D9 Piano Chord
D9 is a dominant 9th chord rooted on D. A dominant 7th with the ninth stacked on top. Funk lives here — this is the shape under a thousand James Brown vamps.
The notes
5 notes. The voicings below rearrange them — and one of them leaves the root out entirely.
How to play it
The ways this chord is actually played — it reaches past an octave, so the textbook inversions would stretch beyond one hand. Numbers next to each note are right-hand fingers — 1 is the thumb. Tap a key to hear it, or play the whole chord.
The notes in order, with the ninth up where it belongs. Wide — many players spread this across both hands.
The ninth folded down inside the octave, so the whole chord sits under one hand. Tighter and more modern sounding.
Drop the root and the chord still sounds like itself — the bass or your other hand covers it. This is what jazz pianists actually play.
Which voicing should you use?
Depends who else is playing. On your own, root position keeps the chord anchored. With a bass player or a left hand covering the root, the rootless voicing frees your right hand and stops the low notes turning to mud. The close voicing is the one to reach for when you want the colour without the width.
