If you develop an ear for sounds that are musical it is like developing an ego. You begin to refuse sounds that are not musical and that way cut yourself off from a good deal of experience.
John CagePercussion music is revolution. Sound and rhythm have too long been submissive to the restrictions of nineteenth century music. Today we are fighting for their emancipation. Tomorrow, with electronic music in our ears, we will hear freedom. At the present stage of revolution, a healthy lawlessness is warranted. Experiment must necessarily be carried on by hitting anything-tin pans, rice bowls, iron pipes-anything we can lay our hands on. Not only hitting, but rubbing, scraping, making sound in every possible way...What we can't do ourselves will be done by machines which we will invent.
