Nothing i guess. Ask anyone who knows music theory, there is a ton of math in music.

Source: I randomly socialize with a professional classical musician that does both playing and composing/analysis.

Well. What I mean is that people have used mathematics in order to create music for a long time. But you're correct that everything is mathematical in a sense.

People tend to like the same pieces of music, so there is obviously specific patterns that people generally like. AI is good at finding patterns so in the end AI will become good at creating music.

I think.
