F13 chord
The F dominant thirteenth chord (abbreviated "F13 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 dominant eleventh chord.
In practice, the fifth (C) and eleventh (B♭) are often omitted from the F13 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
