Hmmm I’m not sure what you mean… Music can be treated very mathematically, that makes it no less artistic. Some people think that music created purely using mathematics and the rules of music produces something too rigid, but in my experience this doesn’t have to be so. Music like anything else is full or rules and guides, you can be a little more fluid with how rigorously you follow these unlike science. (free jazz is the exception to this, they don’t follow any rules….. but who likes free jazz)
As I don’t fully understand your question I am struggling to give you a better answer than this sorry.
I think art and science have slightly different goals. These goals can sometimes overlap, but don’t always. I think art is more focussed on expression and communicating, while science is more interesting in investigating and understanding. That’s not strict, and sometimes they overlap, as I’ve said. The science of music would have to do with recording technology, acoustics, and analysing musical structure, whereas the art of music is making music!
