Theory behind the chord

Dominant ninth chords extend the dominant seventh with a ninth on top. They keep the pull of a seventh chord but sound fuller and more coloured, which is why funk and soul rhythm parts lean on them. On G#9 this structure sits on the root G#, so the degrees 1 – 3 – 5 – ♭7 – 9 map onto G#, C, D#, F# and A#.
