THERE is one peculiarity of the early attempts at writing in several melodious parts which must now be brought to the attention of the reader, and which is very difficult to explain to a person not versed in musical laws. Instead of writing free melodies to accompany the fixed chants, the early composers took up the practice of making the tune serve as its own accompaniment by the employment of a number of ingenious devices, all included in the art of counterpoint. I shall presently endeavor to explain the nature of this style of writing; but as it began in France, we must first note the historical facts in connection with the development of musical art in that country. The reader will remember that Charlemagne established schools for the cultivation of the Roman chant in many French towns. History shows us that the connection between France and the Roman Church grew closer and closer until, under Philip the Fair, the State dominated; and in the beginning of the fourteenth century the papal court was removed by the king to Avignon. In the twelfth century the University of Paris became the centre of study in Europe. It was natural in these circumstances that the cultivation of Roman Catholic church music should have flourished in Paris, and that, about 1100 A. D., a distinct school of French composers should have developed. This school flourished until 1370, and there has descended to us a knowledge of nearly five hundred composers who belonged to it. It would be impossible and useless to attempt to tell the reader all about these composers. What I desire to do is to point out what this school accomplished in the development of music.
Counterpoint is today the art of constructing two or more melodies which can be sung or played simultaneously without breaking the rules of harmony. Originally, however, it was the art of adding parts above or below a part already selected. It originated, as we have seen, in the practice of the descanters. A part improvised by a descanter came to be called contrapunctus a mente (a counterpoint out of the head), while an additional part written by a composer was called contrapunctus a penna (a counterpoint from the pen). As musicians acquired skill in the construction of these additional parts, they began to introduce new devices, and to write with greater and greater freedom. The more free their writing was, the further it tended to depart from parallel motion. In the course of time some one hit upon the musical device called "imitation," which means the repetition in a secondary part (say the bass) of some passage already heard in the principal part (the treble) while that principal part is still going on. The result of this device is that one portion of a melody is made to serve as the second voice to another portion of it. Who first hit upon this device, no one knows; but the earliest example of it which has been preserved is found in the "Posui adjutorum" of Perotin, one of the first of the French school of writers. Here is the passage; and by giving it careful study the reader will be able to understand the fundamental principle of canon, fugue, and all the polyphonic forms:—

I think that even a reader who is not a musician can understand this. A is the first half of a melody, and B is the second half. While the first voice is singing the first half, the second voice sings the second half as the alto part of the first half. In order to make the first half act as alto in the second half, the composer had to push the second voice one bar ahead of the first voice, and then to add three extra notes to A in order to make a conclusion to his alto part. There are two imitations in this bit: the second half of the part sung by the first voice imitates the first half of the second voice part, and the second half of the second voice part imitates the first half of the first voice part.
By extending and developing such imitation as this, composers came to write in "double counterpoint," which means the construction of two parts in such a way that their different portions can be transferred from one to the other just as they are in the selection from Perotin. The reader will see at once that composing in this manner required a great deal of calculation, and was a constant tax on the ingenuity of the musician. In its early stages it prevented any attempt at making music expressive, and reduced composition to a mere exercise of scientific skill. But it forced the composers to a close study of the materials of their art, and they acquired a great mastery over them and constantly learned more and more about the possibilities of music. Double counterpoint, which is at the foundation of the most rigid forms of polyphonic writing, was generally known in the French school at least as early as the thirteenth century, but the example from Perotin seems to show that at least some of the composers knew it much earlier. This might account for the existence of the celebrated example of early English polyphony, a "canon" called "Sumer is icumen in." This was discovered by Sir John Hawkins, who wrote a history of music in 1776. Its manuscript was copied by a monk of Reading, John of Forneste, in 1228, and it must have been composed shortly before that time. The fact that Walter Odington, an Englishman, wrote a treatise on music in 1230, when the only famous school was that of Paris, leads me to believe that these early English composers were disciples of the French. But it is certain that the composer of "Sumer is icumen in" was a greater master of counterpoint than his teachers, because this "canon" is the finest specimen of polyphonic writing that has come down to us from those early times. Here is its beginning:—

