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 flat across the top 5 strings, from the A string up at the 4th fret — the barre.
- Middle finger on the 6th fret of the G string (3rd).
- Ring finger on the 7th fret of the B string (2nd).
- 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 4 | index | C♯3 | root |
| 4th (D) | fret 4 | index | F♯3 | fourth |
| 3rd (G) | fret 6 | middle | C♯4 | root |
| 2nd (B) | fret 7 | ring | F♯4 | fourth |
| 1st (high E) | fret 4 | index | G♯4 | 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 C♯sus4
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.
- 9-9-11-11-9-9A barre at the 9th fret and two more fingers
- x4412xA shape at the 1st fret · four fingers
- 99667xA barre at the 6th fret and three more fingers
If the usual shape is too hard for now
Or use a capo: clamp it at the 4th fret and play the Asus4 shape. Every string is raised 4 semitones, so that open shape now sounds C♯sus4.
Holding it cleanly
The barre is the hard part. Lay the index finger just behind the 4th fret, roll it slightly onto its bony outer edge, and keep the thumb behind the neck opposite it. Pluck the barred strings one at a time: a buzz or a dead string means the finger is not flat there yet.
It spans 4 frets. Bring the elbow in and let the hand turn slightly toward the body of the guitar; the stretch comes from the hand opening, not from the fingers reaching.
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 C♯sus4
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, C♯m, C♯7, C♯maj7, C♯m7, C♯sus2, C♯dim, C♯aug.
Frequently asked questions
What notes are in a C♯sus4 chord?
C♯ suspended fourth is three notes: C♯ – F♯ – G♯ — the root, 4 and 5 of the C♯ major scale. On guitar the shape x44674 sounds C♯3, F♯3, C♯4, F♯4 and G♯4, so some of those notes appear more than once.
What is the easiest way to play C♯sus4 on guitar?
The usual shape is x44674 — a barre chord at the 4th fret, with a barre at the 4th fret and two more fingers. Or put a capo on the 4th fret and play the Asus4 shape, which then sounds C♯sus4.
Is C♯sus4 the same chord as D♭sus4?
Yes — on guitar they are the same frets and the same sound. C♯ and D♭ are two names for one pitch, and which name a songbook prints depends on the key: a piece in a sharp key writes C♯sus4, a piece in a flat key writes D♭sus4.
What is the difference between C♯sus4 and C♯?
C♯sus4 replaces the third of C♯ with the fourth (F♯). The fourth leans back down to the third, so C♯sus4 is nearly always followed by C♯.
