F7(#9) chord
The F dominant seventh sharp ninth chord (abbreviated "F7(#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 dominant seventh chord.
In practice, the fifth (C) is often omitted from the F7(#9) chord because it's not always possible to play all notes simultaneously.
