Spell it as D♭sus2 in flat keys
In written music this chord often appears as D♭sus2. The shapes and sound are identical — only the name changes with the key.
No open strings
C#sus2 has no open-string voicing in standard tuning, so every shape is fretted. The A-shape barre at fret 4 is the most dependable starting point.
Use it as a moveable shape
The x-4-6-6-4-4 barre is fully moveable — slide it down a fret for Csus2 or up a fret for Dsus2.
Resolve to the major chord
C#sus2 wants to fall back to C# major. Practising C# → C#sus2 → C# trains your ear to hear the suspension release.
Keep the barre firm
A clean A-shape barre needs steady index pressure across the top five strings. Roll the finger slightly toward its bony side for a stronger barre.
About the C#sus2 Chord on Guitar
The C#sus2 chord is built from three notes: C# (the root), D# (the major 2nd), and G# (the perfect 5th). It is a C# major triad with the 3rd suspended — the E# is replaced by the D# a whole step above the root — so it sounds open and neutral rather than clearly major. Because none of its notes line up with open guitar strings, every C#sus2 voicing is fretted, which makes it good practice for moveable shapes. C#sus2 is enharmonically identical to D♭sus2 — same pitch, same shapes, different spelling depending on the key. This page covers two voicings: a moveable A-shape barre and a top-four-string form. Every diagram is interactive and playable with acoustic guitar sound.
