I pleasantly learned today about John Cage and his take on music and sound. He famously composed 4’33” because “There is no such thing as silence. Something is always happening that makes a sound.”
As from wikipedia:
Cage is perhaps best known for his 1952 composition 4′33″, the three movements of which are performed without a single note being played. A performance of 4′33″ can be perceived as including the sounds of the environment that the listeners hear while it is performed, rather than merely as four minutes and thirty three seconds of silence and has become one of the most controversial compositions of the century.
This piece has been performed by a number of orchastras and peeps. The piece has 3 movements, and typically the musician does something to indicate that one movement is complete.
Here’s last year’s performance … (there is always one idiot who coughs):
