3rd 3rd the sweet, full sound of the English triad

John Dunstaple

c. 1390–1453 · The Contenance Angloise & the Sweetness of Thirds

The English master whose full, sweet triadic harmony crossed the Channel and gave Continental music a new sound — the contenance angloise, the "English manner" that Du Fay and Binchois were said to have made their model.

01 — THE MAN

Who Was John Dunstaple?

John Dunstaple (also spelt Dunstable, c. 1390–1453) was the leading English composer of the early fifteenth century — a musician so admired abroad that his name became shorthand for a whole new, sweeter way of writing music. He was also an astronomer and mathematician, and served in the household of John, Duke of Bedford, the English regent in France.

English

Almost certainly from Dunstable in Bedfordshire; active in England and, through his patron, in Lancastrian France.

Polymath

A serious astronomer and mathematician as well as a composer — his epitaph praised both his skills.

Courtly service

Linked to the household of John, Duke of Bedford, and to noble and royal patronage of his day.

Sacred music

Best known for motets and Mass movements — sweet, consonant, and widely copied on the Continent.

Much about his life is uncertain; the spelling of his own name varies in the sources, and dates are approximate.

02 — A LIFE IN OUTLINE

Dunstaple in His Century

Dunstaple's life spans the Hundred Years' War and the height of English power in France — the very conditions that carried his music across the Channel to the Burgundian and French courts.

c. 1390BornProbably at or near Dunstable, Bedfordshire — hence the name. The early life is largely undocumented.
1420s–30sBedford's serviceAssociated with John, Duke of Bedford, regent of Lancastrian France — a plausible route for English style to reach the Continent.
1441/2Martin le Franc names himThe poet's Le Champion des dames credits the contenance angloise and says Du Fay and Binchois followed Dunstaple.
24 Dec 1453Death in LondonHis tomb in the church of St Stephen Walbrook recorded his death and hailed him as an astronomer and musician.
c. 1477Tinctoris looks backThe theorist Johannes Tinctoris names Dunstaple as the head of the English who founded a "new art".

The famous epitaph was lost when the church burned in the Great Fire of London (1666), but its text survives in copies.

03 — THE ENGLISH MANNER

The Contenance Angloise

Around 1441–2 the poet Martin le Franc, in his long poem Le Champion des dames, described a fresh, joyful sound in the music of Guillaume Du Fay and Gilles Binchois. Its source, he said, was English — the contenance angloise, the "English countenance" or manner — and its model was Dunstaple.

"For they have a new way of making lively concord... They took on the English guise and followed Dunstaple, and thereby a marvellous pleasingness makes their music joyous and remarkable."

— Martin le Franc, Le Champion des dames, c. 1441–2 (translated from the Old French)

This is one of the earliest moments a national "style" is named in Western music — and it is named after an Englishman.

04 — THE EAR BEFORE DUNSTAPLE

Perfect Fifths, Imperfect Thirds

To hear why Dunstaple sounded new, remember what came before. Medieval theory ranked intervals: the unison, octave, fifth and fourth were the perfect consonances — the open, ringing pillars of the sound. Thirds and sixths were only imperfect consonances, colourful but restless, never the goal of a phrase.

PERFECT CONSONANCES — the medieval pillars Unison & Octave Fifth (3:2) Fourth (4:3) open, hollow, "finished" IMPERFECT CONSONANCES — colour, not rest Third (major/minor) Sixth (major/minor) warm, "sweet" — but leaning onward

The English fondness for thirds and sixths was noted well before Dunstaple, but his generation raised it into a whole harmonic style.

05 — THE NEW SOUND

The Sweetness of Thirds & Sixths

Dunstaple and his English contemporaries filled their music with full triads — the root, its third and its fifth sounding together — moving in smooth, consonant chains. To ears trained on bare fifths and fourths, this warm, saturated sound was a revelation: it seemed to glow.

Five ascending root-position triads, in equal temperament, so the thirds ring sweet and in tune — this is the English sound

G · A · B · C · D

Each chord = root (blue) + third (green) + fifth (amber), stacked and rising together.

06 — WHY IT SOUNDS SWEET

Tuning: Why the Third Turned Sweet

The third's bad medieval reputation was partly a matter of tuning. In the old Pythagorean system, built from pure fifths, the major third is wide and buzzing — genuinely harsh. Sweeten the thirds (as English singers did by ear, and as our modern equal temperament approximates) and the very same chords turn mellow and pure.

Play them one after the other: the identical chords, first with the medieval wide thirds, then softened into the "English" sweetness

Pythagorean thirds

Derived from stacked pure fifths, the major third (ratio 81:64) is noticeably wide and restless — which is why theory kept it "imperfect".

Sweetened thirds

Pull the third close to the pure ratio 5:4 and it locks into place — calm, consonant, "sweet". This is the sound the English cultivated.

07 — READING THE MUSIC

Faburden: A Chain of 6–3 Chords

The English technique of faburden harmonised a plainchant almost entirely in sweet triadic sonorities. The result is a chain of 6–3 chords — what we would call first-inversion triads. Here is how to read one on the staff.

6 3 top voice chant (middle) cadence: bottom drops to an open 5th/8ve

The chant sits in the middle

The borrowed plainsong melody (green) is the mean — everything is built around it.

A third below, a sixth above

A voice runs a third under the chant; another a fourth above it — so the outer voices are a sixth apart. Read each stack top-to-bottom.

Open at the cadence

At phrase-ends the lowest voice drops to a fifth below, opening the sweet chords onto a hollow, "perfect" close.

