Well, You Needn’t — Chord Progression & Harmonic Analysis

Two chords a semitone apart, alternating, for the whole A section. Neither resolves to the other and neither is a passing chord — Monk simply put a tritone substitute next to its own target and left them there.

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.

Read in F major, the key of the tune. Taken on its own, with nothing around it, this excerpt is just as easy to hear in Bb major — a few bars are often not enough to fix a tonic, and that ambiguity is a real property of the music rather than a gap in the analysis.

Why this example matters

Against a tonic of F major the passage numbers as I7 – subV7. Inside those 8 chords there is a tritone substitute. Strip it to two notes per chord, the third and the seventh, and play it under tempo. F7 gives you A and Eb; follow that pair from chord to chord and the voice leading becomes audible in a way the root motion never makes it. Once you can hear it here, it is hard to miss in Blues for Alice, All Blues and So What.

How the rest of Well, You Needn’t goes

The A sections alternate between the tonic and a chord a semitone above it, shifting back and forth without either one being prepared — parallel motion rather than functional harmony. The bridge is more famous still: a series of dominant chords moving in parallel up and then back down by semitone, which resolves nothing and is meant to resolve nothing. There is a well-known discrepancy between the published chart and what its composer actually played, so the bridge exists in two circulating versions.

Well, You Needn’t on record

Monk wrote it in 1944 and recorded it repeatedly. Miles Davis recorded it in 1954 at the session where he and Monk reportedly disagreed about accompaniment, an incident that has been retold so often it has become part of the tune’s biography. The parallel bridge is one of the clearest early examples of harmony used as sound rather than as function.
