An anonymous reader writes: As an amateur composer and pianist, I frequently see music that I would like to change or rewrite as a personal interpretation of the writer's intent. Although I love to make modifications and change the way a piece is written, it is obviously impossible for me to claim any such a hybrid as my own work, nor as the original author's. Perhaps could a model similar to the open source software movement's be used to collaboratively create music among an array of composers, each adding their own personal thoughts? Admittedly, it would be difficult for many composers to agree on what sounds best, but I imagine similar difficulties are involved in creating open source software. I would love to see composers making music under the GPL, so that many others could do this, but I am not sure if such a model would work.
