Hypothetical- If there were two editors who independently made performing editions of a piece of public domain music, and I performed that piece publicly from memory, how would they procede with a lawsuit against me? Assume that both were attempting to make the scores accurate to the composer's intent, so all the notes are the same. I think that this scenario highlights the fact that an editor hasn't created a new musical work. They've researched and collected information that was already public. If I write a history of WWI, collecting and editing all the information, does anyone who teaches a class, or gives a lecture agreeing with my interpretation, owe me royalties? It's the same scenario. The difference between these situations and a composer, is that the composer actually creates a new piece of music. One couldn't create a Chopin Nocturne by one's self. One could make an indentical urtext score of said Nocturne without using any urtext score. The ironic thing, is that in making a performing edition, the editor explicitly does not want to create new art. He wants to recreate what the composer wrote. If I were to make a performing score with all the same notes, how would anyone be able to prove that I took the knowledge from the other editor's score and didn't compile on my own. After all, if I research properly, I should end up with the same work.If we can give people copyrights for making 'new' art in a performing edition, why can't an interpretation be considered 'new'? Why not charge any performer who plays the Goldbergs to similarly to Gould?On a separate item, intellectual property law should be a practical thing. It's not some philisophical issue. It exists, not because someone deserves to have complete control over any knowledge they create, but because people need to be rewarded for making knowledge if we want any new knowledge created. This Hyperion decision goes completely against that practicality. This sort of IP law discourages art. If little Susie wants to perform an arrangement of a Disney song at her free recital, the law shouldn't get in her way. Anyone who disagrees with this is a jackass. I'll quote the kids of South Park. "Art belongs to the public." IP law merely exists to make sure that the maker of that art gets a just reward for his work.
