D#13

— About this chord

D#13 (Eb13) stacks the dominant 7th with a rich 13th on top for a full, horn-section-like jazz and blues color. Its gritty pull toward G# major or minor makes it a favorite turnaround chord in blues shuffles and funk vamps, and a staple extended dominant in jazz comping where the 13th brightens the b7 without losing tension. On guitar it favors a compact A-shape grip with the root on the 5th string; on keys it invites lush left-hand rootless voicings. Also searched as Eb13, D#dom13, D-sharp thirteenth.
