Read left to right, 6th string to 1st: a number is a fret, 0 is an open string, x is a string you do not play.
- Index finger on the 1st fret of the B string (2nd).
- Middle finger on the 3rd fret of the A string (5th).
- Ring finger on the 3rd fret of the D string (4th).
- Little finger on the 3rd fret of the high E string (1st).
- Let the G string ring open.
- Do not play the low E string: start the strum from the A string.
String by string
What each string does in this shape, and which note of the chord it sounds. This is what to listen for when you pluck them one at a time.
| String | Fret | Finger | Note | In the chord |
|---|---|---|---|---|
| 6th (low E) | not played | — | — | — |
| 5th (A) | fret 3 | middle | C3 | root |
| 4th (D) | fret 3 | ring | F3 | fourth |
| 3rd (G) | open | — | G3 | fifth |
| 2nd (B) | fret 1 | index | C4 | root |
| 1st (high E) | fret 3 | little | G4 | fifth |
One string at a time: a chord strummed into a microphone is several notes at once, and a single string is something the page can hear exactly. A string in tune but on the wrong fret, or deadened by the finger beside it, shows up here and not on a tuner. Tap a string to check it again.
3 other ways to play Csus4
The same 3 notes, somewhere else on the neck. A different shape puts a different note on top, so each one colours the chord slightly differently — and one of them is usually nearer the chord you are coming from.
- x33563A barre at the 3rd fret and two more fingers
- 8-8-10-10-8-8A barre at the 8th fret and two more fingers
- 88556xA barre at the 5th fret and three more fingers
If the usual shape is too hard for now
x33011 is Csus4 without the full barre — fewer strings, the same chord. It is a real voicing, not a cheat, and plenty of players keep using it.
Holding it cleanly
One string rings open next to fretted ones. Arch the fingers so they come down on their tips — a finger lying flat will deaden the open string beside it, and the chord loses a note without sounding obviously wrong.
The lowest string is left out, because its open note is not in the chord. Aim the strum to start below it, or let the tip of a fretting finger rest against the unwanted string to keep it quiet.
The notes in Csus4
A suspended fourth chord is built from the root (1), 4 and 5 of its root’s major scale. From C that gives C – F – G. The third is pushed up to the fourth. It leans back down to the plain major chord, and is usually played just before it.
The same root, other chords: C major, Cm, C7, Cmaj7, Cm7, Csus2, Cdim, Caug.
Frequently asked questions
What notes are in a Csus4 chord?
C suspended fourth is three notes: C – F – G — the root, 4 and 5 of the C major scale. On guitar the shape x33013 sounds C3, F3, G3, C4 and G4, so some of those notes appear more than once.
What is the easiest way to play Csus4 on guitar?
The usual shape is x33013 — an open-position shape, with four fingers. If that is out of reach for now, x33011 is the same chord without the full barre.
What is the difference between Csus4 and C?
Csus4 replaces the third of C with the fourth (F). The fourth leans back down to the third, so Csus4 is nearly always followed by C.
