The Notre Dame school or the Notre Dame school of polyphony refers to the group of composers working at or near the Notre Dame Cathedral in Paris from about 1160 to 1250, along with the music they produced.
The only composers whose names have come down to us from this time are Léonin and Pérotin. Both were mentioned by an anonymous English student, known as Anonymous IV, who was either working or studying at Notre Dame later in the 13th century. In addition to naming the two composers as "the best composers of organum," and specifying that they compiled the big book of organum known as the Magnus Liber Organi, he provides a few tantalizing bits of information on the music and the principles involved in its composition. Pérotin is the first composer of organum quadruplum—four-voice polyphony—at least the first composer whose music has survived, since complete survivals of notated music from this time are scarce.
Léonin was the first known significant composer of polyphonic organum. He was probably French, probably lived and worked in Paris at the Notre Dame Cathedral and was the earliest member of the Notre Dame school of polyphony and the ars antiqua style who is known by name. The name Léonin is derived from "Leoninus," which is the Latin diminutive of the name Leo; therefore it is likely that Léonin's given French name was Léo.
Perotinus Magnus, was a composer from around the late 12th century, associated with the Notre Dame school of polyphony in Paris and the ars antiqua musical style. The title Magister Perotinus, means that he was licensed to teach. The only information on his life with any degree of certainty comes from an anonymous English student at Notre Dame known as Anonymous IV. It is assumed that he was French and named Pérotin, a diminutive of Peter, but attempts to match him with persons in other documents remain speculative.
Anonymous IV is the designation given to the writer of an important treatise of medieval music theory. He was probably an English student working at Notre Dame in Paris, most likely in the 1270s or 1280s. Nothing is known about his life, not even his name. His writings survive in two partial copies from Bury St Edmunds; one from the 13th century, and one from the 14th.
Léonin, Pérotin and the other anonymous composers whose music has survived are representatives of the era of European music history known as the ars antiqua. The motet was first developed during this period out of the clausula, which is one of the most frequently encountered types of composition in the Magnus Liber Organi.
Ars antiqua, also called ars veterum or ars vetus, is a term used by modern scholars to refer to the Medieval music of Europe during the High Middle Ages, between approximately 1170 and 1310. This covers the period of the Notre Dame school of polyphony, and the subsequent years which saw the early development of the motet, a highly varied choral musical composition. Usually the term "ars antiqua" is restricted to sacred (church) or polyphonic music, excluding the secular (non-religious) monophonic songs of the troubadours, and trouvères. However, sometimes the term "ars antiqua" is used more loosely to mean all European music of the thirteenth century, and from slightly before. The term ars antiqua is used in opposition to ars nova, which refers to the period of musical activity between approximately 1310 and 1375.
In western music, a motet is a mainly vocal musical composition, of highly diverse form and style, from the late medieval era to the present. The motet was one of the pre-eminent polyphonic forms of Renaissance music. According to Margaret Bent, "a piece of music in several parts with words" is as precise a definition of the motet as will serve from the 13th to the late 16th century and beyond. The late 13th-century theorist Johannes de Grocheo believed that the motet was "not to be celebrated in the presence of common people, because they do not notice its subtlety, nor are they delighted in hearing it, but in the presence of the educated and of those who are seeking out subtleties in the arts".
In late medieval Western music, a clausula was a newly composed polyphonic section for two or more voices sung in discant style over a cantus firmus. Clausulae eventually became used as substitutes for passages of original plainchant. They occur as melismatic figures based on a single word or syllable within an organum. The text of a clausula differs from that of the plainchant melody underneath it. Each clausula is clearly delineated by a final cadence.
While music with notation has survived, in substantial quantity, the interpretation of this music, especially with regard to rhythm, remains controversial. Three music theorists describe the contemporary practice: Johannes de Garlandia, Franco of Cologne, and Anonymous IV. However, they were all writing more than two generations after the music was written, and may have been imposing their current practice, which was quickly evolving, on music which was conceived differently. In much music of the Notre Dame School the lowest voices sing long note values while the upper voice or voices sing highly ornamented lines, which often use repeating patterns of long and short notes known as the "rhythmic modes." This marked the beginning of notation capable of showing relative durations of notes within and between parts (Hoppin 1978, p.221).
