Hoagy Carmichael · 1938 · F major · AABA, 32 bars
A ii-V walks the tonic up to IV in two bars, and then IV is turned minor. The borrowed chord lands on the bar you have just been taught to hear as home, which is why the move stings rather than merely colours.

Bar 4 is the borrowed minor iv. Charts also print B♭dim7 there — same function, same voice-leading — and bar 4 is a well-known reharmonisation point.
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 minor — 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 |
|---|---|---|---|---|
| Fmaj7 | I | Tonic | Fmaj7 is the tonic of F. It is where the progression is at rest. | High |
| Cm7 | ii/IV | Predominant | Cm7 is the ii of a secondary ii-V. Together with F7 it prepares Bb, so the pair tonicizes IV without leaving the key. | High |
| F7 | I7 | Tonic | F7 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 |
| Bbmaj7 | IV | Predominant | Bbmaj7 is the IV chord of F: subdominant. It moves away from the tonic without creating the pull of a dominant. | High |
| Bbm6 | iv | Predominant | Bbm6 is a minor iv in a major key, borrowed from the parallel minor. Its b6 pulls down into the third of the tonic — one of the most recognisable sounds in the repertoire. | Medium |
A complete ii-V-I in Bb. 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 →
Read in F major, these bars come out as I – ii/IV – I7 – IV – iv. Inside those 5 chords there is a complete ii-V-I and a chord borrowed from the parallel mode. The shortest way in is a two-voice reduction: third and seventh only, slowly. F7 contributes A and Eb, and where that pair resolves is the whole story of the passage. You will meet the same move again in Blues for Alice, All Blues and So What, transposed and at a different pace.
A ballad that stays close to home for most of its length and gets its colour almost entirely from borrowed chords rather than from modulation — minor-quality harmony appearing inside a major key, used to darken a phrase without moving anywhere. The melody sits low and uses long values, so the piece is often chosen as a first ballad for a singer. For an instrumentalist the difficulty is the opposite of the usual one: there is very little happening, and the tune will expose a thin sound instantly.
Hoagy Carmichael wrote the music in 1938 and Ned Washington the lyric. Glenn Miller had the first hit with it, but the readings that matter to jazz players came later — Sarah Vaughan’s, and Norah Jones’s much later still, which reintroduced it to a general audience. It is one of the few standards whose jazz reputation rests more on singers than on instrumentalists.
