Quintal Voicings · Jazz Wiki

Quintal voicings stack perfect fifths instead of thirds or fourths, and the sound they make is wide, open, and rock-solid — less “chord” than “resonant frame.” They’re the natural complement to Quartal Voicings: same non-tertian logic, but spread out to the interval that sits lower and stronger in the overtone series. If quartal comping gives you a tight, floating cluster, quintal voicings give you the same colors stretched into something that rings.

Same notes, wider spacing

A perfect fourth and a perfect fifth are octave-complements of each other (Interval Inversion at work), so every stack of fourths is a stack of fifths read from the top down: C–F–B♭–E♭ from its top note is E♭–B♭–F–C, fifths descending. The pitch classes don’t change; what changes is how wide the voicing spreads. Bill Evans’s famous “So What” voicing is E–A–D–G–B, three stacked fourths capped with a major 3rd, compressed into about an octave and a half. Respell those same five notes as a fifths stack and they sprawl across a much wider span — same harmony, opened out.

The equivalence, stated plainly:

Quartal stack from C: C–F–B♭–E♭ (perfect 4ths, compact)
Quintal stack from C: C–G–D–A–E (perfect 5ths, wide)
Both use the same underlying interval class, just measured in opposite directions

Like quartal stacks, quintal voicings usually skip the 3rd, so on their own they carry no built-in major/minor identity — the bass note decides what the ear hears, the same way it does for a sus chord.

Why fifths win at the bottom of the piano

Play a low third or second on a piano and it turns to mud; play a low fifth (or octave) and it stays clear. That’s not a piano quirk — it’s the low-interval limit: wider, more consonant intervals stay clean in low registers, while narrow intervals need to sit higher. The fifth is also the 3rd partial in the overtone series — a stronger, lower-order overtone than the fourth. Both facts point the same direction: fifths are what you reach for when the bottom of a voicing has to stay stable and grounded.

That’s exactly why McCoy Tyner’s left hand made open fifths its default anchor. Under his dense quartal right-hand stacks, Tyner typically holds a bare root-and-5th low in the left hand — just the open interval that reads clear at that register while staying uncommitted about major or minor. Quintal voicings formalize that same instinct: put the fifths where the piano rewards them (low), and save the busier, more colorful stacking for higher up.

One shape, several chords

A five-note fifths stack from C — C–G–D–A–E — happens to be the C major pentatonic scale respelled in perfect fifths, and depending on what bass note sits under it, it reads as several different chords:

Over a C bass: C6/9 (1–5–9–6–3, reading up — the E here is a real 3rd, so this reading isn’t a no-3rd sound)
Over an A bass: Am11 (root–♭3–11–5–♭7)
Over a G bass: G9sus(add13) (root–9–11–5–13, no 3rd present, a clean suspended color)

The same “one voicing, many chord symbols” trick as quartal harmony, spread wider. A stretch-voicing template for Fm11 makes the two-handed split concrete: left hand F–C–G (root–5–9), right hand A♭–E♭–B♭ (♭3–♭7–11), the hands separated by a half step in the middle of the stack — swap the right-hand notes to A–E–B (3rd–7th–♯11) and the same shape becomes Fmaj9(♯11).

Combining fifths below with fourths above

In practice, most working “quintal” comping isn’t a pure fifths stack — it’s fifths low, with quartal or pentatonic shapes floating on top where the ear can handle more density. Over a static Dm7/D Dorian vamp, that might mean D–A low in the left hand with E–A–D–G–B (or a fifths-spread version of the same notes) in the right — open at the bottom, colorful up top, both hands drawing from the same modal, non-functional pitch pool. This two-register split is the bridge between Quartal Harmony and quintal thinking: not competing systems, one open-fifths-and-fourths vocabulary deployed to match what each register does best.

♫ Listen

McCoy Tyner — “Passion Dance” (The Real McCoy, 1967): the left hand repeatedly grounds the F vamp with a bare root-and-5th pedal under his stacked-fourth right hand — the low open fifth is the exact register logic quintal voicings are built on.
Miles Davis — “So What” (Kind of Blue, 1959): Bill Evans’s compact E–A–D–G–B shape is the reference point — imagine the same five notes stretched into fifths and you hear the compact-vs-spread relationship that separates quartal from quintal.
Herbie Hancock — “Maiden Voyage” (Maiden Voyage, 1965): the bass line moves in fifths under quartal-voiced minor sevenths, a real-world case of fifths-below and fourths-above working as one open, non-functional texture.
