Short answer

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.

Where G♭m9 is used

No progression is shown for this spelling

Every key G♭m9 would have a function in has a tonic that needs a double accidental, which is not a key this library teaches. The enharmonic spelling carries the same chord in a key that exists.