08 — TWO SIDES OF A COIN

Faburden & Fauxbourdon

The Continent had its own way of spinning out these sweet parallel chords — fauxbourdon, prominent in Du Fay. It reaches the identical 6–3 sound as English faburden, but arranges the given melody differently: two cousins, one family resemblance.

Faburden (English)

The plainchant is the middle voice. A voice sings a fourth above it, another mostly a third below — an improvised English descant, sung from the chant book by ear.

Result: a stream of 6–3 chords, opening to a 5th/octave at cadences.

Fauxbourdon (Continental)

The chant-derived melody is on top. The lowest voice is written a sixth below it; a middle voice is improvised a fourth beneath the top.

Result: the same parallel 6–3 chords — sweetness, arrived at from the other direction.

Scholars still debate which came first and how they influenced each other — but both belong to the same mid-fifteenth-century taste for full, consonant harmony.

09 — A MASTERPIECE

Quam pulchra es

Dunstaple's motet Quam pulchra es ("How beautiful you are") sets words from the Song of Songs. Instead of an elaborate cantus firmus, it is largely note-against-note: the voices declaim the text together, moving in gentle thirds and sixths. The sweetness is the argument — harmony as devotion.

♪ Listen: Dunstaple — Quam pulchra es (recording)

A serene, Quam pulchra es-style duet: the two voices open a sixth apart, then glide in parallel thirds — equal temperament keeps them sweet

The style is often called "declamatory" — the words drive the rhythm, and the harmony simply glows around them.

10 — THE LEARNED SIDE

Veni Sancte Spiritus & the Isorhythmic Motet

Dunstaple was no mere melodist. His four-voice motet Veni Sancte Spiritus shows him a master of the old intellectual craft too: the isorhythmic motet, where a repeating rhythmic pattern (talea) is laid over a repeating melody (color) in the tenor, structuring the whole work like architecture in sound.

TALEA — the repeating rhythm same rhythm, stated again → COLOR — the repeating melody (tenor pitches) talea and color cycle at different lengths, weaving the structure

Isorhythm was the great structural device of the Ars Nova; Dunstaple pours the new English sweetness into its rigorous frame.

11 — BEYOND MUSIC

The Astronomer-Composer

Dunstaple belonged to an age when music was still a branch of mathematics — one of the seven liberal arts, sister to arithmetic, geometry and astronomy. He was a serious astronomer and mathematician: manuscripts of astronomical tables and treatises are associated with his name.

His lost epitaph praised him as a man who had "shut up the heavens in his breast" — an astrologer and mathematician as much as a musicus. The proportion and balance we hear in his music are of a piece with that ordered, number-loving mind.

A reminder that the "sweetness" of his harmony rested on the same numerical understanding of intervals that governed his study of the stars.

12 — THE INFLUENCE

The English Seed on the Continent

Carried abroad by war, diplomacy and the copying of manuscripts, the English sound helped shape the Burgundian style that dominated the next generation. What le Franc heard in 1441 became the mainstream of European music.

Guillaume Du Fay

The towering Burgundian master, said to have taken the contenance angloise as a model; a great cultivator of fauxbourdon.

Gilles Binchois

The supreme songsmith of the Burgundian court, named alongside Du Fay as heir to the sweet English manner.

A new default

Full triadic harmony, thirds and sixths as the norm — the foundation on which Ockeghem, Josquin and the whole Renaissance would build.

From here, the "imperfect" consonances become the very heart of Western harmony — and never look back.

13 — THE SOURCES

Where the Music Survives

A telling irony: much of Dunstaple's music comes down to us not through English books but through Continental manuscripts. English liturgical books were largely destroyed in the Reformation — so the very copies that prove how far his fame travelled are the ones that saved his work.

The Trent Codices

A vast mid-fifteenth-century group of manuscripts from the Alps, preserving a huge amount of the sacred polyphony of the age — including English music.

Continental copies

Sources in Italy and elsewhere transmit motets and Mass movements attributed to Dunstaple, showing how widely he was sung abroad.

Attribution puzzles

The same piece can appear under different names in different books, so scholars must weigh conflicting attributions with care.

A lost home tradition

The near-total loss of English sources makes these foreign witnesses precious — and reminds us how much has vanished.

Modern collected editions reconstruct his output by comparing these scattered, and sometimes disagreeing, manuscript sources.

14 — LISTENING GUIDE

How to Listen to Dunstaple

  • Listen for the full chords — root, third and fifth all sounding — and notice how settled and warm they feel.
  • Follow the parallel motion of faburden/fauxbourdon: whole phrases gliding in sweet 6–3 sonorities.
  • Hear how the voices declaim the words together in Quam pulchra es — harmony serving the text.
  • At cadences, catch the chords opening onto a hollow fifth or octave — the old medieval "perfect" close, kept for the finish.

Ensembles specialising in medieval English polyphony bring out the ringing thirds best in resonant, church-like acoustics.

15 — LEGACY

The Man Who Made Harmony Sweet

With Dunstaple, the third and the sixth step out of the shadows and become the warm centre of Western harmony. The contenance angloise he embodied reshaped Continental music; the full triad he loved is, quite simply, the chord we still hear today. To follow the sweetness of thirds is to trace the birth of the sound of the Renaissance.

Sweet harmony

Thirds and sixths, once "imperfect", become the everyday consonances of European music.

A named style

The contenance angloise is among the first national manners consciously imitated across Europe.

The road to Du Fay

Dunstaple's sweetness feeds directly into the Burgundian school and the whole Renaissance to come.

"The fount and origin of this new art is held to be among the English, of whom Dunstaple stood forth as the chief."

— Johannes Tinctoris, Proportionale musices, c. 1476–7 (paraphrased from the Latin)

c. 1390 – 1453 · the Englishman who taught Europe to love the third.
