G♭m9 Chord: Guitar, Piano and Notes
The G♭m9 chord is a minor ninth chord built on the root note G♭. Its notes are G♭, B𝄫, D♭, F♭ and A♭. It's enharmonically the same chord as F♯m9.
Minor ninth chords are smooth, cool and slightly melancholy. The ninth widens a minor seventh into something more spacious, which is why it anchors so much modern R&B, house and jazz comping.

How to use the G♭m9 chord
The G♭m9 chord is built from a root, a minor third, a perfect fifth, a minor seventh and a major ninth. Start at the root G♭ and stack the intervals to get the whole chord: G♭, B𝄫, D♭, F♭ and A♭. The same formula gives you the chord in any other key.
Minor ninth chords stand in for minor sevenths as the ii chord in a ii-V-I, or as the tonic of a minor groove. Neo-soul, house, jazz and R&B use them as the default minor colour.
How G♭m9 differs from similar chords
G♭m9 adds a major ninth to G♭m7, which sets it apart from a minor triad with only an added ninth and from G♭9, which has a major third. Its upper four notes form the major seventh chord a minor third above the root.
