E9 chord
The E dominant ninth chord (abbreviated "E9 chord") is a five-note chord consisting of the notes E, G♯, B, D, and F♯. The chord is formed by adding a major ninth to a E dominant seventh chord.
In practice, the fifth (B) is sometimes omitted from the E9 chord because it's not always possible to play all notes simultaneously.
