One could say music is also a game with a strict ruleset. Indeed having played the piano for 20+ years now, I often think of how no matter how good I am, I won't invent a new form of music or even style of music, I am limited to the 'rules' of my piano.
One could not say that. The question is not about creating new styles or "forms" (??) of music. It is about creating compositions. I was only objecting to your use of AlphaGo as being based on "emotions" and being "creative". It is not generating explanatory knowledge, which is the kind of creativity we actually care about when we talk about AI. With current methods, you can only solve problems that have narrow optimization goals which are easily defined.
You might be. That hardly means that music is. Music is whatever humans think is cool to listen to.
Actually I think "inventing new forms of music" is a pretty great musical Turing test. How much neural-network training would it take to make an AI that can take the sum total of existing music, extrapolate the rules, and then deliberately break those rules in such a way as to make something that humans would find interesting?
That doesn't surprise me, if all you do is follow the rules of music theory on a standard piano. If you creatively deviate from music theory and modify your instrument (or create a new instrument) you could easily come up with something new, the question is whether anyone besides you would enjoy it.
