The G-sharp major ninth chord (abbreviated "G#maj9 chord") is a five-note chord consisting of the notes G, B, D, F, and A. The chord is formed by adding a major ninth to a G-sharp major seventh chord.

In practice, the fifth (D) is sometimes omitted from the G#maj9 chord because it's not always possible to play all notes simultaneously.
