E#m9 chord

The E-sharp minor ninth chord (abbreviated E#m9 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 the E-sharp minor seventh chord.

In practice, the fifth (B♯) is sometimes omitted from the E#m9 chord because it's not always possible to play all notes simultaneously.
