Cadences in Jazz · Jazz Wiki

A cadence is the harmonic punctuation mark of a phrase — the chord move that tells your ear “this is a comma” or “this is a period.” Every style of tonal music leans on cadences to create Tension and Release, but jazz reshapes the vocabulary it inherited from classical harmony into something built almost entirely around one workhorse: the ii–V–I. Learn to hear cadences and you start hearing the skeleton underneath every standard, not just the melody sitting on top of it.

The authentic cadence, jazz style

In classical harmony the authentic cadence is simply V–I. Jazz almost never plays it that bare — it prepends a supertonic chord and calls the whole three-chord unit a cadence:

Dm7 – G7 – Cmaj7 (ii–V–I in C)
Dm7 – G7♭9 – Cmaj7 (with a dominant alteration)
Gm7 – C7 – Fmaj7 (ii–V–I in F)

This is Dominant Resolution at work: the G7’s guide tones (B and F) each sit a half step from a note of the C major triad — B rises to C, F falls to E — so the chord has to resolve — that pull is the whole engine of Functional Harmony. Because the ii chord shares two notes with the V chord, the ii–V–I reads as one long dominant gesture rather than three separate events, and its smooth voice leading (especially the 3–7 guide-tone line) is why it sounds so inevitable once your ear knows it.

The 3rd and 7th of each chord trace the guide-tone line directly — notice the common tones and half-step motion:

Minor-key and backdoor variants

Minor keys use the same logic with a half-diminished supertonic and an altered dominant — this is The Minor ii-V-i:

Dø7 – G7♭9 – Cm (iiø7 – V7♭9 – i in C minor)

Jazz and blues also have a cadence classical harmony doesn’t really offer: the backdoor progression, approaching the tonic from a flat-VII7 instead of the dominant.

Fm7 – B♭7 – Cmaj7 (iv7 – ♭VII7 – I, full form)
B♭7 – Cmaj7 (shortened backdoor)

Because ♭VII7 has no leading tone pulling up to the tonic, the backdoor resolves by contrary, stepwise motion instead of tension-and-snap — it feels relaxed and a little bluesy rather than urgent, which is exactly why it shows up so often in blues tunes and ballads. It’s also a close cousin of the minor iv chord borrowed from the parallel minor, and of Modal Interchange more broadly.

Deceptive and half cadences: keeping the phrase open

Not every arrival needs to land on the tonic. Two cadence types exist specifically to avoid full closure:

G7 – Am7 (deceptive cadence — Deceptive Resolution: V7 resolves up a step instead of down a fourth)
(any chord) – G7 (half cadence — ends on the dominant, unresolved)

The deceptive cadence takes the dominant’s pull and redirects it somewhere unexpected, which suspends the phrase and often sets up a second, stronger cadence right behind it. The half cadence does the opposite job of an authentic cadence: instead of closing a section, it holds it open, which is why you hear it constantly at the midpoint of a form or right before a soloist enters.

Cadences are not turnarounds

It’s easy to blur these two together, but they do opposite jobs. A cadence resolves to a stable chord and closes a phrase; a turnaround starts on the tonic and deliberately ends on a tension chord so the form can loop back to the top. Jazz players constantly dress up cadential ii–V–I’s with Tritone Substitution (replacing V7 with ♭II7) or extra chromatic dominants, but the underlying job — arrival versus launch — stays distinct. Recognizing which one you’re inside of is essential to phrasing solos and comping with real harmonic intent, and it only clicks once you’ve mapped a few full forms like Autumn Leaves or All the Things You Are and watched where the cadences actually fall.

♫ Listen

Bill Evans — “Autumn Leaves” (Portrait in Jazz, 1959): the trio’s crystalline voice-leading makes the major ii–V–I (Cm7–F7–B♭maj7) and the minor ii–V–i (Am7♭5–D7–Gm7) audible back to back at the top of each A section.
Cannonball Adderley — “Autumn Leaves” (Somethin’ Else, 1958): the saxophone melody outlines the same cadential motion while Hank Jones’s comping punctuates each ii–V–I clearly underneath.
Charlie Parker and Dizzy Gillespie — “All the Things You Are” (Jazz at Massey Hall, 1953): rapid modulating ii–V–I’s, roughly two chords per bar — a masterclass in bebop cadential navigation across keys.
Miles Davis — “So What” (Kind of Blue, 1959): built on D Dorian with no traditional authentic cadence at all — a useful contrast for hearing what harmony sounds like when cadential resolution is deliberately withheld.
