The G-flat major thirteenth chord (abbreviated Gbmaj13 chord) is a seven-note chord consisting of the notes G, B, D, F, A, C, and E. The chord is formed by adding a thirteenth to the G-flat major eleventh chord.

In practice, the fifth (D) and eleventh (C) are often omitted from the Gbmaj13 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