Johannes de Garlandia was a French music theorist of the late ars antiqua period of medieval music. He is known for his work on the first treatise to explore the practice of musical notation of rhythm, De mensurabili musica; prior to this time, music notation applied to pitch only.
Franco of Cologne was a German music theorist and possibly a composer. He was one of the most influential theorists of the late Medieval era, and was the first to propose an idea which was to transform musical notation permanently: that the duration of any note should be determined by its appearance on the page, and not from context alone. The result was Franconian notation.
Notre Dame motets
The earliest motets are the Notre Dame motets, written by composers such as Leonin and Perotin during the 13th century. These motets were polyphonic, with a different text in each voice, and employed the rhythmic modes. An example of a Notre Dame motet is Salve, salus hominum/O radians stella/nostrum by Perotin, composed between 1180 and 1238.
Contemporary accounts
With polyphony, musicians were able to achieve musical feats perceived by many as beautiful, and by others, distasteful (Kirkman 2010, p.163 n.72). John of Salisbury (1120–1180), philosopher and Bishop of Chartres, taught at the University of Paris during the years of Léonin, but before Pérotin, was one of the latter. He attended many services at the Notre Dame Choir School. In his Policraticus he offers a first-hand description of what was happening to music in the High Middle Ages, writing (Hayburn 1979, p.18):
In music, polyphony is one type of musical texture, where a texture is, generally speaking, the way that melodic, rhythmic, and harmonic aspects of a musical composition are combined to shape the overall sound and quality of the work. In particular, polyphony consists of two or more simultaneous lines of independent melody, as opposed to a musical texture with just one voice, monophony, or a texture with one dominant melodic voice accompanied by chords, which is called homophony.
John of Salisbury, who described himself as Johannes Parvus, was an English author, philosopher, educationalist, diplomat and bishop of Chartres, and was born at Salisbury, England.
The Roman Catholic Diocese of Chartres is a Roman Catholic Latin Rite diocese in France.
Bad taste has, however, degraded even religious worship, bringing into the presence of God, into the recesses of the sanctuary a kind of luxurious and lascivious singing, full of ostentation, which with female modulation astonishes and enervates the souls of the hearers. When you hear the soft harmonies of the various singers, some taking high and others low parts, some singing in advance, some following in the rear, others with pauses and interludes, you would think yourself listening to a concert of sirens rather than men, and wonder at the powers of voices … whatever is most tuneful among birds, could not equal. Such is the facility of running up and down the scale; so wonderful the shortening or multiplying of notes, the repetition of the phrases, or their emphatic utterance: the treble and shrill notes are so mingled with tenor and bass, that the ears lost their power of judging. When this goes to excess it is more fitted to excite lust than devotion; but if it is kept in the limits of moderation, it drives away care from the soul and the solicitudes of life, confers joy and peace and exultation in God, and transports the soul to the society of angels. (John of Salisbury 1938, Book I Chapter 6)

Medieval music consists of songs, instrumental pieces, and liturgical music from about 500 A.D. to 1400. Medieval music was an era of Western music, including liturgical music used for the church, and secular music, non-religious music. Medieval music includes solely vocal music, such as Gregorian chant and choral music, solely instrumental music, and music that uses both voices and instruments. Gregorian chant was sung by monks during Catholic Mass. The Mass is a reenactment of Christ's Last Supper, intended to provide a spiritual connection between man and God. Part of this connection was established through music. This era begins with the fall of the Western Roman Empire in the fifth century and ends sometime in the early fifteenth century. Establishing the end of the medieval era and the beginning of the Renaissance music era is difficult, since the trends started at different times in different regions. The date range in this article is the one usually adopted by musicologists.
Organum is, in general, a plainchant melody with at least one added voice to enhance the harmony, developed in the Middle Ages. Depending on the mode and form of the chant, a supporting bass line may be sung on the same text, the melody may be followed in parallel motion, or a combination of both of these techniques may be employed. As no real independent second voice exists, this is a form of heterophony. In its earliest stages, organum involved two musical voices: a Gregorian chant melody, and the same melody transposed by a consonant interval, usually a perfect fifth or fourth. In these cases the composition often began and ended on a unison, the added voice keeping to the initial tone until the first part has reached a fifth or fourth, from where both voices proceeded in parallel harmony, with the reverse process at the end. Organum was originally improvised; while one singer performed a notated melody, another singer—singing "by ear"—provided the unnotated second melody. Over time, composers began to write added parts that were not just simple transpositions, thus creating true polyphony.
