How to play
Every ukulele shape for B9 needs a barre, and the lowest one starts at fret 2. Keep the index finger straight and as close to the fret wire as possible, and let the wrist rather than the thumb supply the pressure.
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 B9 this structure sits on the root B, so the degrees 1 – 3 – 5 – ♭7 – 9 map onto B, D#, F#, A and C#.
