D#7#9

— About this chord

D#7#9 (Eb7#9), the famous 'Hendrix chord,' clashes a minor-3rd-sounding #9 against the major 3rd for a gritty, funky, blues-rock crunch. It is the signature sound of psychedelic funk and blues-rock riffing, adding swagger to dominant vamps without resolving cleanly — perfect for held tension in a riff or outro chord. On guitar it's a tight, muted-bass grip; on keys it's often voiced as a rootless cluster. Also searched as Eb7#9, D#dom7#9, Hendrix chord.
