Cbmaj9 chord
The C-flat major ninth chord (abbreviated "Cbmaj9 chord") is a five-note chord consisting of the notes C♭, E♭, G♭, B♭, and D♭. The chord is formed by adding a major ninth to a C-flat major seventh chord.
In practice, the fifth (G♭) is sometimes omitted from the Cbmaj9 chord because it's not always possible to play all notes simultaneously.
