About G#add9
The G#add9 chord is made up of G# (root), B# (major third), D# (perfect fifth) and A# (ninth). Its interval formula is 1 – 3 – 5 – 9. The added ninth gives the major chord an open, modern color, widely used in pop and rock.
G#add9 has no standard open shape in the CAGED system, so its 25 voicings are sorted only by difficulty and position on the neck. Another way to write G#add9 is Abadd9 (the same piano key, with a different name). The usual choice is Abadd9.
