You can help by adding to it. December The music theory of the Medieval period saw several advances over previous practice both in regard to tonal material, texture, and rhythm.
Concerning rhythmthis period had several dramatic changes in both its conception and notation.
During the early Medieval period there was no method to notate rhythm, and thus the rhythmical practice of this early music is subject to heated debate among scholars. This rhythmic plan was codified by the music theorist Johannes de Garlandiaauthor of the De Mensurabili Musica c. Each mode establishes a rhythmic pattern in beats or tempora within a common unit of three tempora a perfectio that is repeated again and again.
Furthermore, notation without text is based on chains of ligatures the characteristic notations by which groups of notes are bound to one another. The rhythmic mode can generally be determined by the patterns of ligatures used. In his treatise Ars cantus mensurabilis "The Art of Mensurable Music"written aroundhe describes a system of notation in which differently shaped notes have entirely different rhythmic values.
This is a striking change from the earlier system of de Garlandia. Whereas before the length of the individual note could only be gathered from the mode itself, this new inverted relationship made the mode dependent upon—and determined by—the individual notes or figurae that have incontrovertible durational values,  an innovation which had a massive impact on the subsequent history of European music.
Most of the surviving notated music of the 13th century uses the rhythmic modes as defined by Garlandia. The step in the evolution of rhythm came after the turn of the 13th century with the development of the Ars Nova style.
The theorist who is most well recognized in regard to this new style is Philippe de Vitryfamous for writing the Ars Nova "New Art" treatise around This treatise on music gave its name to the style of this entire era.
The notational predecessors of modern time meters also originate in the Ars Nova. This new style was clearly built upon the work of Franco of Cologne. In Franco's system, the relationship between a breve and a semibreves that is, half breves was equivalent to that between a breve and a long: Sometimes the context of the mode would require a group of only two semibreves, however, these two semibreves would always be one of normal length and one of double length, thereby taking the same space of time, and thus preserving the perfect subdivision of the tempus.
In contrast, the Ars Nova period introduced two important changes: These groupings of mensurations are the precursors of simple and compound meter.
For Vitry the breve could be divided, for an entire composition, or section of one, into groups of two or three smaller semibreves. This way, the tempus the term that came to denote the division of the breve could be either "perfect" tempus perfectumwith ternary subdivision, or "imperfect" tempus imperfectumwith binary subdivision.
While many of these innovations are ascribed to Vitry, and somewhat present in the Ars Nova treatise, it was a contemporary—and personal acquaintance—of de Vitry, named Johannes de Muris Jehan des Mars who offered the most comprehensive and systematic treatment of the new mensural innovations of the Ars Nova  for a brief explanation of the mensural notation in general, see the article Renaissance music.
Many scholars, citing a lack of positive attributory evidence, now consider "Vitry's" treatise to be anonymous, but this does not diminish its importance for the history of rhythmic notation. However, this makes the first definitely identifiable scholar to accept and explain the mensural system to be de Muris, who can be said to have done for it what Garlandia did for the rhythmic modes.
For the duration of the medieval period, most music would be composed primarily in perfect tempus, with special effects created by sections of imperfect tempus; there is a great current controversy among musicologists as to whether such sections were performed with a breve of equal length or whether it changed, and if so, at what proportion.
This Ars Nova style remained the primary rhythmical system until the highly syncopated works of the Ars subtilior at the end of the 14th century, characterized by extremes of notational and rhythmic complexity.
The rhythmic complexity that was realized in this music is comparable to that in the 20th century. Of equal importance to the overall history of western music theory were the textural changes that came with the advent of polyphony. This practice shaped western music into the harmonically dominated music that we know today.
These texts are dated to sometime within the last half of the ninth century. The first group comprises fourths, fifths, and octaves; while the second group has octave-plus-fourths, octave-plus-fifths, and double octaves. The early organum as described in the enchiriadis can be termed "strict organum"  Strict organum can, in turn, be subdivided into two types: If either of them paralleled an original chant for too long depending on the mode a tritone would result.
This second style of organum was called "free organum". Its distinguishing factor is that the parts did not have to move only in parallel motion, but could also move in oblique, or contrary motion.
This made it much easier to avoid the dreaded tritone. This new style was not note against note, but was rather one sustained line accompanied by a florid melismatic line. He united this style with measured discant passages, which used the rhythmic modes to create the pinnacle of organum composition.
Furthermore, this kind of polyphony influenced all subsequent styles, with the later polyphonic genera of motets starting as a trope of existing Notre Dame organums. Another important element of Medieval music theory was the system by which pitches were arranged and understood.
During the Middle Ages, this systematic arrangement of a series of whole steps and half steps, what we now call a scalewas known as a mode. In his work he describes three defining elements to each mode:The Middle Ages are so called as the middle period between the decline of the Roman Empire and prior to the period called the Renaissance.
