Why it sounds like that

C♯ suspended 2nd is built from the formula 1, 2, 5. The major 2nd between C♯ and D♯ replaces the major 3rd of C♯ major, creating an open, unresolved sound. The perfect 5th anchors the chord.

What goes wrong with C♯ suspended 2nd?

  • Letting the E string ring out; mute it with the fretting-hand thumb.
  • Pressing the G string too hard and bending it sharp.
  • Collapsing the ring finger onto the C string fret 8 and deadening the A string.

When to use it

C♯ suspended 2nd works as a passing chord in C♯ major progressions like C♯–F♯–G♯–C♯ (I–IV–V–I). It suits rock and pop strumming where the suspended 2nd adds tension before resolution. Use it before C♯ major to delay the tonic.

Changing to and from C♯ suspended 2nd

  • Move to C♯ major by lifting the index finger from the G string and placing it on the C string fret 8, keeping the middle finger on the A string fret 6.
  • Slide the whole shape down two frets to the 4th fret to play B suspended 2nd.

Which voicing to use

The 6th fret shape puts C♯ in the bass and is the most direct voicing. The C♯sus2/D♯ inversion at frets 8-8-9-× gives a lower, darker sound with D♯ in the bass. Choose the C♯sus2/D♯ inversion when you want the 2nd in the bass for a suspended feel.

Common questions

How is C♯ suspended 2nd written?

C♯ suspended 2nd is written C♯sus2 or C♯. On a keyboard, use C# as the ASCII root. It is also spelled D♭ in enharmonic notation for the same sounding root.

How does C♯ suspended 2nd differ from C♯ add 9?

C♯ suspended 2nd replaces the 3rd with the 2nd, so it has no major or minor quality. C♯ add 9 keeps the major 3rd and adds the 2nd on top, giving a fuller major sound.

Can C♯ suspended 2nd resolve to C♯ minor?

Yes, C♯ suspended 2nd can resolve to C♯ minor because the 2nd (D♯) moves down to the minor 3rd (E). The lack of a 3rd in the sus2 makes the resolution smooth.
