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