The V7sus4 Chord · Jazz Wiki

Take a Dominant Seventh Chord, pull out the note that gives it its bite, and you get one of the most useful sounds in modern jazz. The V7sus4 chord replaces the major 3rd with a perfect 4th, which quietly disarms the chord’s built-in urge to resolve. The result is a sound that can still function as a dominant if you want it to, or just hang in the air indefinitely — which is exactly why it became the harmonic signature of 1960s modal jazz.

What actually changes when you remove the 3rd

A dominant 7th chord gets its pull from The Tritone between the 3rd and ♭7th — in G7, that’s B and F, a dissonant interval that wants to snap inward to C and E. Swap the B for a C (the 4th) and that tritone disappears entirely, since C and F are just a perfect 4th apart, not a tritone.

G7: G – B – D – F (contains the B–F tritone)
G7sus4: G – C – D – F (no tritone; B is gone)

Without the tritone, Dominant Resolution becomes optional rather than mandatory. The chord still smells like a dominant because of its root and 7th, but it no longer demands to go anywhere.

Spellings, slash chords, and how it resolves

The sus4 chord is really just The Related ii Chord stacked over the V root — which is why it shows up constantly as a slash chord in lead sheets.

G7sus4: G – C – D – F (root, 4th, 5th, ♭7th — no 3rd)
Equivalent slash spellings: Dm7/G, F/G
Traditional resolution: G7sus4 → G7 → Cmaj7 (4th falls to 3rd, then dominant resolves)
Modern resolution: G7sus4 → Cmaj7 directly, skipping the G7 step entirely
No resolution at all: G7sus4 held as a static color, common in modal writing

In a full The ii-V-I Progression, the sus chord often just absorbs the V chord’s beat or two: Dm7 – G7sus4 – Cmaj7, with the suspended sound smoothing the seam between ii and I rather than sharpening it.

The traditional resolution shows the 4th falling to the 3rd before the dominant resolves:

And here the sus chord absorbs the V in a full ii-V-I:

Why the scale choice matters

Improvising over a sus4 chord means picking a scale that doesn’t fight the chord tones. The default choice is Mixolydian Mode built on the root — G Mixolydian (G–A–B–C–D–E–F) over G7sus4 — but that scale contains a B, the very note the chord went out of its way to avoid.

Many players simply treat the M3 as unusable in the lower register and save it for a passing tone or upper color
Others borrow from Dorian (treating the chord like Dm7/G) to sidestep the M3/P4 clash altogether
In practice, the “wrong” 3rd against the 4th a whole step below is often used deliberately — a 7sus4(add3) sound heard constantly in Herbie Hancock’s and Wayne Shorter’s writing

Voicings: it’s already a quartal chord

Because its defining interval is a 4th rather than a 3rd, the V7sus4 is naturally suited to Quartal Voicings — stacked 4ths instead of stacked 3rds. McCoy Tyner built an entire piano vocabulary out of this: left hand holding a rootless shell, right hand stacking 4ths on top, no 3rd anywhere in the voicing.

Quartal voicing of C7sus4: C (bass) with G – C – F – B♭ stacked in fourths above (5 – 1 – 4 – ♭7)
Shell voicing: root and ♭7 in the left hand, ii-chord upper structure in the right

Held over a static Pedal Point, these voicings stop functioning as “dominant chords waiting to resolve” and start functioning as Modal Harmony — color and mood rather than Tension and Release in the classical sense. This is the real shift the sus chord enabled: harmony that breathes instead of pulling.

A Tyner-style quartal grip, moved in parallel motion for a modal sus vamp:

G7sus4

No 3rd anywhere in the grip — the 4th and ♭7 stack in fourths above the root

A7sus4

The same grip slid up two frets — parallel motion, Tyner-style, for the modal vamp

♫ Listen

Herbie Hancock — “Maiden Voyage” (Maiden Voyage, 1965): the whole tune is built on a cycle of unresolved sus chords moving in parallel (D7sus and F7sus in the A sections, E♭7sus and F♯7sus on the bridge). Listen for how the harmony just floats — there’s no cadence pulling you anywhere, which is the entire point.
McCoy Tyner — “Passion Dance” (The Real McCoy, 1967): Tyner’s left hand comps in stacked 4ths under his own solo, showing exactly how a sus4 chord becomes quartal harmony in real time.
John Coltrane — “Naima” (Giant Steps, recorded 1959, released 1960): the melody sits over suspended harmony built on E♭ and B♭ pedal tones, letting the tune hover rather than resolve — an early, lyrical preview of what modal players would later do more overtly.
