About F#add9
The notes of F#add9 are F# (root), A# (major third), C# (perfect fifth) and G# (ninth). In scale degrees above the root, the formula is 1 – 3 – 5 – 9. It is an added-ninth chord: the major chord plus the ninth (the second, an octave higher) with no seventh, and it sounds wide and bright.
F#add9 has no standard open shape in the CAGED system, so its 17 voicings are sorted only by difficulty and position on the neck. Another way to write F#add9 is Gbadd9 (the same piano key, with a different name). F#add9 is the usual choice.
