That is obvious.
Everyone can see already what we ought to say about them, if we are to be consistent with ourselves.
I fear, said Glaucon, laughing, that the word “everyone” hardly includes me, for I cannot at the moment say what they should be; though I may guess.
At any rate you can tell that a song or ode has three parts—the words, the melody, and the rhythm; that degree of knowledge I may presuppose?
Yes, he said; so much as that you may.
And as for the words, there will surely be no difference between words which are and which are not set to music; both will conform to the same laws, and these have been already determined by us?
Yes.
And the melody and rhythm will depend upon the words?
Certainly.
We were saying, when we spoke of the subject-matter, that we had no need of lamentation and strains of sorrow?
True.
And which are the harmonies expressive of sorrow? You are musical, and can tell me.
The harmonies which you mean are the mixed or tenor Lydian, and the full-toned or bass Lydian, and suchlike.
These then, I said, must be banished; even to women who have a character to maintain they are of no use, and much less to men.
Certainly.
In the next place, drunkenness and softness and indolence are utterly unbecoming the character of our guardians.
Utterly unbecoming.
And which are the soft or drinking harmonies?
The Ionian, he replied, and the Lydian; they are termed “relaxed.”
Well, and are these of any military use?
Quite the reverse, he replied; and if so the Dorian and the Phrygian are the only ones which you have left.
I answered: Of the harmonies I know nothing, but I want to have one warlike, to sound the note or accent which a brave man utters in the hour of danger and stern resolve, or when his cause is failing, and he is going to wounds or death or is overtaken by some other evil, and at every such crisis meets the blows of fortune with firm step and a determination to endure; and another to be used by him in times of peace and freedom of action, when there is no pressure of necessity, and he is seeking to persuade God by prayer, or man by instruction and admonition, or on the other hand, when he is expressing his willingness to yield to persuasion or entreaty or admonition, and which represents him when by prudent conduct he has attained his end, not carried away by his success, but acting moderately and wisely under the circumstances, and acquiescing in the event. These two harmonies I ask you to leave; the strain of necessity and the strain of freedom, the strain of the unfortunate and the strain of the fortunate, the strain of courage, and the strain of temperance; these, I say, leave.
And these, he replied, are the Dorian and Phrygian harmonies of which I was just now speaking.
Then, I said, if these and these only are to be used in our songs and melodies, we shall not want multiplicity of notes or a panharmonic scale?
I suppose not.
