C7sus4

About this chord

C7sus4 (C F G Bb), aka C dominant sus or C7sus, has a bold, suspended, questioning mood—open, gritty, and slightly tense before release. Staple in jazz, blues, funk, rock, and pop, it delivers that punchy vamp color heard in turnarounds and groove-based hooks. Hints of gospel and New Orleans R&B roots give it a soulful, Americana flavor, while its suspended fourth can suggest modal or Afro-Cuban funk feels. Technically beginner-friendly on guitar via common barre or open-shape grips, and a go-to piano voicing with stacked fourths for a modern bite. Often used as a dominant-function chord that delays the third, it creates tension that resolves satisfyingly to C7 or F.
