How pianists voice Dmaj9(♯11)
Nobody plays a jazz chord in root position. These are the shapes that actually get played — the same ones Cadenza shows when you play the chord.
Shell Left hand
1 · 3 · 7 — root, 3rd and 7th: the three notes that say what the chord is. Left hand, low; everything else is colour.
Rootless A From the 3rd
3 · 5 · 7 · 9 — no root: the bass player has it. The left-hand voicing of modern jazz piano. Without D underneath, the same keys read as F♯m7 — the bass turns them into Dmaj9(♯11).
Rootless B From the 7th
7 · 9 · 3 · 5 — the other half of the pair. A and B alternate through a ii–V–I so the hand barely moves.
Drop 2 Two hands
5 · 1 · 3 · 7 — close position with the second voice from the top dropped an octave: wider, warmer, the standard for chord melody.
