If I asked you to “listen” silently to this page for 4’33″, would that be a copyright violation?
What if I attached a 4’33″ long mp3 of silence?
If I recorded it myself, would that be a forgery or a performance?
What if I used a kazoo instead of a piano?
Would 4’34″ of silence be a derivative work?
Would 15″ of silence, accompanied with this commentary, be an acceptable use excerpt?
Would the sound of one hand clapping be the appropriate sign of appreciation?
