Church Music in the Middle Ages (500-1450)
Gregorian chant represents the continuing musical tradition of the Catholic Church. In legend at least, the regularization of Christian chant has been consistently attributed to the 6th century Pope St. Gregory the Great.
Gregorian chant is, in fact, the form of plainchant that largely, but not entirely, replaced local forms of chant during the Middle Ages. Manuscript sources from the 10th and 11th centuries are preserved, but these are clearly part of an earlier tradition. In popular usage, the term Gregorian chant is generally acceptable to describe the official chant of the Church. This chant has musical value and interest in itself.
However, since much of the liturgical music of the Middle Ages and the Renaissance was based on melodies drawn from this body of music, its historical musical importance is immeasurable. In later centuries, the 19th century in particular, the connotations of elements of the chant continued as part of the common fund of music from which composers drew inspiration. For example, the opening notes of the chant for the Dies irae (Day of Wrath) from the Requiem Mass, provided the thematic allusion for Liszt's Totentanz and an ideé fixe for Rachmaninoff.

Gregorian chant is monophonic, modal, and in free rhythm. It has a single melodic line, without harmonic or polyphonic elements, and makes use of the eight church mode scales represented by the white notes of the modern keyboard starting on D (Dorian mode), E (Phrygian mode), F (Lydian mode) and G (Mixolydian mode), the names drawn from the different ancient Greek modes. The rhythm of the chant follows that of the words. It is possible to classify types of chant very simply as syllabic, neumatic, and melismatic. Syllabic chant, as typically represented in the musical settings of the Psalms, takes one note to a syllable. Often used in the hymns of Gregorian chant, neumatic chant may use groups of from two to four notes to a syllable, whereas melismatic chant indicates the use of a large group of notes for one syllable, as found in the florid music for the alleluias of the liturgy.

Musical Forms of Gregorian Chant
The Proper of the Mass
The chants of the Proper of the Mass are those that differ from day to day, according to the season or the saint or event to be celebrated.
The Introit
The Introit accompanies the entrance procession of the celebrant and his ministers.
The Gradual
The Gradual is one of the reading responses. It is constructed from a form of psalmody with refrain. Originally, the congregation responded with a simple formula to a soloist who sang the verses of the psalm one by one. However, due to the musical enrichment, the less literary texts were used during the 5th and the 6th century.
The Alleluia
The literal translation of this is Hebrew word is "Praise the Lord." Originally, this was a chant reserved for Easter day. However, it is now used in weekly celebrations of the Resurrection.
The Offertory
This is an accompaniment to the ceremonies.
The Communion
This chant accompanies the procession of distribution communion.

The Ordinary of the Mass

Kyrie
The Kyrie acclaims the Lord and implores his mercy. This chant is placed at the beginning of the Mass to prepare the congregation for the celebration.

Gloria
This hymn is believed to date from as early as the second century. Originally, the Gloria chant was used only at the midnight Mass on Christmas. However, today, it is used for the great feasts of the year and on Sundays.
Credo
The Credo is the main statement of faith of the congregation—the belief in one God embodied in the Nicene Creed first formulated in AD 325. The Credo was adopted as a legitimate part of the service by the Church of Rome in 1014. Perhaps because of its length (the longest in the mass), it is usually recited rather than sung. In musical settings, however, it is customary for the first line of the Credo to be intoned by the celebrant alone (I believe in one God), or by a soloist, and for the congregation to join in with the second line (Omnipotent Father).
Sanctus
The Sanctus is usually sung at the end of the prayer where the bread and wine are consecrated. It is the part of the mass where the worshippers join with the angels in praise of God with the words "Sanctus, Sanctus, Sanctus," as in the "Hymn of the Seraphim" reportedly heard in the Temple of Jerusalem by the prophet Isaiah. Its purpose is to invite the Church on earth to join in the liturgy of heaven.
Agnus Dei
The Agnus Dei, the invocation to the Lamb of God, is the chant that accompanies the rite of consecration and breaking of the bread, i.e., the holy Host. This breaking precedes its distribution at the communion of the faithful. The text in english says:
Lamb of God, you who take away the sins of the world, have mercy upon us.
Lamb of God, you who take away the sins of the world, have mercy upon us.
Lamb of God, you who take away the sins of the world, grant us peace.

Transition to a New Era (Beginning of the 15th Century)
In the early 1400s, two new schools of composition emerged as the spiritual predecessors of Renaissance music. The first school was established in England, which, before this point, had been somewhat musically isolated. The second school was in the Burgundy region of France.
England
English composers in the Middle Ages were geographically separated from the continental music of Machaut and the Notre Dame School. As a result, they developed a style that incorporated folk music influences. They had a stronger interest than their continental peers in the harmonic implications of putting two melodies together, and they used intervals of 3rds and 6ths more freely in their music. These intervals are the same as those used to create the chords we hear in music today. (Medieval music often sounds foreign to our ears because the chords contain intervals that are no longer used.) The Middle Ages in England gave us the carol, a monophonic dance form that, over time, evolved into a polyphonic religious poem. The carol often combines English text with Latin verse, as in the carol, There is no Rose. It is this later incarnation of the carol that we still associate with Christmas music today.
The principal composer of English music at this time was John Dunstable (c.1390-1453). His harmonic style provided a bridge between the abstract musical approach of the Middle Ages and the more sensuous style that followed, which sought to find clarity through harmony. His surviving compositions number about 60 and include motets, Mass settings, and secular songs.

Burgundy
Besides being known for great wine, the Burgundy region of France was the home of Guillaume Dufay (c.1398-1474) and Gilles Binchois (c.1400-1460), the two most important transitional composers on the continent. The Dukes of Burgundy, who in fact supported Dufay and Binchois, were avid patrons of the arts, and provided protection for numerous artists among which was the Flemish painter Jan van Eyck (c.1390-1441).
Dufay is recognized as one of the greatest sacred music composers of the early 15th century. Works such as his Missa l'homme armé, from which comes this Kyrie, are masterpieces of late medieval sacred music. Both Dufay and Binchois also excelled in the composition of chansons, French secular songs that remained popular well into the Renaissance. Dufay's numerous chansons include Par droit je puis bien complaindre ("I have the right to complain").

A note on music treatises
The invention of polyphony is generally regarded as the most significant event in the history of Western music. With it, harmonic organization became a major concern for musicians and theorists. Harmony studies the organization and musical "laws" that govern sounds produced at the same time.
Consonance and Dissonance
Harmony is mainly concerned with the musical concepts of consonance and dissonance with which even the early theorists were preoccupied.
Treatises
Music treatises are the works produced by the theorists that try to explain and codify the music practices brought about by composers and performers of their time. Old music treatises are important to us because often they reveal insightful details about the nature and function of music, how music was composed, and, therefore, how it was performed during a certain period. This allows musicologists to try to reconstruct how music must have sounded to contemporary ears.
Early Theorists
Chief among early theorists are:
- Anicius Boethius (c.480-524), who seems to have been familiar with the concepts of consonance and dissonance.
- Flavius Magnus Aurelius Cassiodorus, (c.490-c.585), who wrote Instituiones musicae (Music Instruction).
- Hucbald (c.840-930) who wrote De harmonica institutione (Concerning Harmonic Instruction), in which he explains the theoretical basis for organum, which, in turn, originated polyphony.
