C7sus4
4-note dominant 7th suspended 4th on C — C, F, G, A♯.
Press to hear the chord strummed low to high.
A dominant seventh with the fourth in place of the third — the suspension keeps the pull without committing to major or minor.

Interval formula
| Degree | Note | What it is |
|---|---|---|
| 1 | C | root |
| 11 | F | eleventh (perfect fourth) |
| 5 | G | perfect fifth |
| ♭7 | A♯ | flat seventh (dominant) |
The formula reads in semitones above the root (C): 1, 11, 5, ♭7. A voicing may leave a tone out — often the fifth — but never adds one from outside this set.

Read a diagram top-down: the thick bar is the nut, dots are where to press (the number is which finger), means play the open string, means don't play it. A bar across strings is a barre.
