So wrote Plato in The Republic (4. 424c) And Plato is famous for having given what is probably the 1st theory of character in music, proposing to allow some modes and to forbid others according to the character which can be heard in them. Plato deployed the concept of mimesis, or imitation, to explain why bad character in music encourages bad character in its devotees.
