It is hardly necessary to tell the reader that the methods employed in writing church music prior to the dawn of the seventeenth century were not always judicious. The use of secular tunes together with their texts prevailed for more than two centuries, and led to great laxity in the treatment of the liturgy. In the course of time too many composers came to regard the words of the mass as mere pegs to hang tunes on, and the tremendous complexity of the huge polyphonic works was such that the words could not be distinguished. One part would be singing "gloria in excelsis" while another was thundering "et in terra pax," and there was such a jumble of words and music that, while it was all very imposing, it was not comprehensible to the congregation. As long as the congregation knew very little Latin, and less music, this condition did not have serious effects; but the time had now come when the people began to ask questions. It becomes our duty, then, to inquire what influences led to reforms in church music. I shall first enumerate the influences and afterward discuss them in detail. 1. The revival of Greek learning in Italy after a lapse of seven hundred years. 2. The invention of printing. 3. The Renaissance. 4. Popular music. 5. The diffusion of musical learning among the people. 6. The Lutheran choral hymn and congregational singing. In 1453 the Turks, under Mohammed II., slew Constantine, last of the Roman emperors, and overthrew Rome's eastern empire, whose capital was Constantinople. The Christian scholars of Turkey fled toward the home capital of their fallen empire, and took up their residence in Italy. These scholars were all masters of the Greek tongue, and they awakened a new interest in it and its literature. The field had been untouched for about seven centuries, and the whole treasury of Greek history, oratory, and poetry was reopened to the Italian mind. Its effects were wide and general. One of them was to lead to the study of the New Testament in the original tongue, and this study very speedily demonstrated the unworthiness of the Latin Vulgate used by the Church. Any blow at Latin was a blow at the authority of Rome. The whole Italian system of worship had been built upon the Vulgate, which was in the language authorized in the Roman Church throughout western Europe, and used as the sole means of intercommunication between its branches in various nations. Doctrines and edicts alike proceeded from Rome in the ancient language of the city, and to throw discredit upon the veracity of that tongue in the Vulgate was to subject it to general doubt and suspicion. Such doubt did certainly spread among the people, who began to demand a clearer comprehension of the liturgy. To this end they desired a less complex setting of the musical part of the church service.
