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