Antônio Carlos Jobim · 1963 · D minor · 32 bars
The bass walks down by half steps — D, C♯, C, B, B♭ — and each step gets a different kind of chord. The melody barely moves; the descending line underneath does all the expressive work.

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 D minor, the key of the tune. Taken on its own, with nothing around it, this excerpt is just as easy to hear in B♭ 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 |
|---|---|---|---|---|
| Dm | i | Tonic | Dm is the tonic of Dm. It is where the progression is at rest. | High |
| C#dim7 | vii° | Dominant | C#dim7 is the diminished seventh on the leading tone of Dm: the dominant with its root replaced by a b9. | High |
| Cm6 | bvii | Other | Cm6 does not take a functional role in Dm. It sits on bVII and is best heard as colour, or as a sign that the tonal center has moved. | Low |
| G7/B | V7/bVII | Dominant | G7/B is functioning as V7/bVII: a secondary dominant. It is the dominant of C, not of the home key, so it borrows the pull of a V-I and points it at bVII instead. Also readable as IV7. | Low |
| Bbmaj7 | bVI | Predominant | Bbmaj7 is bVI of Dm, a predominant on the sixth degree of natural minor. | High |
| Ebmaj7 | bII | Other | Ebmaj7 does not take a functional role in Dm. It sits on bII and is best heard as colour, or as a sign that the tonal center has moved. | Low |
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 →

Numbered against D minor, the excerpt is i – vii° – bvii – V7/bVII – bVI – bII. Inside those 6 chords there is at least one secondary dominant. Take the roots away and keep the third and seventh. In G7/B that is B and F. Those two notes decide where the progression is going, and hearing them move is worth more than naming the chords. Now’s the Time, Billie’s Bounce and Straight, No Chaser use the same device, which is the argument for learning it once properly rather than three times by accident.
Thirty-two bars, with each chord held for two bars over most of the form. The first half is the excerpt’s descending bass; the second half reaches B♭ again by a different route and closes with a chromatic ii–V into D minor. The harmony moves so slowly that the melody, which barely moves at all, can sit on the same notes while their meaning changes underneath.
Jobim wrote it with Vinícius de Moraes (“Insensatez”); its harmony is often compared with Chopin’s Prelude in E minor, Op. 28 No. 4, which also sets a nearly static melody over a slowly descending chromatic bass. Frank Sinatra recorded it with Jobim in 1967, and it has been part of the bossa repertoire of jazz players ever since.
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.
