How pianists voice Gm7

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

G1F♭7B♭♭3

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

D5F♭7A9B♭♭3

♭3 · 5 · ♭7 · 9 — no root: the bass player has it. The left-hand voicing of modern jazz piano. Without G underneath, the same keys read as B♭maj7 — the bass turns them into Gm7.

Rootless B From the 7th

F♭7A9D5B♭♭3

♭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

D5G1F♭7B♭♭3

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

Gm7 inversions

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

Root position Gm7

G1D5F♭7B♭♭3

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

1st inversion Gm7/B♭

D5F♭7G1B♭♭3

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

2nd inversion Gm7/D

D5F♭7G1B♭♭3

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

3rd inversion Gm7/F

F♭7G1D5B♭♭3

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