Thank you for your reply.
I understand your counter, and would accept the refutation except that the actual court cases do not hinge on minor variation. Of course it is true that there are an infinite number of combinations of the 12 tones, but they do not all sound good. Once you create a tonality, your melody will hover around five notes. After composition class we played a game converting various melodies to the pentatonic scale. It was fun and it was not the challenge that it sounds like. But the point is that your song is going to be played for a jury and it is going to sound like a host of other songs to them.
To apply my point to literature, there are a limited number of conflict ideas for your plot and Shakespeare covered them all in his career. If you can show that the idea you are using is in the public domain then you can get out of the infringement suit, but you cannot own your idea. There are an infinite number of dramatic ideas, but they are not all good. There are a limited number of ways to vary the plot ideas of Shakespeare, and soon if not already, all those ideas will be owned by somebody, and no one else can use them.
