G#add9 Guitar Chord Chart and Fingering
The G# add nine chord, written G#add9, stacks root G#, major third B#, fifth D# and ninth A#. Because there is no seventh, add9 is not a dominant ninth or a major ninth: it keeps the major triad and adds a single note.
Over this chord, the G# major scale is a safe source of notes, as it includes every one of its tones. The distance from the root to the ninth is fourteen semitones, a major second plus an octave. Its twin, Abadd9, spells the same chord Ab, C, Eb and Bb and needs fewer accidentals. Spelling it as G#add9 needs B#, so Abadd9 is the version you will normally see.
G# added 9th guitar chord is also written as G#add9, G#(add9), G#add2 or G#maj(add9).
