Wayne Shorter · 1966 · C minor · 12-bar minor blues in 6/4
A minor blues in six, played so that the metre keeps sliding. The harmony is the oldest form there is; everything modern about the tune happens in the rhythm section instead.

This is a short excerpt quoted for analysis, not the full chart, and this composition is very likely still in copyright. Published versions and recordings disagree with each other about the rest of the tune, and often about these bars too.
Every one of these tunes is assembled out of the same handful of harmonic resources. Jazz Harmony is those resources, explained in the order in which they build on each other.

Numbered against C minor, the excerpt is i – iv. Inside those 8 chords there is a chord borrowed from the parallel mode. There is no dominant to lean on, so the phrase is carried by whichever note refuses to settle. Sustain each chord long enough to hear which one that is before moving on. Blues for Alice, All Blues and So What use the same device, which is the argument for learning it once properly rather than three times by accident.
A minor blues in six, and the metre is the composition. The twelve-bar frame is intact underneath, but the bass figure divides each bar in a way that lets the rhythm section imply both a slow three and a fast two at once, so the pulse is genuinely ambiguous rather than merely syncopated. The harmony holds still for long stretches and then moves suddenly, and the famous performance takes liberties with the bar count that have never been standardised — which means the tune is one of the few where a working group has to agree in advance on what the form even is.
Wayne Shorter recorded it in 1966 on his own Adam’s Apple, but the version that fixed it in the repertoire came the same year on the Miles Davis Quintet’s Miles Smiles, where the rhythm section treats the metre as material to be reshaped rather than kept. That recording is why the tune is considered difficult; the composition on paper is not.
Open these chords in the analyzer and change them. Move one chord, substitute a dominant, take the ii away — the reading updates and tells you what you just did.
