With just one musician, you can really do an unlimited number of things on the inside of the piano, if you have at your disposal an exploded keyboard.
John CageWhether I make them or not, there are always sounds to be heard and all of them are excellent.
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.
John CageIf this word "music" is sacred and reserved for eighteenth and nineteenth century instruments, we can substitute a more meaningful term: organization of sound.
