The Magnus Liber or Magnus liber organi (English translation: Great Book of Organum), written in Latin, is a repertory of medieval music known as organum. This collection of organum survives today in three major manuscripts. This repertoire was in use by the Notre-Dame school composers working in Paris around the end of the twelfth and beginning of the thirteenth centuries, though it is well agreed upon by scholars that Leonin contributed a bulk of the organum in the repertoire. This large body of repertoire 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 as Anonymous IV. [1] [2] Today it is known only from later manuscripts containing compositions named in Anonymous IV's description. The Magnus Liber is regarded as one of the earliest collections of polyphony.

Surviving Manuscripts

The Magnus Liber organi most likely to have originated in Paris and is known today from only a few surviving manuscripts and fragments, and there are records of at least seventeen lost versions. [1] Today its contents can be inferred from the three surviving major manuscripts:

These three manuscripts date from later than the original Magnus Liber, but careful study has revealed many details regarding origin and development. [4] "Evidence of lost Notre Dame manuscripts, including the names of their owners, is plentiful indeed", [1] tracing back to year 1456 when manuscript F first appeared in the library of Piero de' Medici. Of the two others, referred to as W1 & W2, both in the Herzog August Bibliothek (Ducal Library), the first is thought to have originated in the cathedral priory of St Andrews, Scotland, and less is known about W2. Catalogues referring to other lost copies attest to the wide diffusion through Western Europe of the repertoire later called ars antiqua .

Heinrich Husmann summarizes that "these manuscripts, then, do not represent any more the original state of the Magnus Liber, but rather enlarged forms of it, differing from each other. In fact, these manuscripts embody different stylistic developments of the Magnus Liber itself, particularly in the field of composition mentioned by Anonymous IV, the clausula. This is born out by the differing versions of the discantus parts". [5]  Husmann also notes that a comparison of the repertory contained in the three manuscripts shows there "are a great many pieces common to all three sources" and that "the most reasonable attitude is obviously to consider the pieces in common to all three sources as the original body, consequently as the true Magnus Liber organi". [5]

Contributors to the Liber

It is unknown whether the MagnusLiber had one sole contributor, though it is noted by scholars that large parts were composed by Léonin (1135–c.1200) and this conclusion is drawn from the writings of Anonymous IV. [3]  Though it is a controversial topic among scholars, some believe parts of the Magnus Liber organi may have been revised by Pérotin (fl. 1200), while others such as Heinrich Husmann note that the finding is from 'the rather slim report of Anonymous IV' and that 'as for its connections with Notre Dame Cathedral in Paris, the name of Pérotin alone is adduced' in connection with his books having only been used. This 'by no means confirms that Pérotin himself was active at Notre Dame, or anywhere else in Paris for that matter'. [6]

The music from the Liber has been published in modern times by William Waite (1954), [7] Hans Tischler (1989), [8]  and by Edward Roesner (1993–2009). [9]

Styles and Genres of the Repertoire

Folio 8 of manuscript F

The early music of Notre Dame cathedral represents a transitional time for Western culture. This time of change coincided with the architectural innovation that produced the structure of the Cathedral itself (earliest start of construction in 1163). A handful of surviving manuscripts demonstrate the evolution of polyphonic elaboration of the liturgical plainchant that was used at the cathedral every day throughout the year. While the concept of combining voices in harmony to enrich plainsong chant was not new, there lacked the established and codified musical theory techniques to enable the rational construction of such pieces.

The Magnus Liber represents a step in the development of Western music between plainchant and the intricate polyphony of the later thirteenth and fourteenth centuries (see Machaut and Ars Nova). The music of the Magnus Liber displays a connection to the emerging Gothic style of architecture; just as ornate cathedrals were built to house holy relics, organa were written to elaborate Gregorian chant, which too was considered holy.

The innovations at Notre Dame consisted of a system of musical notation which included patterns of short and long musical notes known as longs and breves. [10] This system is referred to as mensural music as it demonstrates the beginning of "measured time" in music, organizing lengths of pitches within plainchant and later, the motet genre. In the organi of the Magnus Liber, one voice sang the notes of the Gregorian chant elongated to enormous length called the tenor (from Latin 'to hold'), but was also known as the vox principalis. As many as three voices, known as the vox organalis (or vinnola vox, the "vining voice") were notated above the tenor, with quicker lines moving and weaving together, a style also known as florid organum. [11] The development from a single line of music (monophony) to one where multiple lines all carried the same weight (polyphony) is shown through the writing of organa. The practice of keeping a slow moving "tenor" line continued into secular music, and the words of the original chant survived in some cases as well. One of the most common genres in the Magnus Liber is the clausula, which are "sections where, in discant style, the tenor uses rhythmic patterns as well as the upper part". [5] These sections of polyphony were substituted into longer organa. The extant manuscripts provide a number of notational challenges for modern editors since they contain only the polyphonic sections to which the monophonic chant must be added.

Medieval music encompasses the sacred and secular music of Western Europe during the Middle Ages, from approximately the 6th to 15th centuries. It is the first and longest major era of Western classical music and is followed by the Renaissance music; the two eras comprise what musicologists generally term as early music, preceding the common practice period. Following the traditional division of the Middle Ages, medieval music can be divided into Early (500–1000), High (1000–1300), and Late (1300–1400) medieval music.

Plainsong or plainchant is a body of chants used in the liturgies of the Western Church. When referring to the term plainsong, it is those sacred pieces that are composed in Latin text. Plainsong was the exclusive form of Christian church music until the ninth century, and the introduction of polyphony.

