Fbmaj9 chord

The F-flat major ninth chord (abbreviated Fbmaj9 chord) is a five-note chord consisting of the notes F♭, A♭, C♭, E♭, and G♭. The chord is formed by adding a major ninth to the F-flat major seventh chord.

In practice, the fifth (C♭) is sometimes omitted from the Fbmaj9 chord because it's not always possible to play all notes simultaneously.
