G#maj11 chord

The G-sharp major eleventh chord (abbreviated G#maj11 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 major ninth chord.

In practice, the fifth (D♯) is often omitted from the G#maj11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
