One might ask why at each epoch not all the music was given; why only a single note. The answer is that there are times in the life of an infant when a rattle is sufficient; for the violin another time in life is more appropriate. During the time of the Chaldeans, Arabs, Greeks, and Romans, different religious ideals were brought to humanity. To the few music was brought, to the many only a note; and this shows that this music has always existed, but that man in general was not ready to grasp it and so was given only one note.
