The Micrologus is a treatise on Medieval music written by Guido of Arezzo , dating to approximately 1026. It was dedicated to Tedald, Bishop of Arezzo . This treatise outlines singing and teaching practice for Gregorian chant , and has considerable discussion of the composition of polyphonic music.
125-397: This treatise discusses modified parallel organum as well as free organum. The examples given are in two voices, set note-against-note, and the voices are frequently permitted to cross . He advised against use of the perfect fifth and minor second , favouring instead the major second and perfect fourth (though thirds were also permitted). One point of importance is his guideline for
250-463: 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 (or bourdon ) may be sung on the same text, the melody may be followed in parallel motion (parallel organum ), or a combination of both of these techniques may be employed. As no real independent second voice exists, this
375-408: A bridge section between modal and non-modal sections. It seems that for most instances we can take Garlandia literally where he says 'between' organum and discant. In organa dupla, the copula is very similar to a short, cadential organum purum section but in organa tripla or conducti it is seen that irregular notation is used. Either the last notes of ligatures are affixed with a plica which divides
500-512: A complex system expressed by cheironomic hand-gestures. This approach prevailed during the twentieth century, propagated by Justine Ward 's program of music education for children, until the liturgical role of chant was diminished after the liturgical reforms of Pope Paul VI , and new scholarship "essentially discredited" Mocquereau's rhythmic theories. Common modern practice favors performing Gregorian chant with no beat or regular metric accent, largely for aesthetic reasons. The text determines
625-444: A decorated leap from G to C to establish this tonality. Similar examples exist throughout the repertory. The earliest notated sources of Gregorian chant (written c. 950 ) used symbols called neumes (Gr. sign, of the hand) to indicate tone-movements and relative duration within each syllable. A sort of musical stenography that seems to focus on gestures and tone-movements but not the specific pitches of individual notes, nor
750-517: A definite pattern. The Notre-Dame composers' development of musical rhythm allowed music to be free from its ties to text. While it is well known that Léonin composed a great deal of organum , it was the innovations of Pérotin, who spent much of his time revising the organum purum of Léonin, that caused generations of organum and motet composers to exploit the principles of the rhythmic modes. Cultural and intellectual life flourished in Paris during
875-431: A florid cadence over a sustained tenor. Thus, in larger texts, depending on how the words were set to music, syllabic parts (having no ligatures and therefore non-modal) end up as organum purum : the tenor sustains each single note of the chant over which the organal voice drapes a new florid line, written mostly in ligatures and compound neumes. Starting from a consonant, mostly the octave, sometimes lead in by 7–8 over 1,
1000-529: A form of monophonic , unaccompanied sacred song in Latin (and occasionally Greek ) of the Roman Catholic Church . Gregorian chant developed mainly in western and central Europe during the 9th and 10th centuries, with later additions and redactions. Although popular legend credits Pope Gregory I with inventing Gregorian chant, scholars believe that it arose from a later Carolingian synthesis of
1125-643: A four-line staff with a clef, as in the Graduale Aboense pictured above. In square notation, small groups of ascending notes on a syllable are shown as stacked squares, read from bottom to top, while descending notes are written with diamonds read from left to right. When a syllable has a large number of notes, a series of smaller such groups of neumes are written in succession, read from left to right. The oriscus , quilisma , and liquescent neumes indicate special vocal treatments, that have been largely neglected due to uncertainty as to how to sing them. Since
1250-407: A free rhythm of equal note values, although some notes are lengthened for textual emphasis or musical effect. The modern Solesmes editions of Gregorian chant follow this interpretation. Mocquereau divided melodies into two- and three-note phrases, each beginning with an ictus , akin to a beat, notated in chantbooks as a small vertical mark. These basic melodic units combined into larger phrases through
1375-413: A good example of the principles used. "Benedicamus" is usually mixed syllabic— neumatic in that it has mostly one note or maybe two per syllable of text, which is set in florid organum over a sustained tenor. "Domino" is in its Gregorian form set in melismatic style with three or more notes to a syllable and here both tenor and duplum proceed in discantus set in the six rhythmic modes, to be finalized with