<span class="mw-page-title-main">Monophony</span> Musical texture

In music, monophony is the simplest of musical textures, consisting of a melody, typically sung by a single singer or played by a single instrument player without accompanying harmony or chords. Many folk songs and traditional songs are monophonic. A melody is also considered to be monophonic if a group of singers sings the same melody together at the unison or with the same melody notes duplicated at the octave. If an entire melody is played by two or more instruments or sung by a choir with a fixed interval, such as a perfect fifth, it is also said to be monophony. The musical texture of a song or musical piece is determined by assessing whether varying components are used, such as an accompaniment part or polyphonic melody lines.

Adam of Saint Victor was a prolific poet and composer of Latin hymns and sequences. He has been called "...the most illustrious exponent of the revival of liturgical poetry which the twelfth century affords."

Pérotin was a composer associated with the Notre Dame school of polyphony in Paris and the broader ars antiqua musical style of high medieval music. He is credited with developing the polyphonic practices of his predecessor Léonin, with the introduction of three and four-part harmonies.

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.

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.

<i>Ars antiqua</i> Musical style of the High Middle Ages

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. Although colloquially the term ars antiqua is used more loosely to mean all European music of the 13th century, and from slightly before.

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.

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 de Paris, most likely in the 1270s or 1280s. Nothing is known about his life. His writings survive in two partial copies from Bury St Edmunds; one from the 13th century, and one from the 14th.

The clausula was a newly composed section of discant inserted into a pre-existing setting of organum. Clausulae flourished in the late twelfth and thirteenth centuries and were associated with the Notre Dame school. The origin of the clausula has long been subject of scholarly debate, as the relationship between clausulae and motets is very complicated. 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.

<i>Conductus</i> Sacred Latin song in the Middle Ages

The conductus was a sacred Latin song in the Middle Ages, one whose poetry and music were newly composed. It is non-liturgical since its Latin lyric borrows little from previous chants. The conductus was northern French equivalent of the versus, which flourished in Aquitaine. It was originally found in the twelfth-century Aquitanian repertories. But major collections of conducti were preserved in Paris. The conductus typically includes one, two, or three voices. A small number of the conducti are for four voices. Stylistically, the conductus is a type of discant. Its form can be strophic or through-composed form. The genre flourished from the early twelfth century to the middle of thirteenth century. It was one of the principal types of vocal composition of the ars antiqua period of medieval music history.

<span class="mw-page-title-main">Rhythmic mode</span>

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.

A descant, discant, or discantus is any of several different things in music, depending on the period in question; etymologically, the word means a voice (cantus) above or removed from others. The Harvard Dictionary of Music states:

Anglicized form of L. discantus and a variant of discant. Throughout the Middle Ages the term was used indiscriminately with other terms, such as descant. In the 17th century it took on special connotations in instrumental practice.

France has a rich music history that was already prominent in Europe as far back as the 10th century. French music originated as a unified style in medieval times, focusing around the Notre-Dame school of composers. This group developed the motet, a specific musical composition. Notable in the high Middle Ages were the troubadours and trouvères soon began touring France, composing and performing many original songs. The styles of ars nova and ars subtilior sprung up in the 14th century, both of which focused on secular songs. As Europe moved into the Renaissance age, the music of France evolved in sophistication. The popularity of French music in the rest of Europe declined slightly, yet the popular chanson and the old motet were further developed during this time. The epicenter of French music moved from Paris to Burgundy, as it followed the Burgundian School of composers. During the Baroque period, music was simplified and restricted due to Calvinist influence. The air de cour then became the primary style of French music, as it was secular and preferred by the royal court.

<span class="mw-page-title-main">Winchester Troper</span> English music manuscript, dated c. 1000

The Winchester Troper refers to two eleventh-century manuscripts of liturgical plainchant and two-voice polyphony copied and used in the Old Minster at Winchester Cathedral in Hampshire, England. The manuscripts are now held at Cambridge, Corpus Christi College 473 and Oxford, Bodleian Library Bodley 775 . The term "Winchester Troper" is best understood as the repertory of music contained in the two manuscripts. Both manuscripts contain a variety of liturgical genres, including Proper and Ordinary chants for both the Mass and the Divine Office. Many of the chants can also be found in other English and Northern French tropers, graduals, and antiphoners. However, some chants are unique to Winchester, including those for local saints such as St. Æthelwold and St. Swithun, who were influential Bishops of Winchester in the previous centuries. Corpus 473 contains the most significant and largest surviving collection of eleventh-century organum. This polyphonic repertoire is unique to that manuscript.

Benedicamus Domino is a closing salutation that was formerly used in the Latin 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 Saint Martial School was a medieval school of music composition centered in the Abbey of Saint Martial, Limoges, France. Most active from the 9th to 12th centuries, some scholars describe its practices, music, and manuscripts as 'Aquitanian'. It is known for the composition of tropes, sequences, and early organum. In this respect, it was an important precursor to the Notre Dame School. Adémar de Chabannes and his nephew Roger de Chabannes were important proponents of this school whose hands had only be recently discovered by studies of James Grier between 1995 and 2005. They invented a local variant of a vertically precise organisation of notation and a new form of local tonary, they reorganised existing chant manuscripts, and they developed the libellum structure of a new type of sequentiary troper whose organisation was new at their time, but played a key role for the Saint Martial school.

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."

"Viderunt omnes" is a Gregorian chant based on Psalm XCVII (98), sung as the gradual at the Masses of Christmas Day and historically on its octave, the Feast of the Circumcision. Two of the many settings of the text are famous as being among the earliest pieces of polyphony by known composers, Léonin and Pérotin of the Notre Dame school. Their music, known as organum, adds florid counterpoint to the Gregorian melody of the intonation and verse, portions normally sung by the cantors, the remainder of the chant being sung unchanged by the choir.
