G#9 chord
The G-sharp dominant ninth chord (abbreviated "G#9 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 dominant seventh chord.
In practice, the fifth (D♯) is sometimes omitted from the G#9 chord because it's not always possible to play all notes simultaneously.