Pérotin "is the best composer of discantus", according to Anonymous IV, an English student, writing ca.1275, who has provided at least a few morsels of factual information on Paris Organum and its composers. Pérotin further developed discantus in three part Organum (Organum Triplum) where both organal voices are in discantus. Note that organum purum
1625-473: A practice called centonization . Tracts are melismatic settings of psalm verses and use frequent recurring cadences and they are strongly centonized. Gregorian chant evolved to fulfill various functions in the Roman Catholic liturgy. Broadly speaking, liturgical recitatives are used for texts intoned by deacons or priests. Antiphonal chants accompany liturgical actions: the entrance of the officiant,
1750-420: A remarkably uniform state across Europe within a short time. Charlemagne , once elevated to Holy Roman Emperor , aggressively spread Gregorian chant throughout his empire to consolidate religious and secular power, requiring the clergy to use the new repertory on pain of death. From English and German sources, Gregorian chant spread north to Scandinavia , Iceland and Finland . In 885, Pope Stephen V banned
1875-418: A renowned monastic reformer, praised the intellectual and musical virtuosity to be found in chant: For in these [Offertories and Communions] there are the most varied kinds of ascent, descent, repeat..., delight for the cognoscenti , difficulty for the beginners, and an admirable organization... that widely differs from other chants; they are not so much made according to the rules of music... but rather evince
2000-534: A seventh than a full octave, so that melodies rarely travel from D up to the D an octave higher, but often travel from D to the C a seventh higher, using such patterns as D-F-G-A-C. > Gregorian melodies often explore chains of pitches, such as F-A-C, around which the other notes of the chant gravitate. Within each mode, certain incipits and cadences are preferred, which the modal theory alone does not explain. Chants often display complex internal structures that combine and repeat musical subphrases. This occurs notably in
2125-508: A single compound neume, abound in the text. Melismatic chants are the most ornate chants in which elaborate melodies are sung on long sustained vowels as in the Alleluia, ranging from five or six notes per syllable to over sixty in the more prolix melismata. Gregorian chants fall into two broad categories of melody: recitatives and free melodies. The simplest kind of melody is the liturgical recitative. Recitative melodies are dominated by
2250-461: A single pitch, called the reciting tone . Other pitches appear in melodic formulae for incipits , partial cadences , and full cadences. These chants are primarily syllabic. For example, the Collect for Easter consists of 127 syllables sung to 131 pitches, with 108 of these pitches being the reciting note A and the other 23 pitches flexing down to G. Liturgical recitatives are commonly found in
2375-476: A tetrachord that corresponds to the four finals of chant, D, E, F, and G. The disjunct tetrachords in the Enchiriadis system have been the subject of much speculation, because they do not correspond to the diatonic framework that became the standard Medieval scale (for example, there is a high F ♯ , a note not recognized by later Medieval writers). A diatonic scale with a chromatically alterable b/b-flat
2500-403: A warbling of pitches between the notes E and F, outside the hexachord system, or in other words, employing a form of chromaticism . Early Gregorian chant, like Ambrosian and Old Roman chant, whose melodies are most closely related to Gregorian, did not use the modal system. The great need for a system of organizing chants lies in the need to link antiphons with standard tones, as in for example,
2625-442: 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

Pérotin even went as far as composing two four-part organa (quadrupla), "Viderunt omnes" and "Sederunt principes" which were performed in Notre-Dame in 1198 on New Year's Day and in 1199 on the feast of St Stephen (a decree of Odon de Sully , Bishop of Paris, exists which stipulates

Organum duplum in its organum purum sections of syllabic setting, the cum littera sections in two-part conductus, copulae in general and monophonic conductus would be that part of the repertory which is not strictly modal.

At c. 520, Benedict of Nursia established what is called the rule of St. Benedict, in which the protocol of the Divine Office for monastic use was laid down. Around 678, Roman chant was taught at York . Distinctive regional traditions of Western plainchant arose during this period, notably in
3250-425: Is sometimes called parallel organum , although terms such as sinfonia or diaphonia were used in early treatises. The history of organum would not be complete without two of its greatest innovators, Léonin and Pérotin . These two men were "the first international composers of polyphonic music". The innovations of Léonin and Pérotin mark the development of the rhythmic modes. These innovations are grounded in
3375-438: Is the sequence, whose origins lay in troping the extended melisma of Alleluia chants known as the jubilus , but the sequences, like the tropes, were later officially suppressed. The Council of Trent struck sequences from the Gregorian corpus, except those for Easter , Pentecost , Corpus Christi and All Souls' Day . Not much is known about the particular vocal stylings or performance practices used for Gregorian chant in
3500-512: The Introit , and Communion originally referred to chants in which two choirs sang in alternation, one choir singing verses of a psalm, the other singing a refrain called an antiphon . Over time, the verses were reduced in number, usually to just one psalm verse and the doxology , or even omitted entirely. Antiphonal chants reflect their ancient origins as elaborate recitatives through the reciting tones in their melodies. Ordinary chants, such as
3625-624: The Kyrie and Gloria , are not considered antiphonal chants, although they are often performed in antiphonal style. Responsorial chants such as the Gradual , Alleluia , Offertory , and the Office Responsories originally consisted of a refrain called a respond sung by a choir, alternating with psalm verses sung by a soloist. Responsorial chants are often composed of an amalgamation of various stock musical phrases, pieced together in
3750-634: The Offertories ; in chants with shorter, repeating texts such as the Kyrie and Agnus Dei ; and in longer chants with clear textual divisions such as the Great Responsories, the Gloria , and the Credo . Chants sometimes fall into melodically related groups. The musical phrases centonized to create Graduals and Tracts follow a musical "grammar" of sorts. Certain phrases are used only at

