C#7sus4 Chord on Guitar
C#7sus4 = C# – F# – G# – B (Root, Perfect 4th, Perfect 5th, Minor 7th)
C#7sus4 combines a dominant seventh's forward pull with a suspended fourth's unresolved tension, producing a chord strongly associated with gospel and church music, where a sus4 resolving into a dominant seventh is practically a signature move. At the ninth fret it's an E-shape barre, structurally close to the plain 7sus4 shape most guitarists first meet lower on the neck on a different root.
The notes are C#, F#, G#, and B — root, fourth, fifth, flat seventh — with no third present at all, meaning the chord carries dominant harmonic function through the flat seventh without committing to major or minor color the way a plain C#7 would. That combination — dominant pull plus suspended ambiguity — is exactly the sound behind the classic 'amen' cadence heard throughout gospel music, and it's found its way into rock and pop as a way to add tension right before a resolution.

How to Practice It
Because the third is dropped entirely, this shape is actually simpler to finger than a full C#7 despite the more complex-sounding name — fewer independently fretted notes means less coordination even at this high fret position. It's worth practicing the classic 7sus4-to-7 resolution, sliding the fourth down to the third, the same way sus4-to-major gets practiced on plain triads, since that specific move is what gives this chord its recognizable gospel-cadence character.
Common Progressions
- C#7sus4 – C#7 – F# (a classic gospel-style suspension resolving into the tonic)
- F# – C#7sus4 – C#7 – F# (IV – V7sus4 – V7 – I, a church-cadence pattern)
- C#7sus4 – F# (V7sus4 – I, skipping the fully resolved dominant)
- G# – C#7sus4 – F# (a rock-style cadence using suspended dominant color)
FAQ
- Why is C#7sus4 so associated with gospel music?
- The classic 'amen' cadence heard at the end of many hymns is built on exactly this move — a suspended dominant seventh resolving into its full form or straight into the tonic.
- How does C#7sus4 differ from plain C#7?
- C#7 includes the major third, giving it a clear major-dominant color, while C#7sus4 replaces that third with a fourth, leaving a more ambiguous, suspended sound that still carries dominant pull.
- Is C#7sus4 easier to finger than C#7?
- Yes, generally — with the third dropped, 7sus4 chords are frequently simpler to finger than their fully-resolved dominant seventh counterparts.
- What's the classic resolution move for C#7sus4?
- Sliding the fourth down a half step to the third turns C#7sus4 into plain C#7, mirroring the sus4-to-major resolution on plain triads but landing on a dominant seventh instead.
- Does C#7sus4 ever skip straight to the tonic without resolving to C#7 first?
- Yes — plenty of progressions move directly from the suspended dominant to its tonic, using the sus4's own tension as enough of a pull without needing the intermediate step.
- Is C#7sus4 common outside gospel and church music?
- Yes — rock and pop rhythm guitar borrow the sound regularly, especially in anthemic choruses that want a big, suspended buildup right before a resolving chord.
- Does the missing third make C#7sus4 harder to identify by ear than C#7?
- A little, at first — without a clear major or minor third, new listeners sometimes struggle to place the chord's quality, but once the flat seventh's pull is recognized, the suspended sound becomes just as identifiable as any resolved dominant.
