And without music there can be no perfect knowledge, for there is nothing without it. For even the universe itself is said to have been put together with a certain harmony of sounds, and the very heavens revolve under the guidance of harmony.
Itaque sine Musica nulla disciplina potest esse perfecta, nihil enim sine illa. Nam et ipse mundus quadam harmonia sonorum fertur esse conpositus, et coelum ipsud sub harmoniae modulatione revolvi.
