What is the meaning of Nete?

In Ancient Greek musical theory, the highest-pitched fixed note in the farther tetrachord on a lyre, always pitched a perfect fourth above the paramese, with two movable notes between them, the trite (lower in pitch) and the paranete (higher in pitch). The paramese was higher-pitched than the mese (the highest-pitched fixed note in the nearer tetrachord on a lyre) by a ratio of 9:8.
