Jimmy Van Heusen · 1939 · G major · AABA, 32 bars
In the very first bar the tonic gives way to a whole ii–V moved up a half step, which then slips down onto the real ii chord: a side-slip, the most compact chromatic approach there is. The rest of the A section keeps that density, a new chord almost every two beats.

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.

The whole form, not just these bars: JamShed’s trio — double bass, drums and piano — plays it with you at the tempo and in the key you choose. Loop the bars that trip you up, mute the instrument you play, share the link.
Read in G major, the key of the tune. Taken on its own, with nothing around it, this excerpt is just as easy to hear in E 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 |
|---|---|---|---|---|
| G6 | I | Tonic | G6 is the tonic of G. It is where the progression is at rest. | High |
| Bbm7 | biii | Other | Bbm7 does not take a functional role in G. It sits on bIII and is best heard as colour, or as a sign that the tonal center has moved. | Low |
| Eb7 | subV7/V | Dominant | Eb7 is a tritone substitute — subV7/V. It carries the same tritone as A7, the real dominant of D, but resolves down a semitone instead of down a fifth. | Low |
| Am7 | ii | Predominant | Am7 is the ii chord of G: the classic predominant. It prepares the dominant and almost always moves to it. | High |
| B7 | V7/vi | Dominant | B7 is functioning as V7/vi: a secondary dominant. It is the dominant of E, not of the home key, so it borrows the pull of a V-I and points it at vi instead. | Medium |
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 →

Against a tonic of G major the passage numbers as I – biii – subV7/V – ii – V7/vi. Inside those 5 chords there is at least one secondary dominant and a tritone substitute. Strip it to two notes per chord, the third and the seventh, and play it under tempo. Eb7 gives you G and C#; 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.
Thirty-two bars, AABA, with a new chord almost every two beats in the A sections — the excerpt’s side-slipped ii–V, a slash chord descending in the bass, a minor ii–V to the relative minor and a chromatic return. The bridge moves to E♭ major, a key a major third away, and comes back through G minor. It rewards a slow tempo; at speed the harmony blurs.
Jimmy Van Heusen and Eddie DeLange wrote it for the 1939 Broadway show Swingin’ the Dream, a jazz version of A Midsummer Night’s Dream that closed within weeks. The song survived: Benny Goodman recorded it in 1940, and Miles Davis included it, with a vocal by Kenny Hagood, in the 1950 nonet sessions later issued as Birth of the Cool.