Mozarabic chant survived the influx of the Visigoths and Moors , but not the Roman-backed prelates newly installed in Spain during the Reconquista . Restricted to a handful of dedicated chapels, modern Mozarabic chant is highly Gregorianized and bears no musical resemblance to its original form. Ambrosian chant alone survived to

The other plainchant repertories of the Christian West faced severe competition from the new Gregorian chant.

By the 9th century the Gallican rite and chant had effectively been eliminated, although not without local resistance. The Gregorian chant of

Psalmodic chants, which intone psalms , include both recitatives and free melodies. Psalmodic chants include direct psalmody , antiphonal chants , and responsorial chants . In direct psalmody, psalm verses are sung without refrains to simple, formulaic tones. Most psalmodic chants are antiphonal and responsorial, sung to free melodies of varying complexity. Antiphonal chants such as

Later adaptations and innovations included the use of a dry-scratched line or an inked line or two lines, marked C or F showing the relative pitches between neumes. Consistent relative heightening first developed in the Aquitaine region, particularly at St. Martial de Limoges , in the first half of the eleventh century. Many German-speaking areas, however, continued to use unpitched neumes into

Reinforced by the legend of Pope Gregory, Gregorian chant was taken to be the authentic, original chant of Rome, a misconception that continues to this day. By the 12th and 13th centuries, Gregorian chant had supplanted or marginalized all the other Western plainchant traditions. Later sources of these other chant traditions show an increasing Gregorian influence, such as occasional efforts to categorize their chants into

He reorganized

Vatican II officially allowed worshipers to substitute other music, particularly sacred polyphony, in place of Gregorian chant, although it did reaffirm that Gregorian chant was still the official music of the Roman Rite of the Catholic Church, and the music most suitable for worship in the Roman Liturgy. Gregorian chant is, as 'chant' implies, vocal music. The text,
5500-895: The Christian liturgy since the earliest days of the Church. It is widely accepted that the psalmody of ancient Jewish worship significantly influenced and contributed to early Christian ritual and chant. Christians read Scriptures and sang chants, as their Jewish predecessors had done. Although new Christian liturgy was developed, the source of much of this Christian liturgy was Jewish psalmody. The source materials for newly emergent Christian chants were originally transmitted by Jews in sung form. Early Christian rites also incorporated elements of Jewish worship that survived in later chant tradition. Canonical hours have their roots in Jewish prayer hours. " Amen " and " alleluia " come from Hebrew , and
5625-501: The Communion Circuibo was transcribed using a different mode in each. Several features besides modality contribute to the musical idiom of Gregorian chant, giving it a distinctive musical flavor. Melodic motion is primarily stepwise . Skips of a third are common, and larger skips far more common than in other plainchant repertories such as Ambrosian chant or Beneventan chant. Gregorian melodies are more likely to traverse
5750-536: The Gregorian modes . Similarly, the Gregorian repertory incorporated elements of these lost plainchant traditions, which can be identified by careful stylistic and historical analysis. For example, the Improperia of Good Friday are believed to be a remnant of the Gallican repertory. The first extant sources with musical notation were written around 930 (Graduale Laon). Before this, plainchant had been transmitted orally. Most scholars of Gregorian chant agree that
5875-572: The Middle Ages. On occasion, the clergy was urged to have their singers perform with more restraint and piety. This suggests that virtuosic performances occurred, contrary to the modern stereotype of Gregorian chant as slow-moving mood music. This tension between musicality and piety goes far back; Gregory the Great himself criticized the practice of promoting clerics based on their charming singing rather than their preaching. However, Odo of Cluny ,

The Apostolic Tradition , attributed to the theologian Hippolytus , attests the singing of Hallel (Jewish) psalms with Alleluia as the refrain in early Christian agape feasts . Chants of the Office, sung during the canonical hours, have their roots in the early 4th century, when desert monks following St. Anthony introduced the practice of continuous psalmody, singing

