Cadenzaminor ii–V–i · E♭ minor
Fø7 – B♭7(♭9) – E♭m6
The minor ii–V–i: Fø7 (half-diminished), B♭7(♭9) and E♭m6 in E♭ minor. The flattened 9th on the V is the sound of a minor key arriving home — “Autumn Leaves” has this one too, every time it turns to the relative minor.
Shells — the left hand
Root, 3rd and 7th: the three notes that say what a chord is. Every jazz pianist learns these first.

Rootless voicings — the ones on the records
No root at all — the bass player has it — and the colour notes added instead. Watch how little the hand moves.

Why it works
The ♭5 of Fø7 is the same note as the ♭9 of B♭7(♭9), and it falls to the 5th of E♭m6; the ♭7s slide to the 3rds exactly as in major. The tonic is written as a minor 6th here — the m7 or m(maj7) are just as common, and the ear accepts all three.
