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.
