The 4'33" is a work by John Cage, comprising of 4 minutes and 33 seconds of absolute silence. (A tribute to absolute zero: 273 seconds of silence). Is there a copyright issue here?
Copyright issue
I examine the copyright controversy surrounding John Cage’s 4'33", a work consisting of 273 seconds of absolute silence meant as a tribute to absolute zero. I'm looking into whether silence itself can be legally protected.
