What notes are in the C Suspended 4th chord?

The C Suspended 4th chord is built from C4 F4 G4. By scale degrees that is 1 · 4 · 5 — in other words root · perfect 4th · perfect 5th (0 · 5 · 7 semitones above the root C). The root of the chord is C, and the other tones are stacked above it in thirds.

What gives the C Suspended 4th chord its sound?

A suspended 4th chord, written sus4, holds a gentle tension. It swaps the third of a chord for a note five semitones above the root — the 4th scale degree — which sits just a semitone above where the major third would be. That closeness makes the ear want the 4th to ease down into the 3rd, so a sus4 always feels as though it is reaching toward a major chord.

Sus4 chords are the sound of hymns, anthems and the famous 'Amen' cadence, and they give rock songs their yearning, suspended quality before a big resolution. They hold your attention without ever sounding dissonant. Play C sus4 here, let it linger, then resolve to C major — the 4th falling to the 3rd is one of the most natural moves in all of music.

That single habit builds the muscle memory behind almost every song you will ever play.
