Note 63 — Chapter V · THE AGE OF PLAIN-SONG

Here should be noted one of the ways in which the Christian theorists misapplied the system of the Greeks. In Chapter IV we have seen that the Greeks did not consider pitch as in any way related to the character or ethos of the modes. This ethos was determined solely by the arrangement of the steps in the scale. The Christian theorists, on the other hand, though they still recognized the variety of character obtained by varying the distribution of steps in the scale, evidently allotted to the different modes a different final or pitch, and thus pitch came to influence the character of the modes. The modes might, however, still be transposed and sung at any pitch.
