Rise of the Church

The church prospered during a period of economic growth for Europebetween 1050 and 1300.

Donors funded new monasteries and convents.

New religious orders were founded by St. Francis (Franciscans), St.Dominic (Dominicans), St. Clare, and others.

Scholasticism sought to reconcile classical (Greek) philosophy with

Christian doctrine.

Rise of the Church

Large church buildings were erected.

Romanesque style in the eleventh and early twelfth centuries:

Round arches in the style of the Roman basilica

Frescoes and sculptures decorated the buildings.

Gothic style from the mid-twelfth century onward

Tall, spacious buildings with soaring vaults

Slender columns

Large stained-glass windows

PolyphonyAt first, polyphony merely decorated chant in performance, much as

medieval art decorated manuscripts and cathedrals.

Polyphonic pieces added extra grandeur to chants.

Its function as commentary on a chant resembled the process of

troping.

Advances in theory and notation made more elaborate genres

possible.

Precepts of later Western music were established with medieval

polyphony.

Counterpoint, the combination of multiple independent lines

Harmony, the regulation of simultaneous sounds

Notation

Composition, distinct from performancePatrick Donnelly (Montana State University) Music History I Spring 2013 4 / 43

Early Organum

Early Organum has it origins in performance.

Drone:

Singing or playing a melody against a sustained pitch

The drone pitch may have been the modal final, and sometimesthe fifth above as well, as they have been in European folk

traditions.

Doubling in parallel consonant intervals was probably common before

it was explained in anonymous ninth-century treatises.

Ninth-Century Organum

Described in Musica enchiriadis and Scolica enchiriadis

Two or more voices singing different notes in agreeable combinations

Used for several styles of polyphony from the ninth through the

thirteenth centuries

Parallel organum:

Duplication of a chant melody (principal voice)

An organal voice duplicates the chant melody in parallel motion a

fifth below.

In medieval thought, fifths were considered perfect and beautiful

consonances.

Either voice could be doubled at the octave

http://find/


7/43

Mixed Parallel and Oblique Organum

Adjustments were necessary to avoid tritones.

When the chant includes e, the organal voice may not move below c.

When the chant includes b, the organal voice may not move below g.

The organal voice instead remains on one note while the chant voice

moves (oblique motion).

HWM Example 5.2, NAWM 14c, and HWM Figure 5.1 combine oblique

and parallel motion.

Cadences converge on the unison.

These adjustments to parallelism opened the door for more

independent polyphony.

Eleventh-Century Polyphony

Guido of Arezzo described a range of choices in his Micrologus (ca.

1025-28), some of which could be written down instead of improvised.

The Winchester Troper (early eleventh century):

A manuscript from Winchester Cathedral in England

Wulfstan of Winchester (fl. 992-996), cantor at the cathedral, was

the likely composer.

174 organal voices for chant, composed rather than improvised

Free Organum (Late Eleventh Century)

Ad organum faciendum (On Making Organum, ca. 1100) is a set of

instructions with examples.

Organal voice is now usually above the chant rather than below.

Motion is note-against-note (one organal note for each chant note).

Parallel, oblique, and contrary motion are allowed.

Consonances remain the unison, fourth, fifth, and octave.

Cadences on the unison or octave, sometimes preceded by a third or

sixth.

Sung by soloists in solo portions of the Mass and Office

Also sung in troped sections of the Mass Ordinary

Aquitainian Polyphony: The Early Twelfth Century

The main sources:Three manuscripts once held in the Abbey of St. Martial in

Limoges, in Aquitaine, and copied in Aquitainian notation

The Codex Calixtinus, prepared in central France and brought to

the Cathedral of Santiago de Compostela in northwest Spain in

1173

The repertory:

Settings of chant, including sequences, Benedicamus Domino

melodies, and solo portions of responsorial chantMost of the works are versus

11/43

Aquitainian Polyphony: The Early Twelfth Century

Two styles coexisted. Both styles could be used in the same work.

Discant:

Both parts move at about the same rate.

