@TheRealPomax @Viss @molly0xfff But 4′33″ isn’t just silence! For one thing, it’s divided into three movements, which performers must communicate somehow. At a deeper level, 4′33″ is about the *impossibility* of silence.
(Also, the usual score specified that 4′33″ may “last any length of time.” Any attempt to raise a copyright issue would run into the compulsory license for music recordings, for one thing.)
@LiberalArtist @Viss @molly0xfff Copyright doesn't care about the underlying intent, only whether the work will reasonably be assumed to "be" another work. It's why derivative works can still be copyright violation.
And yes, that's idiotic. It'd be lovely if we could abolish all the nonsense around modern copyright law.
