Gm11 chord

The G minor eleventh chord (abbreviated Gm11 chord) is a six-note chord consisting of the notes G, B♭, D, F, A, and C. The chord is formed by adding an eleventh to the G minor ninth chord.

In practice, the fifth (D) is often omitted from the Gm11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
