Short answer

Added ninth chords are open and shimmering. Unlike a ninth chord they leave the seventh out, so the added second degree colours the triad without any of the tension a dominant brings, a favourite of pop and worship guitarists.

How to use the G♯add9 chord

The G♯add9 chord is built from a root, a major third, a perfect fifth and a major ninth. Start at the root G♯ and stack the intervals to get the whole chord: G♯, B♯, D♯ and A♯. The same formula gives you the chord in any other key.

Added ninth chords replace plain major chords when a part needs air, especially in fingerpicked guitar and piano pads. They are everywhere in pop ballads, worship music and indie rock.

How G♯add9 differs from similar chords

G♯add9 adds a ninth to G♯ and leaves the seventh out, which is exactly what separates it from G♯9 and G♯maj9. Unlike G♯sus2, it keeps the major third, so it stays clearly major. The ninth is the same note as the second, only an octave higher.

Where G♯add9 is used

No progression is shown for this spelling

Every key G♯add9 would have a function in has a tonic that needs a double accidental, which is not a key this library teaches. The enharmonic spelling carries the same chord in a key that exists.
