A7sus4

— About this chord

A7sus4 delivers a suspended, open, and anticipatory feel—edgy yet hopeful, with a bright but unresolved tension that begs to resolve to A7 or D. Ubiquitous in rock and pop ballads, tasty in blues turnarounds, and a staple color in jazz comping and folk strumming. Its modal, droning vibe can hint at Celtic or Americana flavors, especially with open-string voicings. Technically beginner-friendly on guitar (common open shapes) yet flexible for sophisticated jazz voicings on keys. Often used as a dominant-function suspended chord (A7sus, A sus4, Asus4(7)) to delay the third, create suspense, and set up a satisfying release.
