In 1960 John Cage appears in a popular TV show and performs the music piece water walk. He uses sounds of everyday objects to compose. His carefulness and very precise actions show that he must have rehearsed hundred of times to perform his piece. Via multimedialab.
Recently, Nicholas Knouf created an interactive version of John Cage’s graphical score Variations 2, called Variations 10b. I tried it during an exhibition at the Lewis Music Library at MIT and found the interface very convincing. The interface allows a performer to change the score and get immediate feedback as to the result. Nicholas hopes that both listeners and performers will develop a more nuanced understanding of the score through the use of the interface.
