Doctrine of Ethos

Explanation:

The ancient Greeks believed that the right kind of music had healing powers and could positively shape one's character. This is what the doctrine of Ethos is. According to Aristotle, listening to the wrong kind of music could turn someone into the wrong kind of person. Certain instruments and modes would take one toward either the logos (rational behavior) or pathos (emotional behavior). It was important to find the proper balance between the logos and pathos, and listen to music that would turn someone into a good, balanced person.
