D#add9 Guitar Chord Chart and Fingering
A D#add9 chord, also called D# add nine, is made of D#, F##, A# and E#. The ninth (E#) is the same pitch as the second, one octave higher, and unlike a sus2 chord the add9 keeps the major third.
All of its notes fall inside the D# major scale, which makes that scale a natural source of melody notes over the chord. Without a seventh, the chord stays a major triad with one added note. On the guitar this is the same chord as Ebadd9, which is written Eb, G, Bb and F. Because F## and E# appear in the D# spelling, Ebadd9 is the name you will normally see.
D# added 9th guitar chord is also written as D#add9, D#(add9), D#add2 or D#maj(add9).
