The B-flat major thirteenth chord (abbreviated Bbmaj13 chord) is a seven-note chord consisting of the notes B, D, F, A, C, E, and G. The chord is formed by adding a thirteenth to the B-flat major eleventh chord.

In practice, the fifth (F) and eleventh (E) are often omitted from the Bbmaj13 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
