The Minor ii-V-i · Jazz Wiki

The minor ii-V-i is what happens when you take jazz’s most common cadence — The ii-V-I Progression — and run it through the darker gravity of a minor key. Every chord gets heavier: the ii turns half-diminished, the V picks up a bruised ♭9, and the i resolves to a minor chord that can’t quite decide between a major or minor seventh. This is the sound behind noir-tinged standards like Blue Bossa — melancholy but still propulsive, because the dominant still pulls hard toward home.

Why Minor Keys Darken Every Chord

In Minor Key Harmony, the notes available above the tonic sit differently than they do in major, and that reshapes the whole cadence. The ii chord, built on the 2nd scale degree, stacks a diminished 5th instead of a perfect one, turning a plain m7 into a Half-Diminished Chord — jazz players write this as m7♭5 or iiø7. The V chord keeps its dominant quality (you still need a strong leading tone for the cadence to pull hard), but the borrowed ♭6 of the minor scale lands as a ♭9 above the dominant root, giving it a bite the major-key V7 never has. The result is the same underlying job — Functional Harmony pulling you home — done with sharper edges at every step.

Built From the Harmonic Minor Scale

Every note in the minor ii-V-i traces back to one scale: The Harmonic Minor Scale. C harmonic minor is C–D–E♭–F–G–A♭–B–C, and its raised 7th (B natural) is exactly the leading tone that gives the V7 its pull toward C. Stack chords on the 2nd and 5th degrees of that scale and the ii and V appear automatically, no extra theory required — the ii is half-diminished because D-F-A♭-C is what you get when you build a seventh chord on scale degree 2, and the V is an altered dominant because G-B-D-F stacked with the scale’s A♭ gives you a ♭9 for free.

ii chord = built on scale degree 2 of harmonic minor (the flatted 5th comes straight from the scale)
V chord = built on scale degree 5, using the raised 7th of harmonic minor as its 3rd and the ♭6 as its ♭9
i chord = the tonic triad, colored by whether you borrow the ♮6 or ♮7 from The Melodic Minor Scale or leave it as plain natural minor

Spelling It Out in Three Keys

C minor: Dø7 (D–F–A♭–C) → G7♭9 (G–B–D–F–A♭) → Cm6 (C–E♭–G–A) or Cm(maj7) (C–E♭–G–B)
D minor: Eø7 (E–G–B♭–D) → A7♭9 (A–C♯–E–G–B♭) → Dm6 (D–F–A–B) or Dm(maj7) (D–F–A–C♯)
G minor: Aø7 (A–C–E♭–G) → D7♭9 (D–F♯–A–C–E♭) → Gm6 (G–B♭–D–E) or Gm(maj7) (G–B♭–D–F♯)

Notice the ♭9 on each V chord (A♭, B♭, E♭ respectively) — that single note is doing the most work to signal “minor” rather than major, and it’s the same note that would be the ♭6 if you harmonized The Natural Minor Scale instead of the harmonic form.

Here is the same ii-V-i (using the m6 tonic) written out as block chords in all three keys:

Scale Choices and the Flexible Tonic

Over the ii, most players reach for Locrian Natural 2 rather than a plain Locrian mode, because raising the 2nd degree turns the scale’s half-step rub against the root into a usable natural 9 — the chord’s Guide Tones (the 3rd and 7th that define its sound) stay put either way. Over the altered V7, The Altered Scale or Phrygian Dominant Scale both work depending on how much extra tension you want beyond the basic ♭9 — the altered scale adds ♯9 and ♭13 for maximum bite, while Phrygian dominant keeps a natural 5th for a more grounded, Spanish-tinged color. On the tonic, jazz players treat m6, m(maj7), and plain m7 as genuinely interchangeable in practice; Sixth Chords and the Minor-Major Seventh Chord both borrow from melodic minor, so which one you land on is really a Voice Leading choice in the moment, not a fixed rule.

♫ Listen

Joe Henderson & Kenny Dorham — “Blue Bossa” (Page One, 1963): the head states Dø7–G7♭9–Cm with total clarity in the first 20 seconds; McCoy Tyner’s comping makes the half-diminished-to-altered motion easy to hear before Henderson’s tenor solo even starts.
Bill Evans Trio — “Autumn Leaves” (Portrait in Jazz, 1959): listen around 1:15–1:45 for Evans’ rootless voicings under the G-minor turnaround, with Scott LaFaro’s bass reinforcing the ii-V-i motion in real time.
Chet Baker & Bill Evans — “Alone Together” (Chet, 1958/59): a slow ballad in D minor built almost entirely on minor ii-V-i motion; listen to the first melody chorus for the progression’s lyrical, unhurried side.
