Development of music

After considering the development of music we have followed during this semester, what do you think about John Cage’s piece, “4’33””? Do you think his idea is valid, and do you think he expressed that idea in a valid way? Why or why not? What is your musical aesthetic or philosophy? Please list at least 3 pieces of music you listened to during the course that demonstrate what represents good music to you, and explain why you chose those pieces.
