faq:
  - q: What is a ii V I progression?
    a: It is the sequence from the supertonic chord through the dominant to the tonic: in C major, D minor to G (usually G7) to C. The roots fall by fifths while the tritone in the dominant resolves by semitone, making it the strongest short progression in tonal music.
  - q: Why is ii V I so common in jazz?
    a: It cycles the fundamental predominant-dominant-tonic motion into a compact loop that fits turnarounds, song endings, and modulation. Jazz players have also built an extensive substitution vocabulary on it, so one progression supports endless reharmonization.
  - q: How does ii V I work in a minor key?
    a: The supertonic becomes half-diminished (iiø7), the dominant stays major or becomes a V7 with alterations, and the tonic is minor with a raised leading tone in the dominant chord. In A minor: Bø7 to E7 to Am.
  - q: What is a ii V I turnaround?
    a: A turnaround is a ii V I (often extended with a VI chord) placed at the end of a section to cycle back to the top. It refreshes the tonic arrival instead of letting the harmony stall, keeping repeated choruses in motion.

One progression underlies more music than any other. The ii V I carries the full logic of tonal motion, predominant to dominant to tonic, in three chords, and it appears in Baroque arias, Mozart sonatas, wedding gigs, and bebop heads with equal comfort.

## The major-key form

In C major the progression runs D minor, G major (usually with a seventh), C major. Roman numerals: ii V I. The roots descend by perfect fifth at each step, D to G to C, which is the strongest root motion the style offers.

Two mechanisms make the arrival inevitable. First, the dominant seventh contains a tritone (B to F) that resolves inward by semitone to C and E, squeezing onto the tonic from both sides. Second, the bass walks down a fifth twice, and each fifth-descent sounds like progress toward home. Either device alone would close a phrase; together they are nearly impossible to resist.

Voice leading stays smooth because the chords share pivot tones. D minor and G7 share D; G7 and C share G and E (with E arriving as the resolution of F). Good voicings exploit these common tones so the progression glides instead of jumping. The seventh-chord mechanics behind the dominant are detailed in [seventh chords and resolution](/articles/seventh-chords-and-resolution/).

Extensions begin immediately. Adding VI before the ii creates the turnaround (VI ii V I), and preceding the whole chain with III or I gives longer cycles. But every extension decorates the same core: supertonic preparation, dominant tension, tonic release.

## The minor-key form

Minor keys reshape the supertonic into a half-diminished seventh chord. In A minor: B D F A (iiø7), then E7, then Am. The iiø7 contains a diminished fifth above the root, which darkens the preparation and sharpens the drive.

Melodic choices over the minor ii V I follow the [secondary dominant](/articles/secondary-dominants/) logic: the E7 takes alterations (flat nine, sharp nine) freely, while the iiø7 suits the Locrian color. Classical practice keeps the alterations diatonic-plus-leading-tone; jazz piles them on, treating the dominant as a canvas for upper-structure tension.

A frequent variant substitutes iv6 for iiø6 in first inversion, softening the diminished edge. Another borrows the major-key ii7 into minor contexts for a Dorian tint. Both substitutions keep the predominant function while changing the color, which shows how the progression is a functional slot as much as a fixed chord set.

## Turnarounds and cycles

A turnaround sits at the end of a repeated section and spins the harmony back to the top. The classic jazz turnaround in C runs C A7 Dm7 G7: tonic, applied dominant of ii, ii, V, cycling home. Rhythm changes, the Gershwin-derived form behind countless bebop tunes, builds its entire A section from turnarounds.

The progression also chains through keys. A ii V I in C can be followed by a ii V I in B flat, then A flat, walking the whole chorus down in whole steps. Coltrane-style cycles compress this further with major-third root motion. Each link is elementary; the architecture comes from key choice.

Hear a turnaround loop as three passes of the same engine, each landing back where it started.

The loop above runs I VI7 ii7 V7 in C, the standard vehicle for repeated choruses. Players vary the voicings and substitutions each pass while the functional skeleton stays fixed, which is why rhythm-section musicians can support endless choruses without fatigue.

## The jazz reharm toolkit

Jazz treats ii V I as raw material for substitution. The common moves form a small grammar worth learning in order.

**Tritone substitution** replaces V7 with the dominant seventh a tritone away (D flat 7 for G7 in C). The tritone resolves identically while the bass descends chromatically. Chains of dominants a half step apart come from stacking this move.

**Backdoor resolution** approaches the tonic from iv7 to flat-VII7 instead of ii to V. In C: Fm7 to B flat 7 to C. The flat-VII7 shares two pitches with V7 and resolves smoothly while sounding fresh.

**Diminished passing chords** connect the changes chromatically: C to C sharp diminished to Dm7 fills the whole-step gap with a diminished bridge. Barry Harris systematized these moves into a complete bebop method.

**Modal interchange** borrows the minor ii V (iiø7 V7alt) into major contexts and vice versa. The borrowed darkness resolves into the expected tonic, giving modern players the best of both modes within one turnaround.

Each substitution preserves the functional skeleton while changing the surface. That discipline is what separates reharm from random chords: the ear still hears predominant, dominant, tonic underneath every alteration.

## Where ii V I misleads people

Beginners practice ii V I as a finger pattern and conclude that harmony is chord shapes. The shapes are the residue; the motion is the content. A ii V I played without hearing the tritone resolve and the bass fall is calisthenics, not music. Practice slowly enough to hear each tendency tone land.

Lead-sheet notation hides the voice leading. Dm7 G7 C looks like three equal blocks, but the second chord is unstable and the first is preparatory. Players who accent all three equally sound mechanical. Weight the arrival, lighten the preparation, and let the dominant lean forward.

A subtler trap is forcing ii V I analysis onto music that avoids it. Modal jazz, drones, and much popular music deliberately sidestep dominant function. Labeling a two-chord vamp as a truncated ii V I explains nothing and obscures the actual logic of stasis. Use the progression where the repertoire uses it, which is most places, but not everywhere.

## What to do with it

Play ii V I in all twelve keys around the circle of fifths, major first, then minor. Keep the voicings close and the tempo slow enough that each resolution registers. This is the single most useful keyboard drill in tonal music, and it repays daily repetition for years.

Transcribe three turnarounds from recordings you admire: one stride or swing piano chorus, one bebop head, one modern reharm performance. Write the chord symbols, then reduce each to its functional skeleton. The skeletons will match; the surfaces will differ completely. That gap between skeleton and surface is the improviser's entire art.

Finish by composing an eight-bar progression that uses ii V I three times in three different keys, connected by pivot chords. The exercise forces the progression out of its home key and into modulatory service, which is where [functional harmony](/articles/functional-harmony/) shows its full range: not one cadence but a network of them, spanning the piece.
