"Néanmoins le profond savoir qu'on remarque dans l'ouvrage de Francon, et l'obscurité dans laquelle sont ensevelis et les noms et les œuvres de ceux, auxquels il attribue la première invention de la musique mesurée, le feront à jamais regarder comme le premier auteure de cette importante découverte." [Fétis, Mémoire sur cette Question: "Quels out été les mérites des Neerlandais dans la musique," etc.--Question mise au concours pour l'année 1828 par la quatrieme classe de l'Institut des Sciences, de Litterature et des Beaux Arts du Royaume des Pays-Bas.] With harmony and measure governed by rules and the written page at hand as a conserving power, systematic composition became a possibility. The study of this art was the work of monks, who were the repositories of polite learning in the middle ages, and they naturally sought for their thematic material in the plain chant of the church. Their treatment of this chant was a natural outgrowth of the impromptu production of music which had preceded systematic composition and which clung to existence with great pertinacity. Guido of Arezzo had taught choristers the art of singing with such success that they began the long-honored custom of adding ornaments to their melodies. They carried this practice to such an extent that it became necessary for one singer to intone the melody while another sang the ornamental part. This adding of ornamental parts was called the art of discant; and when the monks took up scientific composition they simply added discants to the liturgical chants of the church. This was the beginning of counterpoint, the art of writing two or more melodies which shall proceed simultaneously without breaking the rules of harmony. The name "counterpoint" was early applied to it by Johannes de Muris, doctor of theology at the University of Paris in the beginning of the fourteenth century. This indicates that by his time the scientific setting of note against note had fully superseded discant, the fanciful elaboration of the singers. It was in the hands of the great masters of the Netherland school that this counterpoint, the first species of scientific composition, was developed to its highest perfection. In the main the differences between their counterpoint and ours are due to the cramped harmony of their time, which was fettered by the employment of the Gregorian scales. The superiority of Bach's counterpoint over theirs from a technical point of view is the result of his mastery of chromatics and his perfection of the system of equal temperament. With the aesthetic superiority of his work we need not concern ourselves, for we must bear in mind the fact that most of the Netherland masters were absorbed in developing the technical construction of music, and had little to do with the exploration of its emotional possibility.
