G7(#9) chord
The G dominant seventh sharp ninth chord (abbreviated "G7(#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 dominant seventh chord.
In practice, the fifth (D) is often omitted from the G7(#9) chord because it's not always possible to play all notes simultaneously.
