Db7(#9) chord
The D-flat dominant seventh sharp ninth chord (abbreviated "Db7(#9) chord") is a five-note chord consisting of the notes D♭, F, A♭, C♭, and E. The chord is formed by adding an augmented ninth to a D-flat dominant seventh chord.
In practice, the fifth (A♭) is often omitted from the Db7(#9) chord because it's not always possible to play all notes simultaneously.
