Fbm9 chord
The F-flat minor ninth chord (abbreviated "Fbm9 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 a F-flat minor seventh chord.
In practice, the fifth (C♭) is sometimes omitted from the Fbm9 chord because it's not always possible to play all notes simultaneously.
