Root position

The ii chord of a minor key: Eø7 → A7(♭9)Dm is the minor ii–V–i in D minor. It is also the vii chord of F major, and it has the same notes as Gm6.

How pianists voice Eø7

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

E1G♭3D♭7

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

G♭3D♭7B♭♭5F♯9

♭3 · ♭5 · ♭7 · 9 — no root: the bass player has it. The left-hand voicing of modern jazz piano. Without E underneath, the same keys read as Gm(maj7) — the bass turns them into Eø7.

Rootless B From the 7th

D♭7G♭3F♯9B♭♭5

♭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

E1G♭3D♭7B♭♭5

♭5 · 1 · ♭3 · ♭7 — close position with the second voice from the top dropped an octave: wider, warmer, the standard for chord melody.

Eø7 inversions

The same 4 notes with a different one in the bass. Each inversion is written as a slash chord.

Root position Eø7

E1G♭3D♭7B♭♭5

Root at the bottom, stacked in 3rds: 1 · ♭3 · ♭5 · ♭7.

1st inversion Eø7/G

G♭3D♭7E1B♭♭5

G (the ♭3) in the bass: ♭3 · ♭5 · ♭7 · 1.

2nd inversion Eø7/B♭

D♭7E1G♭3B♭♭5

B♭ (the ♭5) in the bass: ♭5 · ♭7 · 1 · ♭3.

3rd inversion Eø7/D

D♭7E1G♭3B♭♭5

D (the ♭7) in the bass: ♭7 · 1 · ♭3 · ♭5.