One to three notes in the upper part for each note in the lower

voice

Florid organum:

The lower voice moves more slowly than the upper voice.

For each note in the lower voice the upper voice sings note groups

of varying lengths.

The lower voice is now called tenor (from the Latin tenere, to

hold) because it holds the principal melody.

http://find/


12/43

Aquitainian Polyphony: Notation

Written in score notation with both voices written above the text.

Alignment of the voices suggests both voices sang the words.

Durations are not indicated, leaving many possibilities open.

The tenor proceeds at a steady pace, with the upper voice

speeding up or slowing down depending on the number of notesin the organal style.

The upper voice proceeds at a steady pace, with the tenor

sustaining its pitches in drone-like fashion.

The upper voice uses a type of metered rhythm that was nevernotated or discussed in a treatise, and has therefore been lost to

history

Notre Dame Polyphony:

Late Twelfth and Early Thirteenth Centuries

Musicians associated with the Notre Dame Cathedral of Paris

developed a more ornate style of organum in the late twelfth century.

The cathedral is one of the grandest cathedrals in the Gothic style and

took almost a century to complete.:Foundations for the cathedral were laid in 1160.

The first Mass was celebrated in 1183.

The fade was completed in 1250.

The new repertorys decoration of the authorized chant paralleled the

intricate decoration of the cathedral.

Notre Dame Polyphony

The new repertory was the first to be primarily composed and read

from notation rather than improvised.

The rhythmic modes:

Notation in notegroups indicates patterns of long and short notes.

The six modes use only longs (long notes) and breves (short

notes) in repeating patterns. The basic time unit (tempus, pl. tempora) is grouped in threes. Longs could equal two or three breves. Mode 1: LB Mode 2: BL

Mode 3: L (three breves) B L Mode 4: B B (two breves) L (three breves) Mode 5: all three-breve longas Mode 6: all breves



15/43

Notre Dame Polyphony

The rhythmic modes (contd):A thirteenth-century treatise attributed to Johannes de Garlandia

describes the notation, though it was devised in the twelfth

century.

Ligatures, notegroups based on chant neumes, indicated whichmode by the pattern of groupings.

A three-note ligature followed by a series of two-note ligaturessignaled Mode 1.

In modern transcriptions, ligatures are indicated by horizontalbrackets over the notes.

A piece could change modes, preventing monotony.

Magnus Liber Organi

Great Book of Organum

A treatise from about 1285 known as Anonymous IV names two

musicians associated with creating polyphony for Notre Dame:

Leoninus (1150-ca. 1201)Perotinus (late twelfth and early thirteenth centuries)

Anonymous IV was probably an English student working at Notre

Dame in Paris, most likely in the 1270s or 1280s.

Leoninus (1150 - ca.1201)

Also known as Lonin, Leonius, or

Leo.

He was a canon at Notre Dame

and was affiliated with a nearbymonastery (St. Victor).

He wrote poetic paraphrases of

several books of the Bible.

Perotinus (late twelfth and early thirteenth centuries)

Also known as Ptrotin or Petrotin

He must have held an important

position at the cathedral.

He may have held a master of arts

degree at the school that would

become the University of Paris.

Magnus Liber Organi

Anonymous IVs treatise credits Leoninus with compiling a great book

of polyphony (Magnus liber organi) for use at the Notre Dame

Cathedral.

The original great book no longer exists.The contents survive in several later manuscripts.

Other composers added to the repertory in the great book.

For some chants, several polyphonic settings survive.


Magn s Liber Organi
http://find/


20/43

Magnus Liber Organi

Organum in the style of Leoninus

Sung in two voices

Features two types of polyphony: organum and discant

Only the portions of the chant performed by soloists were sung

polyphonically.

The choir sang the remaining portions in unison.

Memorization of complex polyphony was aided by the use of formulas

and repeating patterns of the rhythmic modes.


Organum Style (Organum Purum)
http://find/


21/43

Organum Style (Organum Purum)

The tenor sustains a chant melody in long notes, like a series of

drones.

The upper voice, called the duplum, sings expansive melismas,

moving mostly stepwise.

