The first steps toward actually defining the new music took place in the second century, when the Christians were free to worship more openly, and, having wealthy converts among them, held their meetings in public places and basilicas which were used by magistrates and other officials during the day. These basilicas or public halls had a raised platform at one end, on which the magistrate sat when in office. There were steps up to it, and on these steps the clergy stood. The rest of the hall was called the “nave” (ship), for the simile of “storm-tossed mariners” was always dear to the early Christian church. In the centre of the nave stood the reader of the Scriptures, and on each side of him, ranged along the wall, were the singers. The Psalms were sung antiphonally, that is, first one side would sing and the other side would answer. The congregations were sometimes immense, for according to St. Jerome (340-420 A.D.) and St. Ambrose (340-397 A.D.) “the roofs reechoed with their cries of ‘Alleluia,’ which in sound were like the great waves of the surging sea.”
Nevertheless this was, as yet, only sound, and not music. Not until many centuries later did music become distinct from chanting, which is merely intoned speech. The disputes of the Arians and the Athanasians also affected the music of the church, for as early as 306 A.D., Arius introduced many secular melodies, and had them sung by women.
Passing over this, we find that the first actual arrangement of Christian music into a regular system was attempted by Pope Sylvester, in 314 A.D., when he instituted singing schools, and when the heresy of Arius was formally condemned.
Now this chanting or singing of hymns was more or less a declamation, thus following the Greek tradition of using one central note, somewhat in the nature of a keynote.
Rhythm, distinct melody, and even metre were avoided as retaining something of the unclean, brutal heathenism against which the Christians had revolted. It was the effort to keep the music of the church pure and undefiled that caused the Council of Laodicea (367 A.D.) to exclude from the church all singing not authorized from the pulpit.
