Prepared Piano and John Cage

It’s the birthday of the avant-garde composer John Cage, born in Los Angeles, California (1912). He wrote pieces of music to be played on a variety of objects, including flowerpots, scrapped hoods of old cars and other pieces of junk. Then he began tinkering with a piano, shoving objects under the strings, including screws, bolts, spoons, clothespins, and even a doll’s arm. He said, “Just as you go along the beach and pick up pretty shells that please you, I go into the piano and find sounds I like.”

He kept adding new sounds into his compositions. His piece “Water Music” (1952) required a piano, a radio, whistles, water containers, and a deck of cards. He finally decided he wanted to explore silence, so as an experiment he entered a completely soundproof chamber at Harvard University. Instead of hearing nothing, he heard the sound of his own circulation and his nervous system. Afterward, he said, “No silence exists that is not pregnant with sound.” The experience inspired him to write his most famous piece,”4’33” (1952), in which the performer was instructed to sit silently at a piano for 4 minutes, 33 seconds, to draw attention to all the sounds being made by the audience members and the world around them.
