G9 chord
The G dominant ninth chord (abbreviated "G9 chord") is a five-note chord consisting of the notes G, B, D, F, and A. The chord is formed by adding a major ninth to a G dominant seventh chord.
In practice, the fifth (D) is sometimes omitted from the G9 chord because it's not always possible to play all notes simultaneously.