Cadences arrive on an octave, fifth, or unison, and are followed by a

rest.

Dissonances sometimes occur and are even prolonged by the organal

voice.

The notation doesnt suggest any mode, but some performers andscholars have tried to apply the rhythmic modes to this style.

Most settings are in organum style.


Discant Style
http://find/


22/43

Discant Style

Both voices move in modal rhythm.

Discant style is generally applied to the long melismas of the chant.

Cadences end on a unison, fifth, or octave, and most longs are perfect

consonances.


Substitute Clausulae


23/43


Perotinus edited the Magnus liber and made many better clausulae.

Clausulae is from the Latin word for a clause or phrase in a sentence.

It was a self-contained section of an organum that closed with a

cadence.

Substitute clausulae replaced original polyphonic settings of a

segment of chant.

Most are in discant style.


http://find/


24/43


The tenor repeats a rhythmic motive based on a rhythmic mode.

The tenor sometimes also repeats the melody over a much longer

span of time.

The repetition of rhythm and melody in the tenor would become

significant in later motets.


Perotinus Organum
http://find/


25/43

Perotinus Organum

Perotinus and his contemporaries created organa for three or even four

voices:

Organum duplum: two-voice organum

Organum triplum: three-voice organum

Organum quadruplum: four-voice organum

Voice names in ascending order from the tenor: duplum, triplum,

quadruplum

Upper voices:

All use rhythmic modes, enabling exact coordination among them.They move in similar ranges, crossing repeatedly.


Viderunt Omnes (ca 1198)

26/43

Viderunt Omnes (ca. 1198)

Anonymous IV attributes this work to Perotinus.

Based on a Gradual.

Begins with organum style

The tenor sustains very long notes.

The upper voices move in modal rhythm.

Passages in discant style alternate with sections of organal style.


Viderunt Omnes (ca 1198)

27/43

Viderunt Omnes (ca. 1198)

Compositional devices give sections in organum style coherence and

variety.

Repeated phrases

Restated phrases at different pitch levels

Complementary phrases

Voice exchange (voices trading phrases)

Striking dissonances that precede consonances

Each section uses distinct techniques.

The upper voices were sung by soloists, with about five singers on thetenor part.


Polyphonic Conductus
http://find/


28/43


Two- to four-voice settings of the Latin poetry:Same type of text as the monophonic conductus and Aquitainian

versus

Rhymed, rhythmic, strophic Latin poems

Usually sacred or serious topics

Tenor was newly composed, not from chant.

All voices sing in essentially the same rhythm, called the "conductus

style" when used in other genres.


http://find/


29/43


Syllabic text-setting:

Simple style

Strophic form

Melismatic passages, called caudae (singular cauda, Latin for tail), in

some conductus:At the beginning and end

Before important cadences

Most conductus with caudae are through-composed.

Sometimes caudae feature phrase repetitions and voiceexchange.


Motet
http://find/


30/43

Motet

Motets are polyphonic works with one or more texted voice added to apre-existing tenor, which is set in a modal rhythm.

Musicians at Notre Dame created this new genre in the early thirteenth

century.

Motets originally consisted of newly written Latin words added to the

upper voices of discant clausulae.

The French word mot (word) inspired the name for the genre.

The earliest texts were often a textual trope of the clausula.

Motet

Later motet texts were written in French on secular topics.

Motets are identified by a compound title comprising the first words of

each voice from highest to lowest.

The motet became the leading polyphonic genre for both sacred and

secular music.

y ( )

The text decorates or tropes the original chant text.

Phrasing of the original clausula dictates phrasing of the added text.

Sung during the Mass or as independent entertainment

Existing motets were reworked:

New texts for the duplum, in Latin or French

New texts were no longer linked to the original liturgical context.

Additional voices were added, with texts of their own.

Double motet: a motet with two added texts above the tenor

Triple motet: a motet with three added texts above the tenor

The original duplum was discarded and another one (or more)

composed.

Motets composed from scratch

A tenor from a clausula was set to a different rhythm.

New voice(s) above the tenor were added.

