Silence can also be an important part of music, and the point was worth making.

Also the background noise in a live performance is also part of the live music experience. John Cage's instructions are "no sound is intentionally made" (my italics) so in a live performance of 4:33 any squeaking chairs, coughing, sniffing and breathing noises made by a live audience are deemed part of the musical experience.
