Character is formed by many factors, music is only one of them. Music can cultivate taste and change people's mood. Listening to healthy music has a good influence on people's personality. But music cannot determine a person's personality. Therefore, music can only influence, but not determine, the formation of personality. The feeling that a song or a melody gives people is the true inner feeling of the composer, and when we coincide with his/her feelings, we will feel that this song and this melody are the most beautiful.
