csus4 feel like it needs to resolve?
The fourth (F) in Csus4 is a dissonance against the root. In traditional harmony, the fourth "wants" to fall to the third (E), resolving the tension. This pull creates Csus4's forward energy.
What's the difference between Csus4 and Csus2?
Csus4 (C-F-G) has the fourth replacing the third; Csus2 (C-D-G) has the second. Csus4 feels tense and directional (wants to resolve down); Csus2 feels open and ambiguous (floats without direction).
Can Csus4 resolve to C minor?
Yes! Csus4 can resolve to C minor (moving F to Eb) instead of C major (moving F to E). This creates a minor resolution that's equally satisfying but more melancholic.
