Dominant 9th sus4 Chords on Piano

The dominant 9th sus4 chord extends the 7sus4 by adding the 9th, creating a lush, open voicing with no third. The absence of the third leaves the chord ambiguous between major and minor, while the 9th adds color. It is a favorite in funk, neo-soul, and modern gospel for its rich, floating quality.