Of those, he retained what he could, revised where necessary, and assigned particular chants to the various services. According to Donald Jay Grout , his goal was to organize the bodies of chants from diverse traditions into a uniform and orderly whole for use by
6250-572: The Solesmes chant – now compiled as the Liber usualis – as authoritative. In 1904, the Vatican edition of the Solesmes chant was commissioned. Serious academic debates arose, primarily owing to stylistic liberties taken by the Solesmes editors to impose their controversial interpretation of rhythm. The Solesmes editions insert phrasing marks and note-lengthening episema and mora marks not found in
6375-490: The academically sound 'Paleo' was intended to be a war-tank, meant to abolish once and for all the corrupted Pustet edition. On the evidence of congruence throughout various manuscripts (which were duly published in facsimile editions with ample editorial introductions) Solesmes was able to work out a practical reconstruction. This reconstructed chant was academically praised, but rejected by Rome until 1903, when Pope Leo XIII died. His successor, Pope Pius X , promptly accepted

Cardine shows

However, antiphonal chants are generally performed in responsorial style by a solo cantor alternating with a chorus. This practice appears to have begun in the Middle Ages. Another medieval innovation had the solo cantor sing the opening words of responsorial chants, with
6750-486: The b-mollum. This system of square notation is standard in modern chantbooks. Gregorian chant was originally used for singing the Office (by male and female religious) and for singing the parts of the Mass pertaining to the lay faithful (male and female), the celebrant (priest, always male) and the choir (composed of male ordained clergy, except in convents). Outside the larger cities, the number of available clergy dropped, and lay men started singing these parts. The choir

Several Introits in mode 3, including Loquetur Dominus above, exhibit melodic similarities. Mode III (E authentic) chants have C as a dominant, so C is the expected reciting tone. These mode III Introits, however, use both G and C as reciting tones, and often begin with

The presence of Léonin and Pérotin at the Notre-Dame School made Paris the centre of the musical world in the 12th century. Léonin, magister cantus of Notre-Dame, compiled the Magnus Liber Organi de Gradali et Antiphonario . Léonin wrote organa dupla based on existing chants like the Alleluia and

Thus we find models for the recitation of psalmverses, Alleluia and Gloria Patri for all eight modes. Not every Gregorian chant fits neatly into Guido's hexachords or into the system of eight modes. For example, there are chants – especially from German sources – whose neumes suggest

The non-psalmodic chants, including the Ordinary of the Mass , sequences , and hymns , were originally intended for congregational singing. The structure of their texts largely defines their musical style. In sequences, the same melodic phrase is repeated in each couplet. The strophic texts of hymns use

The third form is copula (Lat. coming together) which in the words of Johannes de Garlandia "is between organum and discant". and according to Waite

The earlier notated manuscripts are primarily from Regensburg in Germany, St. Gall in Switzerland, Laon and St. Martial in France. Gregorian chant has in its long history been subjected to a series of redactions to bring it up to changing contemporary tastes and practice. The more recent redaction undertaken in

This section of discantus is concluded, on the last syllable of a word or phrase, by a copula, in which
8125-459: The earliest manuscripts pose difficulties on the interpretation of rhythm. Certain neumes such as the pressus , pes quassus, strophic neumes may indicate repeated notes, lengthening by repercussion, in some cases with added ornaments. By the 13th century, with the widespread use of square notation, most chant was sung with an approximately equal duration allotted to each note, although Jerome of Moravia cites exceptions in which certain notes, such as

His renowned love for music was recorded only 34 years after his death; the epitaph of Honorius testified that comparison to Gregory was already considered the highest praise for a music-loving pope. While later legends magnified his real achievements, these significant steps may account for why his name came to be attached to Gregorian chant. The Gregorian repertory
8500-415: The final notes of a chant, are lengthened. While the standard repertory of Gregorian Chant was partly being supplanted by new forms of polyphony, the earlier melo-rhythmic refinements of monophonic chant seem to have fallen into disuse. Later redactions such as the Editio medicaea of 1614 rewrote chant so that melismata, with their melodic accent, fell on accented syllables. This aesthetic held sway until

It is the composers' love for cantus firmus that caused the notation of the tenor line to stay the same, even when the methods of penning music were changing. It was the use of modal rhythm , however, that would make these two men great. Modal rhythm is defined clearly as a succession of (usually) unequal notes arranged in

9000-472: The interpretation of the music should always be according to modal or Franconian principles. Willi Apel and William G. Waite insisted upon a rigorously modal interpretation. Though Waite in his dissertation, notably in chapter 4: The notation of organum duplum' acknowledged that in organum duplum and monophonic conducts relative freedom may have been taken, he transcribed a selection of the Magnus Liber Organi of Léonin into strict modal rhythm. Apel argued that

