F#maj9 chord

The F-sharp major ninth chord (abbreviated F#maj9 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 the F-sharp major seventh chord.

In practice, the fifth (C♯) is sometimes omitted from the F#maj9 chord because it's not always possible to play all notes simultaneously.
