The Csus2 chord on guitar: open shapes and barre

Csus2 is C with the third taken out and a D put in its place. The result is neither happy nor sad: it floats. On guitar it is also one of the friendliest chords to play, because two of its three notes ring on open strings. Learn x30013 first, then hear what it does next to a plain C, and you will start finding places for it in songs you already know.

Csus2 chord: notes and shapes at a glance

  • Name: C suspended second
  • Symbol: Csus2
  • Notes: C, D, G

Each shape below is written from the thickest string to the thinnest: a number is the fret, 0 an open string, x a string you do not play. New to this? See how to read chord diagrams.

Shape Frets, low E to high E Notes, low to high What it is for
Csus2, open x30013 C D G C G The standard open Csus2: C on the fifth string, D and G ringing open.
Csus2, open (high D) x30033 C D G D G Same chord with D on top as well: a little brighter, and a common alternative fingering.
Csus2, four strings x3553x C G C D A movable shape with no open strings. Useful when you need a tighter, more controlled sound.
Csus2, barre x35533 C G C D G The A sus2 shape barred at the third fret. Slide it anywhere: the root is on the fifth string.
Csus2, open x 3 0 0 1 3 · 3 · · 1 4 fingers
Csus2, open (high D) x 3 0 0 3 3 · 2 · · 3 4 fingers

Read each diagram from the thickest string on the left to the thinnest on the right. A cross means the string is not played, a circle means it rings open.

Csus2 on the neck: every C, D, G

Standard tuning, frets 0 to 12. The highlighted notes are the notes of Csus2: any shape you build from them, anywhere on the neck, is still Csus2.

How to play Csus2, step by step

1. The open shape: x30013

Third finger on the fifth string (A) at fret 3: that is C, the root. First finger on the second string (B) at fret 1, another C. Fourth finger on the high E at fret 3, which gives G. Leave the fourth and third strings open: they give D and G. Start the strum on the fifth string.

2. Check the open D

The open fourth string is the note that makes this chord a sus2. If the third finger leans on it, the D dies and you are left with a thin C power chord. Pick the strings one by one, arch the third finger, and listen for the D before you strum.

3. The variant: x30033

Move the note on the second string from fret 1 to fret 3. Now the second string gives D instead of C, so the chord has D twice and a brighter top. Both versions are Csus2; pick the one that is easier to reach from the chord before.

4. Movable: x35533

Barre the first finger across fret 3 from the fifth string down, third finger on the fourth string at fret 5, fourth finger on the third string at fret 5. The second and first strings stay on the barre. This is the A sus2 shape (x02200) moved up three frets, so it works for any sus2 with the root on the fifth string.

Keep the low E silent in every shape. E is the third of C, the one note a sus2 chord leaves out on purpose.

Csus2 next to C, Cm and Cadd9

The quickest way to understand Csus2 is to play it beside its neighbors. Only one note changes each time.

Chord Shape Notes What you hear
C x32010 C, E, G The major third E: settled and bright.
Cm x35543 C, Eb, G The minor third Eb: darker.
Csus2 x30013 C, D, G No third at all: open, waiting.
Cadd9 x32030 C, E, G, D The third is back, with D added: rich, not suspended.

Csus2 and Gsus4 share the same three notes, C, D and G. When the bass is C and the song lives around C, the chord is a Csus2. See also the pages for C, C minor and Cadd9.

Where to use Csus2

Csus2 is a color, not a replacement for every C. It works best where the music has room to breathe: an intro, the last bar of a phrase, a slow strum. These are the moves to practice, four beats per chord at first.

Change Shapes What to listen for
C, Csus2, C x32010, x30013, x32010 E drops to D and comes back. The third finger stays put on the fifth string.
Csus2, C, Am, G x30013, x32010, x02210, 320003 Open the loop with the suspension, then let C settle it.
C, Csus2, G, F x32010, x30013, 320003, xx3211 Csus2 shares D and G with the G chord that follows it.
Csus2 and Csus4 x30013 to x33011 Two suspensions around the same C: second, then fourth.

Its sibling, with F in place of D, is on the Csus4 page. The same idea on D lives on the Dsus2 page.

Common Csus2 mistakes

Mistake Why it matters The fix
Strumming the low E E is the third Csus2 leaves out, and it muddies the bass. Start the strum on the fifth string.
Muting the open D D is the note that makes the chord a sus2. Arch the third finger and play the strings one at a time.
Leaving the high E open x30010 adds E: with E and D together it is a Cadd9 sound, not Csus2. Keep the fourth finger on fret 3 of the first string.
Squeezing too hard The hand tires and the notes go sharp. Fingers close to the fret wire, thumb relaxed behind the neck.

Frequently asked questions

How do you play Csus2 on guitar?
The usual shape is x30013: third finger on the fifth string at fret 3, first finger on the second string at fret 1, fourth finger on the high E at fret 3. The fourth and third strings ring open. Do not play the low E string.
What notes are in a Csus2 chord?
C, D and G. C is the root, D the second, G the fifth. There is no third, so no E and no Eb.
Is Csus2 major or minor?
Neither. Major or minor is decided by the third, and a sus2 chord replaces the third with the second. That is why Csus2 sounds open and unresolved, and why it can stand in for C or Cm depending on what is around it.
Is Csus2 the same as Cadd9?
No. Cadd9 keeps the E and adds D on top: C, E, G and D. Csus2 drops the E entirely. If the open high E string rings over your C shape, you are playing an add9 or a C with an extra note, not a Csus2.
What is the difference between Csus2 and Gsus4?
On paper, none: both contain C, D and G. The name depends on which note the music treats as home. In a song that sits on C, with C in the bass, you call it Csus2.

Guitar Social Club is the work of Yohann Abbou, a guitar teacher in Paris who teaches adults. Every shape on this page is written string by string and checked against standard tuning, and the diagrams are drawn from those same fret numbers.
