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 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 (500–1150), High (1000–1300), and Late (1300–1400) medieval music.
Music theory is the study of the practices and possibilities of music. The Oxford Companion to Music describes three interrelated uses of the term "music theory": The first is the "rudiments", that are needed to understand music notation ; the second is learning scholars' views on music from antiquity to the present; the third is a sub-topic of musicology that "seeks to define processes and general principles in music". The musicological approach to theory differs from music analysis "in that it takes as its starting-point not the individual work or performance but the fundamental materials from which it is built."
Guido of Arezzo was an Italian music theorist and pedagogue of High medieval music. A Benedictine monk, he is regarded as the inventor—or by some, developer—of the modern staff notation that had a massive influence on the development of Western musical notation and practice. Perhaps the most significant European writer on music between Boethius and Johannes Tinctoris, after the former's De institutione musica, Guido's Micrologus was most widely distributed medieval treatise on music.
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.
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 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.
Franco of Cologne was a German music theorist and possibly a composer. He was one of the most influential theorists of the Late Middle Ages, 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, described most famously in his Ars cantus mensurabilis.
Johannes Cotto was a music theorist, possibly of English origin, most likely working in southern Germany or Switzerland. He wrote one of the most influential treatises on music of the Middle Ages, De musica, first printed by Gerbert in 1784. The treatise included unusually precise directions for composing chant and organum.
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.
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.
Aurelian of Réôme was a Frankish writer and music theorist. He is the author of the Musica disciplina, the earliest extant treatise on music from medieval Europe.
Hucbald was a Benedictine monk active as a music theorist, poet, composer, teacher, and hagiographer. He was long associated with Saint-Amand Abbey, so is often known as Hucbald of St Amand. Deeply influenced by Boethius' De Institutione Musica, Hucbald's (De) Musica, formerly known as De harmonica institutione, aims to reconcile ancient Greek music theory and the contemporary practice of Gregorian chant with the use of many notated examples. Among the leading music theorists of the Carolingian era, he was likely a near contemporary of Aurelian of Réôme, the unknown author of the Musica enchiriadis, and the anonymous authors of other music theory texts Commemoratio brevis, Alia musica, and De modis.
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.
A tonary is a liturgical book in the Western Christian Church which lists by incipit various items of Gregorian chant according to the Gregorian mode (tonus) of their melodies within the eight-mode system. Tonaries often include Office antiphons, the mode of which determines the recitation formula for the accompanying text, but a tonary may also or instead list responsories or Mass chants not associated with formulaic recitation. Although some tonaries are stand-alone works, they were frequently used as an appendix to other liturgical books such as antiphonaries, graduals, tropers, and prosers, and are often included in collections of musical treatises.
Scolica enchiriadis is an anonymous ninth-century music theory treatise and commentary on its companion work, the Musica enchiriadis. These treatises were once attributed to Hucbald, but this is no longer accepted.
Daseian notation is the type of musical notation used in the ninth century anonymous musical treatises Musica enchiriadis and Scolica enchiriadis. The music of the Musica enchiriadis and Scolica enchiriadis, written in Daseian notation, are the earliest known examples of written polyphonic music in history.

De Mensurabili Musica is a musical treatise from the early 13th century and is the first of two treatises traditionally attributed to French music theorist Johannes de Garlandia; the other is de plana musica. De Mensurabili Musica was the first to explain a modal rhythmic system that was already in use at the time: the rhythmic modes. The six rhythmic modes set out by the treatise are all in triple time and are made from combinations of the note values longa (long) and brevis (short) and are given the names trochee, iamb, dactyl, anapest, spondaic and tribrach, although trochee, dactyl and spondaic were much more common. It is evident how influential Garlandia's treatise has been by the number of theorists that have used its ideas. Much of the surviving music of the Notre Dame School from the 13th century is based on the rhythmic modes set out in De Mensurabili Musica.
Oktōēchos is the name of the eight mode system used for the composition of religious chant in most Christian churches during the Middle Ages. In a modified form the octoechos is still regarded as the foundation of the tradition of monodic Orthodox chant today.
