D#6/9

— About this chord

D#6/9 (Eb6/9) blends the sweetness of the major 6th with the shimmer of the added 9th for a lush, unresolved-sounding tonic color loved in bossa nova and jazz comping. It works beautifully as a soft, floating tonic chord that never needs to resolve, giving progressions an airy, sophisticated close. On guitar it's a compact 5-string grip movable across the neck; on piano it's a favorite closing voicing for ballads. Also searched as Eb6/9, D#6add9, D-sharp six-nine.
