F#13 chord
The F-sharp dominant thirteenth chord (abbreviated "F#13 chord") is a seven-note chord consisting of the notes F♯, A♯, C♯, E, G♯, B, and D♯. The chord is formed by adding a thirteenth to a F-sharp dominant eleventh chord.
In practice, the fifth (C♯) and eleventh (B) are often omitted from the F#13 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