Ars nova refers to a musical style which flourished in France and the Burgundian Low Countries in the late Middle Ages: more particularly, in the period between the preparation of the Roman de Fauvel (1310s) and the death of composer Guillaume de Machaut in 1377. The term is sometimes used more generally to refer to all European polyphonic music of the fourteenth century. For instance, "Italian ars nova" is sometimes used to denote the music of Francesco Landini and his compatriots. The "ars" in "ars nova" can be read as "technique", or "style". The term was first used in two musical treatises, titled Ars novae musicae by Johannes de Muris, and a collection of writings attributed to Philippe de Vitry often simply called "Ars nova" today. However, the term was first used to describe an historical era only by Johannes Wolf in 1904.
In medieval music, conductus is a type of sacred, but non-liturgical vocal composition for one or more voices. The word derives from Latin conducere, and the conductus was most likely sung while the lectionary was carried from its place of safekeeping to the place from which it was to be read. The conductus was one of the principal types of vocal composition of the ars antiqua period of medieval music history.
In medieval music, the rhythmic modes were set patterns of long and short durations. The value of each note is not determined by the form of the written note, but rather by its position within a group of notes written as a single figure called a "ligature", and by the position of the ligature relative to other ligatures. Modal notation was developed by the composers of the Notre Dame school from 1170 to 1250, replacing the even and unmeasured rhythm of early polyphony and plainchant with patterns based on the metric feet of classical poetry, and was the first step towards the development of modern mensural notation. The rhythmic modes of Notre Dame Polyphony were the first coherent system of rhythmic notation developed in Western music since antiquity.
The Magnus Liber or Magnus Liber Organi contained a repertory of medieval music known as organum in use by the Parisian School of Notre Dame around the turn of the 12th & 13th centuries and is known from references to a "magnum volumen" by Johannes de Garlandia and to a "Magnus liber organi de graduali et antiphonario pro servitio divino" by the English music theorist known simply as Anonymous IV. Today it is known only from later manuscripts containing pieces named in Anonymous IV's description.
Discant or descant originated as a style of liturgical setting in the Middle Ages, associated with the development of the Notre Dame school of polyphony.
Benedicamus Domino is a closing salutation that was formerly used in the Roman Mass instead of the Ite, missa est in Masses which lack the Gloria. The response, said afterwards, is Deo gratias. It is also sung as a versicle at the end of all Offices.
The Montpellier Codex is an important source of 13th-century French polyphony. The Codex contains 336 polyphonic works probably composed c. 1250–1300, and was likely compiled c. 1300. It is believed to originate from Paris. It was discovered by musicologist Edmond de Coussemaker in c. 1852.
In music, especially Schenkerian analysis, a voice exchange is the repetition of a contrapuntal passage with the voices' parts exchanged; for instance, the melody of one part appears in a second part and vice versa. It differs from invertible counterpoint in that there is no octave displacement; therefore it always involves some voice crossing. If scored for equal instruments or voices, it may be indistinguishable from a repeat, although because a repeat does not appear in any of the parts, it may make the music more interesting for the musicians. It is a characteristic feature of rounds, although not usually called such.
With regard to early polyphony the term copula has a variety of meanings. At its most basic level, it can be thought of as the linking of notes together to form a melody. "A copula is a rapid, connected discant..." However, it is often considered to be a particular type of polyphonic texture similar to organum, but with modal rhythm. The music theorist Johannes de Garlandia favoured this description of copula. The term refers to music where the lower voice sings long, sustained notes while the higher voices sing faster-moving harmony lines. This style is typical of what is referred to as Notre Dame Polyphony; examples of which can be found in the Magnus Liber Organi. Copula might have implied a strophic construction with much repetition in the various parts, which was characteristic of much of the music written in this idiom. The upper part consists of "antecedent-consequent" phrases, themselves featuring much melodic repetition. The rhythm is notated in copula, unlike in organum. It is, in essence, the "coming together" of these two parts at the cadence that led to the term copula being used, from the Latin meaning "that binds."
Friedrich Ludwig was a German historian, musicologist, and college instructor. His name is closely associated with the exploration and rediscovery of medieval music in the 20th century, particularly the compositional techniques of the Ars Nova and the isorhythmic motet.
