Ray Noble · 1938 · B♭ major · AABA, 64 bars
The A section is calm; the bridge is the reason players are afraid of it. It walks ii-V-I through four keys a semitone apart at a tempo that leaves no time to think, which is why it became the bebop proving ground.

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 Bb major, the key of the tune. Taken on its own, with nothing around it, this excerpt is just as easy to hear in Eb 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.
| Chord | Roman numeral | Function | What it is doing | Confidence |
|---|---|---|---|---|
| Bbmaj7 | I | Tonic | Bbmaj7 is the tonic of Bb. It is where the progression is at rest. | High |
| Bbmaj7 | I | Tonic | Bbmaj7 is the tonic of Bb. It is where the progression is at rest. | High |
| Fm7 | ii/IV | Predominant | Fm7 is the ii of a secondary ii-V. Together with Bb7 it prepares Eb, so the pair tonicizes IV without leaving the key. | High |
| Bb7 | I7 | Tonic | Bb7 is the tonic, but built as a dominant seventh — the sound that defines the blues. The tonic keeps a b7 and stays at home anyway. Also readable as V7/IV. | Medium |
| Ebmaj7 | IV | Predominant | Ebmaj7 is the IV chord of Bb: subdominant. It moves away from the tonic without creating the pull of a dominant. | High |
A complete ii-V-I in Eb. Predominant, dominant, tonic: the sentence jazz harmony is built out of.
High, medium and low next to each numeral are judgements about musical context, not probabilities. A low rating marks a bar that can honestly be read more than one way. How the ratings are decided →
In Bb major the excerpt reads I – ii/IV – I7 – IV. Inside those 5 chords there is a complete ii-V-I. Play it slowly with only two voices — the third and seventh of each chord. In Bb7 those are D and Ab, and watching where that pair goes next tells you more about the progression than the root movement does. The same device turns up in Autumn Leaves, All The Things You Are and Tune Up, in other keys and at other tempos.
Sixty-four bars rather than thirty-two, which doubles everything and is the first thing to know before calling it. The A sections stay close to home and are not the difficulty. The bridge is: it steps up to B major, a key with almost nothing in common with the B♭ the tune lives in, then descends through a series of ii-V cadences a whole tone apart until it arrives back at the dominant. At the tempos this tune attracts, that bridge is sixteen bars of unfamiliar keys arriving faster than most players can name them, and it is the reason Cherokee is treated as a rite of passage rather than a standard.
Ray Noble, an English bandleader, wrote it in 1938 as part of an orchestral suite, and it became a swing-era hit for Charlie Barnet. Its place in jazz history comes from Charlie Parker, who described working on it in a Harlem chili house in 1939 and finding that building lines from the upper intervals of the chords let him play what he had been hearing. Parker’s “Ko-Ko”, recorded in 1945, is a contrafact on this form and takes the bridge at a tempo that made the point permanently.
Take these bars into the analyzer and interfere with them. The fastest way to learn what a chord was doing is to remove it and read what the analysis says instead.