Chorus:
Su-mer is i-cu-men in . . .
Lhu-de sing Cuc-cu,
Grow-eth sed, and blow-eth med,
And springth the w-de nu . . .
Sing Cuc-cu . . .
I urge the reader to give careful attention to the remarkable interweaving of the first four voice parts. At the fifth bar of the melody, in the first voice, the second voice enters with the beginning of the air. When the second voice reaches the fifth bar of the air, the third voice comes in, and at the same time the first voice begins the second half of the melody. When the third voice reaches the fifth bar of the first half of the air, the fourth voice comes in, and the second voice begins the second half. And so it goes on, the entrances always being made according to the rule established at the start, and each voice singing the tune without the alteration of a single interval to make it fit into the scheme. Rigid imitation of this kind is called "canon." In this particular canon the two lowest voices have a bass in two parts, written in double counterpoint, which they sing over and over again all the way through. A constantly repeated bass is called a "basso ostinato," and this is the first example of it.
This kind of writing possessed the merit of high organization, without which there can be no work of art. One might search in vain for evidences of artistic design in the early Gregorian chant, while in such works as those of the early Frenchmen and their English disciples they confront one in every measure. The result was that these writers developed several kinds of contrapuntal writing. But it must be admitted that their work was cold and mathematical, being wholly the result of ingenious calculation. Furthermore it must be borne in mind that they had no conception whatever of music as a means of expression. In a vague way they felt its suitability to the worship of their churches, and its Gothic complexity did indeed harmonize well with ecclesiastical architecture. But it never occurred to the composers of the French school to try to make music beautiful for its own sake. They were too busy exploring the resources of their art, and their materia musica was as yet too scanty to allow them to treat their art with the command of mastership. But they served well the cause of music by discovering many of its essential rules, and by formulating in their treatises much of its fundamental theory. It is not at all surprising that in the last period of this school we meet with a large work. The last important master of the school was William of Machaut, who flourished between 1284 and 1369, and wrote the mass for the coronation of Charles V. of France.
The teachings of the French spread into Belgium, and there arose a school called the Gallo-Belgic. The first evidence of its existence is found in the mass of Tournay, sung by the choristers of the Tournay cathedral. Its composer is unknown, but it was written about 1330. It is in three parts, the tenor (voice carrying the fixed chant) in the middle, the descant (or counterpoint) above, and a bass below. It is not nearly so well developed in its polyphony as "Sumer is icumen in" or the works of the Frenchmen. Two of its voices move always in parallel fourths or fifths (as in Hucbald's "organum") and the other has a contrary motion. The most famous composer of the Gallo-Belgic school was William Dufay, born 1400, died 1474. He almost wholly abandoned the use of parallel fourths and fifths, which did so much to restrict composition, and he also adopted the open-note notation, which had made its appearance in France in the closing years of the French school. Dufay used the following notes:—

I have placed under Dufay's notes their present equivalents, with the names. Dufay is the first composer of whom it is known that he made earnest efforts toward a more plastic style of composition than that previously in vogue. This was undoubtedly due to the considerable development of the art of composition. In his search after a freer style, he abandoned the strict "canon," and used "imitation" only here and there in his works. Furthermore, he discerned the musical worth of the songs of the people, and in doing so paved the way for the exertion of a large influence by folk-song upon artistic composition. His method of using the popular songs, however, was as bad as it was remarkable. In composing a mass he would substitute in place of the fixed chant of the liturgy some popular air; and he put the words in along with it, probably because the words of the liturgy could not be sung to the tune. Hence, in three masses by Dufay, still extant, the melodies and texts of three songs of his day are found. One of these songs, "L'Omme Armée," became such a favorite that for more than a century nearly every prominent composer wrote a contrapuntal mass around it. This abuse had finally to be checked by the authorities of the Church. Dufay did another thing, of more benefit to music. He wrote some music in a very simple style, in which there were passages of pure chord harmony, such as we use in our music today. As an example of this, I quote the beginning of a fragment of one of his masses, reproduced in Naumann's "History of Music":—

Before Dufay's death the Gallo-Belgic school began to be overshadowed by that of the Netherlands, with which the art of writing unaccompanied church counterpoint reached its climax. To this school we must now turn our attention.