Fole acostumance/Dominus :

Newly composed duplum in a faster rhythmThe text is in French, with a secular theme.

The upper voice(s) were sung, but it is unclear whether the tenor was

sung or played on an instrument.

Refined and discerning listeners were the intended audience.


Super te/Sed fulsit /Dominus

34/43

p

The top two voices set the first and second halves of one Latin poem.

The topic is the birth of Christ, making it suitable for Christmas (the

season of the original chant).

The upper parts rarely rest together or with the tenor, propelling the

motet forward.

Two other versions have added voices.

A version in the Montpellier Codex, a major source of motets, has

a third texted voice.An English source has an untexted fourth voice.


Motets in the Later Thirteenth Century

y

By about 1250, three-voice motets were the rule.

The two texts were usually on similar topics.

The texts could be in Latin or French.

Some motets had upper voices in both Latin and French.

The tenor became a cantus firmus after ca. 1270.

The term designates any pre-existing melody.

The existing melody continued to be a plainchant.


Franconian Notation
http://find/


36/43

Franconian notation made it possible to signify more rhythms.

Described by Franco of Cologne in his Ars cantus mensurabilis (ca.

1280)

Noteshapes signified relative durations.

Durations consisted of double long, long, breve, and semibreve.

The tempus was the basic unit.

Three tempora constitute a perfection (like a measure).

A long could last two or three tempora.

A breve could last one or two tempora.


Franconian Notation
http://find/


37/43

The system included signs for rests in specific durations as well.

Layout of the parts could be separated:Each part would be in the same book but no longer in score

format.

The tenor extended across the bottom, with the other voice(s)

above.

Franconian motets:

Motets written in Franconian notation, in a style made possible by

that notation

Each upper voice had a distinctive rhythm.

Upper voices no longer needed to conform to the rhythmic modes.

38/43

Written by Adam de la Halle

The triplum part concerns a mans point of view.

The duplum part voices the womans point of view.

The tenor part repeats the omnes melisma from Viderunt omnestwelve times.

The upper parts use a modified first mode rhythm, with many

semibreves.

The phrases are independent, with voices rarely cadencing together.


Pierre de la Croix, fl. ca. 1270-1300
http://find/


39/43

His motets take the Franconian motet one step further.

Each voice has its own pace:

The tenor is very slow-moving.

The duplum is slow-moving, but not as slow as the tenor.

The triplum has as many as seven semibreves in a tempus.

The tempo was probably even slower than in a Franconian motet.


Harmonic Vocabulary
http://find/


40/43

Harmonic vocabulary of motets allowed thirds and dissonances, but

the perfect consonance was still expected at the beginning of each

perfection:

The perfect fourth was treated like a dissonance.

Cadence patterns developed


English Polyphony
http://find/


41/43

English culture was tied to that of France after the Norman Conquest

in 1066.

Although they adopted French culture, English musicians created a

distinct style.

Imperfect consonances were more prominent:Improvised partsinging in close harmony was documented as

early as 1200.

NAWM 21c shows many harmonic thirds and triads, including the

final sonority.

Voice-exchange evolved into elaborate techniques.


English Polyphony

The rondellus, in which two or three phrases are heard simultaneously,

with each voice singing each one in turn:

Triplum: a b cDuplum: c a b

Tenor: b c a

The rota, Sumer is icumen:A rota is a perpetual canon or round at the unison.

Sumer is icumen in is the most famous.

Two voices sing a pes (Latin for "foot" or "ground").

The canon produces alternating F-A-C-F and G-B-flat-Dsonorities.

English melodies are relatively simple, syllabic, and periodic.


A Polyphonic Tradition
http://find/


43/43

By 1300, composition meant creating polyphony, not monophony.

Writing down music of multiple parts in coordinating vertical sonorities

to create a sense of direction would be a hallmark of Western tradition

and set it apart from almost all other musical traditions.

Medieval music rarely outlived its composers, but in the late nineteenth

and early twentieth centuries, composers drew on medieval music as

an exotic element, making it seem more familiar to listeners.
