This is a faulty argument: copyright law entitles you to own the
artistic expressions you create, and not the work that went into it.
If I would spend a long time to create a piece that happens to be the
same as something that Bach wrote, I can not enforce copyright on "my"
work.
I am not sure about what copyright says about urtexts and other such
recent editions of music that is itself in the public domain.
Does anyone know a forum where we can get more information about this?
I think the place to get better information is from a lawyer rather
than from a forum.