9500-420: The long values for dissonances (in violation of the basic principle of consonance) produced by modal rhythms in Notre-Dame organa, can be reconciled by a statement made by several medieval theorists that "the tenor pauses, if a dissonance appears". Debates on interpretation are ongoing. However, Waite was working in the 1950s, and his point of view has been supplanted by newer research: "...but [Waite's] view that
9625-469: The main wells of information concerning its history come from Gregorian chant . Considering that the trained singers had imbibed an oral tradition that was several centuries old, singing a small part of the chant repertory in straightforward heterophony of parallel harmony or other ways of "singing by the ear" would come naturally. It is made clear in the Musica enchiriadis that octave doubling (magadization)
9750-490: The melody revolve, and a vocabulary of musical motifs woven together through a process called centonization to create families of related chants. The scale patterns are organized against a background pattern formed of conjunct and disjunct tetrachords , producing a larger pitch system called the gamut . The chants can be sung by using six- note patterns called hexachords . Gregorian melodies are traditionally written using neumes , an early form of musical notation from which
9875-464: The modern four-line and five-line staff developed. Multi-voice elaborations of Gregorian chant, known as organum , were an early stage in the development of Western polyphony . Gregorian chant was traditionally sung by choirs of men and boys in churches, or by women and men of religious orders in their chapels. It is the music of the Roman Rite , performed in the Mass and the monastic Office . Although Gregorian chant supplanted or marginalized
10000-464: The modes with melodies ending on A, B, and C are sometimes referred to as Aeolian , Locrian , and Ionian , these are not considered distinct modes and are treated as transpositions of whichever mode uses the same set of hexachords. The actual pitch of the Gregorian chant is not fixed, so the piece can be sung in whichever range is most comfortable. Certain classes of Gregorian chant have a separate musical formula for each mode, allowing one section of
10125-582: The modes, rarely used in medieval times, derive from a misunderstanding of the Ancient Greek modes; the prefix " hypo- " (under, Gr.) indicates a plagal mode, where the melody moves below the final. In contemporary Latin manuscripts the modes are simply called Protus authentus /plagalis, Deuterus, Tritus and Tetrardus: the 1st mode, authentic or plagal, the 2nd mode etc. In the Roman Chantbooks the modes are indicated by Roman numerals. Although
10250-479: The monastic tradition in Solesmes. Re-establishing the Divine Office was among his priorities, but no proper chantbooks existed. Many monks were sent out to libraries throughout Europe to find relevant Chant manuscripts. In 1871, however, the old Medicea edition was reprinted ( Pustet , Regensburg) which Pope Pius IX declared the only official version. In their firm belief that they were on the right way, Solesmes increased its efforts. In 1889, after decades of research,
10375-513: The monks of Solesmes released the first book in a planned series, the Paléographie Musicale. The incentive of its publication was to demonstrate the corruption of the 'Medicea' by presenting photographed notations originating from a great variety of manuscripts of one single chant, which Solesmes called forth as witnesses to assert their own reforms. The monks of Solesmes brought in their heaviest artillery in this battle, as indeed
10500-489: The new system of chants were so significant that they have led some scholars to speculate that it was named in honor of the contemporary Pope Gregory II . Nevertheless, the lore surrounding Pope Gregory I was sufficient to culminate in his portrayal as the actual author of Gregorian Chant. He was often depicted as receiving the dictation of plainchant from a dove representing the Holy Spirit , thus giving Gregorian chant
10625-417: The newly consecrated cathedrals resounded with ever more complex forms of polyphony. Exactly what developments took place where and when in the evolution of polyphony is not always clear, though some landmarks remain visible in the treatises. As in these instances, it is hard to evaluate the relative importance of treatises, whether they describe the 'actual' practice or a deviation of it. As key-concept behind
10750-483: The newly understood principles in performance practice. The studies of Cardine and his students (Godehard Joppich, Luigi Augustoni, Johannes B. Göschl, Marie-Noël Colette, Rupert Fischer, Marie-Claire Billecocq, Alexander M. Schweitzer to name a few) have clearly demonstrated that rhythm in Gregorian chant as notated in the 10th century rhythmic manuscripts (notably Sankt Gallen and Laon) manifest such rhythmic diversity and melodic – rhythmic ornamentations for which there
10875-401: The notes in smaller values, or a series of disjunct rests is used in jolting succession in both parts, creating what is also called hocket . These features also can be frequently found in two-part discantus on special cadences or a preparation of a cadence, where they are also referred to as "copulae". Garlandia states simply: "a copula is where are any number of lines are found". referring to
11000-492: The onset of the Solesmes restoration is substantially at odds with musicological evidence. In his motu proprio Tra le sollecitudini , Pius X mandated the use of Gregorian chant, encouraging the faithful to sing the Ordinary of the Mass , although he reserved the singing of the Propers for males. While this custom is maintained in traditionalist Catholic communities (most of which allow all-female scholas as well, though),
