Understanding Dominant Ninth Chords
Dominant ninth chords are extended chords that add a ninth to a dominant seventh chord. The "ninth" is typically a major ninth, meaning it is an octave plus a major second above the root. The inclusion of the minor seventh (E♭ in the F9 chord) gives it its "dominant" quality, creating a strong harmonic pull towards a tonic chord in a musical progression.
