Gbmaj9 chord
The G-flat major ninth chord (abbreviated "Gbmaj9 chord") is a five-note chord consisting of the notes G♭, B♭, D♭, F, and A♭. The chord is formed by adding a major ninth to a G-flat major seventh chord.
In practice, the fifth (D♭) is sometimes omitted from the Gbmaj9 chord because it's not always possible to play all notes simultaneously.
