Concerning music (21-25)

The same may be said of Tyrtaeus the Mantinean, Andreas the Corinthian, Thrasyllus the Phliasian, and several others, who, as we well know, abstained by choice from the chromatic, from transition, from the increased number of strings, and many other common forms of rhythms, tunes, diction, composition, and expression. Telephanes of Megara was so great an enemy to the pipe made of reed (called syrinx), that he would not suffer the instrument maker to join it to the flute (pipe made of wood or horn), and chiefly for that reason forbore to go to the Pythian games. In short, if a man should be thought to be ignorant of that which he makes no use of, there would be found a great number of ignorant persons in this age. For we see that the admirers of the Dorian composition make no use of the Antiginedian; the followers of the Antiginedian reject the Dorian; and other musicians refuse to imitate Timotheus, being almost all bewitched with the trifles and the idle poems of Polyidus. On the other side, if we dive into the business of variety and compare antiquity with the present times, we shall find there was great variety then, and that frequently made use of. For then the variation of rhythm was more highly esteemed, and the change of their manner of play more frequent. We are now lovers of fables, they were then lovers of rhythm. Plain it is therefore, that the ancients did not refrain from

Having already shown that Plato neither for want of skill nor for ignorance blamed all the other moods and casts of composition, we now proceed to show that he really was skilled in harmony. For in his discourse concerning the procreation of the soul, inserted into Timaeus, he has made known his great knowledge in all the sciences, and of music among the rest, in this manner:

After this,

he filled up the double and treble intervals, taking parts from thence, and adding them to the midst between them, so that there were in every interval two middle terms.

Now that there is something of majesty, something great and divine in music, Aristotle, who was Plato’s scholar, thus labors to convince the world:

Harmony,

descended from heaven, and is of a divine, noble, and angelic nature; but being fourfold as to its efficacy, it has two means,—the one arithmetical, the other enharmonical. As for its members, its dimensions, and its excesses of intervals, they are best discovered by number and equality of measure, the whole art being contained in two tetrachords.

But, according to natural philosophy, both harmony and its parts consist of even, odd, and also even-odd. Altogether it is even, as consisting of four terms; but its parts and proportions are even, odd, and even-odd. So nete is even, as consisting of twelve units; paramese is odd, of nine; mese even, of eight; and hypate even-odd,

But now as for the senses that are created within the body, such as are of celestial and heavenly extraction, and which by divine assistance affect the understanding of men by means of harmony,—namely, sight and hearing,— do by the very light and voice express harmony. And others which are their attendants, so far as they are senses, likewise exist by harmony; for they perform none of their effects without harmony; and although they are inferior to the other two, they are not independent of them. Nay, those two also, since they enter into human bodies at the very same time with God himself, claim by reason a vigorous and incomparable nature.
