G#7(#9) chord
The G-sharp dominant seventh sharp ninth chord (abbreviated "G#7(#9) chord") is a five-note chord consisting of the notes G♯, B♯, D♯, F♯, and A. The chord is formed by adding an augmented ninth to a G-sharp dominant seventh chord.
In practice, the fifth (D♯) is often omitted from the G#7(#9) chord because it's not always possible to play all notes simultaneously.
