Yet I think if you define science as the knowledge gained through practice and study then knowing your scales and other theory could be called science.
But scales and other theory again is a derivative of the actual science of sound. They put slightly more human labels on audible frequencies and wave characteristics.
So if you try and analyse why music is what it is it's the science you're looking at. If you critique the music in musical terms it would probably be art. And both come down to the same thing in the end. One man's art is another man's science.
