Protarchus
Pro. I think I understand you in part, Socrates, but I need a clearer statement of some things.
Socrates
Soc. Surely my meaning, Protarchus, is made clear in the letters of the alphabet, which you were taught as a child; so learn it from them.
Socrates
Soc. Sound, which passes out through the mouth of each and all of us, is one, and yet again it is infinite in number.

Protarchus
Pro. Yes, to be sure.
Socrates
Soc. And one of us is no wiser than the other merely for knowing that it is infinite or that it is one; but that which makes each of us a grammarian is the knowledge of the number and nature of sounds.
Protarchus
Pro. Very true.
Socrates
Soc. And it is this same knowledge which makes the musician.
Protarchus
Pro. How is that?

Socrates
Soc. Sound is one in the art of music also, so far as that art is concerned.
Protarchus
Pro. Of course.
Socrates
Soc. And we may say that there are two sounds, low and high, and a third, which is the intermediate, may we not?
Socrates
Soc. But knowledge of these facts would not suffice to make you a musician, although ignorance of them would make you, if I may say so, quite worthless in respect to music.

Protarchus
Pro. Certainly.
