D#7sus4

— About this chord

D#7sus4 (Eb7sus4) has a tense, suspended push—bright yet unresolved, with a bold, questioning mood that feels edgy and anticipatory. A staple in jazz turnarounds and blues vamps, it also fits pop and rock hooks where a chorus lift or pre-chorus build is needed. Its suspended fourth evokes gospel and R&B colors, with hints of Afro‑American church traditions and funk-inflected grooves. Technically it often uses barre or partial barre shapes; pianists voice it with clustered 4–b7–1–5 for a modern, sophisticated sound. Commonly used as a dominant-function chord that delays the third, it creates tension that resolves to D#7/Eb7 or to the tonic for a satisfying release.
