G#m11 chord

The G-sharp minor eleventh chord (abbreviated G#m11 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-sharp minor ninth chord.

In practice, the fifth (D♯) is often omitted from the G#m11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
