"A rhizome as subterranean stem is absolutely different from roots and radicles. Bulbs and tubers are rhizomes. The rhizome includes the best and the worst: potato and couchgrass. A rhizome ceaselessly establishes connections between semiotic chains, organizations of power, and circumstances relative to the arts, sciences, and social struggles. A semiotic chain is like a tuber agglomerating very diverse acts, not only linguistic, but also perceptive, mimetic, gestural, and cognitive; there is no language in itself, nor are there any linguistic universals, only a throng of dialects, patois, slangs, and specialized languages." - Deleuze and Guattari, A Thousand Plateaus

A Critical Transition in The Structure Of the Medieval Music; The Introduction Of Organum

In the Medieval Ages, listening to music was said to be one of the major entertainments of people ranked from below to top.  Music was played to the accompaniment of fairy tales and myths so that people could enjoy the stories together with the music, and in this way, a segmental entertainment was developed rather than merely listening to the yarns spun by the storytellers known as Bards. Along with the folk music, ‘plainsongs’ started to be used at the churches, which were “an importation from the East, imposed upon the newly converted people of western and northern Europe” (Ulrich, 56). Therefore, there emerged a conflict of tastes, and “the history of music in Middle Ages in large part reflected that conflict” (Ulrich, 56).
Medieval music, usually considered as falling between the 5th Century and 15th Century, is divided into two different periods in terms of the used instruments, textual forms, notation, and genres.  The first period is considered as the interval that falls between the 5th Century and 12th Century, specifically the 1150s, since very little is known about the time between the 5th Century and the 11the Century. The second period of the medieval music is considered to be between the 1550s and the beginning of the 15th Century, which was followed by Renaissance tradition (Hindley, 65).
The first period of the Medieval Music featured “the introduction of what may be called vertical troping, that is, the practice of adding new material above or below” (Ulrich, 56) of the horizontal movement of the notes. The introduction was about a new melody that was added to, and played together with the only melody of the songs of the previous centuries. Polyphony, “the style of simultaneously combining a number of parts, each forming an individual melody and harmonizing with each other” (Polyphony), is specified for the medieval music by H. Ulrich as “a chant sung at one pitch level by one group, and sung simultaneously at a fifth below by another” (57). Polyphony brought a great change in the textural forms of the western music and led music to an evolvement that constituted the western music we know today (Hoppin, 187). Therefore, the aim of this paper is to show this crucial change and its reflections in the traditional western music, give information about the first examples of polyphonic music and its structure by concentrating on the insight of the medieval compositions, and also illustrate this change with examples.
Before the polyphonic melodies were used in the history of music, pieces were usually consisted of a single melody that repeated itself several times, usually to accompany a story that was orally told rather than solely to be listened to. A horizontally single-lined melody is called monophonic. Here is an example of a monophonic melody that is formed by a single melody:

                             (Cassidy, Monophonic Texture)

As it is seen, the melody goes with a single note at a particular time and no single note has a harmonic note until the end of its duration. That means, the audience hears only a sound after a sound of a plain and flat melody. Therefore, one can conclude that monophonic music was, not completely but to a great extent, a part of the storytelling process rather than a form of art by itself.
Towards the end of the first medieval music period, music was transformed into a form that was dominated several harmonic melodies and accepted as a way of entertainment by itself with the introduction of polyphony. “The earliest unmistakable reference to harmonized music appears to be in Hucbald’s De harmonica institutione (Hughes, 276). Hucbald was a monk of St. Amand in Flanders, whose reference to simultaneous sounds is accepted as the most convincing statement and one of the earliest descriptions of harmonized medieval music made back in the medieval period; Hucbald writes:
Consonance is the calculated and concordant combination of two notes, which will only occur if two notes of different pitch are combined to form a musical unity, as happens when a man and a boy sing the same tune, or in what is generally known as organizationem. (Hughes, 277).
It might be concluded that the word organization stands for a structure of part-singing. Here is an example of a part-singing melody:

                                                    (Fletcher, Parallel Melody Lines)

This new way of composing music is called Organum by a written agreement on music, entitled Musica Enchiriadis, which “was formerly attributed to Hucbald, but it is now, after proposals to ascribe it to other authors, reckoned as anonymous” (Hughes, 277), and dated to sometime around the second part of the 9th Century (Christensen, 480). It is widely accepted that Organum was the first step that enlarged the imagination of many composers, such as Johann Sebastian Bach and George Frederic Handel, who evolved music in the following centuries and shaped the music form that is known as the traditional western music today.
Although Organum, as a technique, can be described in significantly different ways, considering the period in which the work was composed, Musica Enchiriadis talks about a practice that determines a standard form for the early examples of polyphonic melodies. According to that standard, “the first group sings the vox principalis (principal voice) and the second group sings the vox organalis (organal voice)” (Ulrich, 57). Musica Enchiriadis suggests that polyphony is based the rule that the base notes should be included their fourths or fifths, sung by the second group. Here is an example of an Organum’s first notes:
                              Description: Alica Kyz:Users:alicakyz:Desktop:Perfect_fifth_on_C.png
                                       (C and G on the treble clef)

In the example, it is seen that the C note has its perfect fifth, G.  Organum’s first part follows this rule for its each note and every note is sung together with its fourth or fifth. To illustrate, if we have a sequence of C-D-E (base notes), the organum of that base notes should be included either G-A-B (the fifths), or F-G-A (the fourths). Hence, an Organum’s first part looks like:
Description: Alica Kyz:Users:alicakyz:Desktop:Organum.gif             
        (Te Deum, two-voiced)

The above example is from Te Deum which was one of the earliest examples of Organum and is named as “strict organum” in the Musica Enchiriadis (Ultan, 52). The ‘original voice’ in the Te deum may be said to be the equivalent of vox principalis and the ‘organum’ is the equivalent of vox organalis. Consequently, some harmonized, two-voiced compositions came into the ears with the practice of Organum in the Middle Ages, which, inevitably, led the western music to evolve into the shape of what it is today.
Octaves, “the interval between the two notes at the extremes of an octave” (Octave), in a composition are not compulsory, but each voice can be doubled, according to Musica Enchiriadis, with “the principalis an octave below and the organalis an octave above, resulting in a texture comprising four parallel lines” (Ulrich, 57).     
Description: Alica Kyz:Users:alicakyz:Desktop:organum doubled.gif
 (Te Deum, four-voiced)

Here in the example, one can see that the original voice has its octave below while the organum has its octave above, and a four-voiced composition is formed. This doubling method was useful when a choir of boys and men were entrusted with the part-singing performance (Ulrich, 57). However, either the simple type (two-voice) or the compound type (four-voice) was used, one can understand that the principal rules for parallel writing were practiced and chants that were treated in parallel organum were produced in the Middle Ages.  
In conclusion, it must be stated that the first period of medieval music was a time when a great change occurred in the history of musical compositions. The introduction of polyphonic melodies was a revolution for the traditional western music. Although there were many changes in the period from the point of instruments, notation and genres, the change in the textual form of the pieces was the greatest one. Organum, the name given to the earliest practices of polyphonic music, was produced with the apposition of the fourths or fifths of the base notes to the principal melody and sometimes, a four-voiced structure was created by the addition of octaves, as it is described in the Musica Enchiriadis which was an anonymous work commenting on the period’s music.
