Csus4 Chord

Csus4 holds F, the fourth, where a major chord would use its third. Letting that fourth move to the third is the small release to listen for.

Where does Csus4 belong?

The fourth takes the third's place, making Csus4 useful as a brief delay before the major chord.

Progressions to try

  • FCsus4CF

    Hold Csus4 before the ordinary major chord on the same root; the suspended note then resolves into the third.

  • CCsus4C

    The home chord briefly becomes Csus4 and releases without changing the bass.

Which shape should you use?

On guitar, start with the open x33011 grip. Let the open strings ring and keep any strings marked x silent. The x33563 shape gives you another position when the neighboring chords sit elsewhere on the neck.

On ukulele, the open shape 0013 is the easiest place to start. The 5533 grip moves the chord to another register.

On piano, play C-F-G. Move C up an octave to reach the first inversion, F-G-C; the notes remain the same while the lowest voice changes.

What are the inversions?

C is the root, F the fourth and G the fifth. There is no third in this chord.

  • Root position: C-F-G, with C lowest.
  • First inversion: F-G-C, written Csus4/F if F is lowest in the whole arrangement.
  • Second inversion: G-C-F, written Csus4/G if G is lowest in the whole arrangement.

A slash chord names the note in the bass, not merely the lowest note under one hand. Chord Inversions shows how to read that distinction.

How does Csus4 differ from C?

Keep C and G while F moves down to E. That resolves Csus4 into C; the root and fifth never moved. Try that one-note change on piano, then use the comparer to hear it in the full chord. See C for the other chord's full spelling and roles.
