D# Dominant Ninth Sharp Eleventh Added Guitar Chord Fingering

Take a dominant seventh on D#, add the ninth and the sharp eleventh, and you have D#9(#11) (D# ninth sharp eleven): D#, F##, A#, C#, E# and G##.

The major third F## and the minor seventh C# sit a tritone apart, and that pair gives the chord its dominant pull. Open Eb9(#11) to see the same sound spelled with flats. Over it the D# Lydian Dominant scale works well, since it holds all six chord tones plus a sixth.

The sharp eleventh G## is a tritone above the root, so the chord points toward a resolution a fourth higher.

D# 9th with sharp 11th guitar chord is also written as D#9(#11), D#9#11 or D#9+11.
