C#sus2 Chord on Ukulele

C#sus2 = C# – D# – G# (Root, Major 2nd, Perfect 5th)

C sharp suspended second reaches its highest point at the fourth fret rather than staying low the way Csus2 does, since none of this chord's three notes happen to land near the nut on more than one string. The shape barres the E and A strings together at the fourth fret for the fifth and root, adds an individual finger on the C string's third fret for the suspended second, and lets the G string add a doubled fifth at the first fret.

A sus2 chord removes the third and replaces it with the second scale degree, leaving C#sus2 in the same harmonically open, undecided space every suspended-second chord occupies — neither bright nor dark until it resolves. It works as a quick, airy detour from plain C# major, popular in folk and singer-songwriter styles that like a moment of ambiguity before settling back onto the tonic. Respelled as Dbsus2, it shows up as a decorative substitute wherever a Db-major-leaning arrangement wants that same open color.

How to Practice It

Set the barre across the E and A strings at the fourth fret first, since it anchors two of the chord's three notes at once, then add the C string's third fret and the G string's first fret as two separate, lower reaches below the barre. It's an unusual hand shape — a barre sitting above two lower individual fingers rather than below them — so it's worth practicing as its own motion rather than assuming it behaves like the more familiar low-barre-plus-open shapes elsewhere on the instrument.

Common Progressions

  • C#sus2 - C#, resolving the open second into the plain triad
  • I(sus2) - IV - V - I in the key of C# (C#sus2 - F# - G# - C#)
  • Respelled Dbsus2 - Db, the identical motion in flat notation
  • vi - IV - I(sus2), landing on the unresolved color.

FAQ

Why does C#sus2 reach as high as the fourth fret?
None of its three notes happen to cluster near the nut on more than one string simultaneously, so the barre covering two of them lands at the fourth fret rather than lower.
How does C#sus2 resolve into C# major?
By releasing the barre and the C string's individual finger and reforming into C# major's own barre-plus-pinky-reach shape — a genuine change in hand position rather than a single small adjustment.
Is C#sus2 harder than Csus2?
Yes, generally — Csus2 keeps one string open and its barre lower on the neck, while C#sus2 needs every string fretted and its barre sits a full fret higher.
What's the enharmonic spelling for this chord?
Dbsus2 — the identical pitches, more commonly seen in ukulele arrangements adapted from flat-key charts.
Which note does C#sus2 remove, and which replaces it?
It drops the major third, F, and replaces it with the second scale degree, D#, the same substitution every sus2 chord makes relative to its parent major triad.
Can C#sus2 be strummed as a standalone color rather than a passing chord?
Yes, particularly in folk-leaning arrangements that favor its open, unresolved ambiguity as a texture worth holding rather than rushing past.
Why does the barre sit above the individual finger rather than below it here?
It comes down to where this particular chord's fifth and root happen to fall on the E and A strings versus where the second falls on the C string — an accident of GCEA tuning rather than any deliberate design choice.
Is C#sus2 a good chord to isolate before tackling C#sus4?
It's a reasonable warm-up, since both share the same general hand region, though the two chords use genuinely different finger combinations, so mastering one doesn't automatically transfer much technique to the other.
How many total notes does this C#sus2 voicing produce, counting the doubled fifth?
Four fretted contacts producing three distinct pitches — root, second, and a fifth doubled on two strings — which is typical of how a three-note chord gets spread across four available strings on this instrument.
Would this chord be usable in a purely instrumental ukulele arrangement, or mainly as accompaniment?
Both — its open, chiming quality works as a texture chord under a vocal line, but it's just as at home as a brief harmonic color inside a fingerpicked solo arrangement that lingers on individual chord tones.