11125-412: The original sources. Conversely, they omit significative letters found in the original sources, which give instructions for rhythm and articulation such as speeding up or slowing down. These editorial practices have placed the historical authenticity of the Solesmes interpretation in doubt. Ever since restoration of Chant was taken up in Solesmes, there have been lengthy discussions of exactly what course
11250-616: The other indigenous plainchant traditions of the Christian West to become the official music of the Christian liturgy, Ambrosian chant still continues in use in Milan, and there are musicologists exploring both that and the Mozarabic chant of Christian Spain. Although Gregorian chant is no longer obligatory, the Roman Catholic Church still officially considers it the music most suitable for worship. Singing has been part of
11375-655: The performance of 'organa tripla vel quadrupla') Apart from organa, Pérotin extended the form of the Aquitanian versus which was henceforth called conductus . Any conductus is a new composition on new texts and is always composed in the rhythmic modes. Perotin set several texts by Philippe le Chancelier, while some texts refer to contemporary events. Two-part conductus form the larger part, though conductus exist for one to four voices. Three and four part conductus are, by necessity, composed throughout in discantus style. As in organa tripla, handling three voices (or four) precludes
11500-429: The phrases, words and eventually the syllables, can be sung in various ways. The most straightforward is recitation on the same tone, which is called "syllabic" as each syllable is sung to a single tone. Likewise, simple chants are often syllabic throughout with only a few instances where two or more notes are sung on one syllable. "Neumatic" chants are more embellished and ligatures , a connected group of notes, written as
11625-598: The plicae or rest-signs. Thus organum duplum on a texted chant as a gradual, responsory or the verse of an Alleluia can be schematized as follows: In the Notre-Dame repertory the Alleluia itself is only composed organaliter in the opening section, before the Jubilus , the protracted vocalization of the last syllable, which is to be sung choraliter, and as such is absent from all extant original manuscripts. The above stated general principles have been used freely, as in Alleluia V. Dies sanctificatus , where "dies" starts off with
11750-487: The practical art of cantus. The earliest writings that deal with both theory and practice include the Enchiriadis group of treatises, which circulated in the late ninth century and possibly have their roots in an earlier, oral tradition. In contrast to the ancient Greek system of tetrachords (a collection of four continuous notes) that descend by two tones and a semitone, the Enchiriadis writings base their tone-system on
11875-506: The present day, preserved in Milan due to the musical reputation and ecclesiastical authority of St. Ambrose . Gregorian chant eventually replaced the local chant tradition of Rome itself, which is now known as Old Roman chant. In the 10th century, virtually no musical manuscripts were being notated in Italy. Instead, Roman Popes imported Gregorian chant from (German) Holy Roman Emperors during
12000-522: The prosulae that were composed, replacing a long melisma in a chant with new, additional words. This would have been the first instance of two different texts being sung in harmony. In turn, the motellus gave birth to the motet which is a poly-textual piece in discant, which obviously sparked a lot a creativity as it soon became a prolific form of composition. The organa that were created in Paris were disseminated throughout Europe. The three main sources are W1, St. Andrews, Wolfenbüttel 677, olim Helmstedt 628;
12125-736: The psalmody at the Office. Using Psalm Tone i with an antiphon in Mode 1 makes for a smooth transition between the end of the antiphon and the intonation of the tone, and the ending of the tone can then be chosen to provide a smooth transition back to the antiphon. As the modal system gained acceptance, Gregorian chants were edited to conform to the modes, especially during 12th-century Cistercian reforms. Finals were altered, melodic ranges reduced, melismata trimmed, B-flats eliminated, and repeated words removed. Despite these attempts to impose modal consistency, some chants – notably Communions – defy simple modal assignment. For example, in four medieval manuscripts,
12250-436: The range of pitches used in the melody. Melodies whose final is in the middle of the ambitus, or which have only a limited ambitus, are categorized as plagal , while melodies whose final is in the lower end of the ambitus and have a range of over five or six notes are categorized as authentic . Although corresponding plagal and authentic modes have the same final, they have different dominants. The existent pseudo-Greek names of
12375-406: The re-examination of chant in the late 19th century by such scholars as Peter Wagner [ de ] , Pothier , and Mocquereau , who fell into two camps. One school of thought, including Wagner, Jammers, and Lipphardt, advocated imposing rhythmic meters on chants, although they disagreed on how that should be done. An opposing interpretation, represented by Pothier and Mocquereau, supported
