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.