12500-466: The relative starting pitches of each neume. Given the fact that Chant was learned in an oral tradition in which the texts and melodies were sung from memory, this was obviously not necessary. The neumatic manuscripts display great sophistication and precision in notation and a wealth of graphic signs to indicate the musical gesture and proper pronunciation of the text. Scholars postulate that this practice may have been derived from cheironomic hand-gestures,
12625-449: The reverse process at the end. Organum was originally improvised ; while one singer performed a notated melody (the vox principalis ), another singer—singing "by ear"—provided the unnotated second melody (the vox organalis ). Over time, composers began to write added parts that were not just simple transpositions, thus creating true polyphony . The first document to describe organum specifically, and give rules for its performance,
12750-457: The same clausulae (Domino, et gaudebit in variant settings, according to. 'written in a variety of styles and with varying competence' A further innovation was the motellus , to be found in W2, in which the upper part of a discant section is supplied with a new text, so that when the tenor utters a single syllable of chant, the upper part will pronounce several syllables or words. As such it reminds of
12875-445: The same melodic phrases in a melismatic chant (repeating an entire Alleluia-melody on a new text for instance, or repeating a full phrase with a new text that comments on the previously sung text) and various forms of organum , (improvised) harmonic embellishment of chant melodies focusing on octaves, fifths, fourths, and, later, thirds. Neither tropes nor organum, however, belong to the chant repertory proper. The main exception to this
13000-418: The same syllabic melody for each stanza. Early plainchant, like much of Western music, is believed to have been distinguished by the use of the diatonic scale . Modal theory, which postdates the composition of the core chant repertory, arises from a synthesis of two very different traditions: the speculative tradition of numerical ratios and species inherited from ancient Greece and a second tradition rooted in
13125-433: The shape of a remembered melody. This notation was further developed over time, culminating in the introduction of staff lines (attributed to Guido d'Arezzo ) in the early 11th century, what we know today as plainchant notation. The whole body of Frankish-Roman Carolingian chant, augmented with new chants to complete the liturgical year, coalesced into a single body of chant that was called "Gregorian." The changes made in
13250-439: The singing range were organized into overlapping hexachords . Hexachords could be built on C (the natural hexachord, C-D-E^F-G-A), F (the soft hexachord, using a B-flat, F-G-A^B ♭ -C-D), or G (the hard hexachord, using a B-natural, G-A-B^C-D-E). The B-flat was an integral part of the system of hexachords rather than an accidental . The use of notes outside of this collection was described as musica ficta . Gregorian chant
13375-456: The stamp of being divinely inspired. Scholars agree that the melodic content of much Gregorian Chant did not exist in that form in Gregory I's day. In addition, it is known definitively that the familiar neumatic system for notating plainchant had not been established in his time. Nevertheless, Gregory's authorship is popularly accepted by some as fact to this day. Gregorian chant appeared in
13500-417: The synthesized chant repertory. There were other developments as well. Chants were modified, influenced by local styles and Gallican chant, and fitted into the theory of the ancient Greek octoechos system of modes in a manner that created what later came to be known as the western system of the eight church modes . The Metz project also invented an innovative musical notation , using freeform neumes to show
13625-461: The tenor in organa dupla in discant sections proceeds always in the 5th mode (all longs in a rhythmic group ordine), Pérotin, who was a generation removed from Léonin, saw fit to improve them by introducing different modes for the tenor and new melodic lines for the dupla, increasing the rhythmic organization and diversity of the section. However, in the largest compilation of Notre-Dame repertoires (F) no less than 462 clausulae exist, many recurrences of
13750-410: The tenor sustains either the penultimate or the last tone and the duplum switches back to a florid cadence, to conclude on a consonance. Thus, in organum duplum of Léonin these compositional idioms alternate throughout the complete polyphonic setting, which is concluded in monophonic chant for the last phrase. Thus, three different styles in the organaliter section are alternated and linked according to
13875-503: The text, leaving the last part of the text to be sung choraliter in monophonic chant. The verse of the chant is worked out according to the same principles. The relevant contemporary authors who write about the organum of the Notre-Dame school, Anonymous IV , Johannes de Garlandia , the St. Emmeram Anonymous and Franco of Cologne , to name a few, are not always as clear as could be desired. Nevertheless, much information can be distilled from
14000-673: The threefold " sanctus " derives from the threefold "kadosh" of the Kedushah . The New Testament mentions singing hymns during the Last Supper : "When they had sung the hymn, they went out to the Mount of Olives " ( Matthew 26.30 ). Other ancient witnesses such as Pope Clement I , Tertullian , St. Athanasius , and Egeria confirm the practice, although in poetic or obscure ways that shed little light on how music sounded during this period. Musical elements that would later be used in
14125-415: The time, going back to St. Augustine's De Musica . It has been firmly established by extensive research in chant traditions (Gregorian Semiology) that there is a fluency and variability in the rhythm of declamatory speech that should also govern chant performance. These principles extend to the not strictly modal sections or compositions, as a contrasting quality with musica mensurabilis. As Parisian Organum
14250-465: The twelfth century. Additional symbols developed, such as the custos , placed at the end of a system to show the next pitch. Other symbols indicated changes in articulation, duration, or tempo, such as a letter "t" to indicate a tenuto . Another form of early notation used a system of letters corresponding to different pitches, much as Shaker music is notated. By the 13th century, the neumes of Gregorian chant were usually written in square notation on
14375-416: The two most important manuscripts copied under and over the 4-line staff of the square notation. The Graduale Triplex made widely accessible the original notation of Sankt Gallen and Laon (compiled after 930 AD) in a single chantbook and was a huge step forward. Dom Cardine had many students who have each in their own way continued their semiological studies, some of whom also started experimenting in applying
14500-461: The use of the rhythmic modes as a creative principle. Thus, when in a discussion of organum of the Paris School the word "modal" or "mode" is used, it refers to the rhythmic modes and specifically not to the musical modes that rule over melody. In Léonin's Organa de Gradali et Antiphonario two forms of organum technique are evident: organum purum and discantus . Benedicamus Domino is
14625-481: Was acceptable, since such doubling was inevitable when men and boys sang together. The 9th-century treatise Scolica enchiriadis treats the subject in greater detail. For parallel singing, the original chant would be the upper voice, vox principalis ; the vox organalis was at a parallel perfect interval below, usually a fourth. Thus the melody would be heard as the principal voice, the vox organalis as an accompaniment or harmonic reinforcement. This kind of organum
14750-412: Was categorized into eight modes , influenced by the eightfold division of Byzantine chants called the oktoechos . Each mode is distinguished by its final , dominant , and ambitus . The final is the ending note, which is usually an important note in the overall structure of the melody. The dominant is a secondary pitch that usually serves as a reciting tone in the melody. Ambitus refers to
14875-465: Was considered an official liturgical duty reserved to clergy, so women were not allowed to sing in the Schola Cantorum or other choirs except in convents where women were permitted to sing the Office and the parts of the Mass pertaining to the choir as a function of their consecrated life. Chant was normally sung in unison. Later innovations included tropes , which is a new text sung to
15000-466: Was first described by Hucbald , who adopted the tetrachord of the finals (D, E, F, G) and constructed the rest of the system following the model of the Greek Greater and Lesser Perfect Systems. These were the first steps in forging a theoretical tradition that corresponded to chant. Around 1025, Guido d'Arezzo revolutionized Western music with the development of the gamut , in which pitches in
15125-417: Was further systematized for use in the Roman Rite , and scholars weigh the relative influences of Roman and Carolingian practices upon the development of plainchant. The late 8th century saw a steadily increasing influence of the Carolingian monarchs over the popes. During a visit to Gaul in 752–753, Pope Stephen II celebrated Mass using Roman chant. According to Charlemagne , his father Pepin abolished
15250-423: Was never intended as polyphony in the modern sense; the added voice was intended as a reinforcement or harmonic enhancement of the plainchant at occasions of High Feasts of importance to further the splendour of the liturgy . The analogue evolution of sacred architecture and music is evident: during previous centuries monophonic Mass was celebrated in abbatial churches; in the course of the 12th and 13th centuries
15375-635: Was perceived as corrupt and flawed "barbarism" by making the chants conform to contemporary aesthetic standards. In 1811, the French musicologist Alexandre-Étienne Choron , as part of a conservative backlash following the liberal Catholic orders' inefficacy during the French Revolution , called for returning to the "purer" Gregorian chant of Rome over French corruptions. In the late 19th century, early liturgical and musical manuscripts were unearthed and edited. Earlier, Dom Prosper Guéranger revived
15500-579: Was the Musica enchiriadis (c. 895), a treatise traditionally (and probably incorrectly) attributed to Hucbald of St. Amand . The oldest methods of teaching organum can be found in the Scolica and the Bamberg Dialogues , along with the Musica enchiriadis . The societies that have developed polyphony usually have several types of it found in their culture. In its original conception, organum
15625-401: Was to be taken. Some favored a strict academic rigour and wanted to postpone publications, while others concentrated on practical matters and wanted to supplant the corrupted tradition as soon as possible. Roughly a century later, there still exists a breach between a strict musicological approach and the practical needs of church choirs. Thus the performance tradition officially promulgated since
