My family is full of music theorists, including a professor of it. I’ve asked this before, and they’re of the thinking that no, one’s aptitude at music theory is not related to a knowledge of mathematics. The professor in my family has in particular seen no relationship between the two in their decades of teaching. But - importantly - a background of math can be a tremendous asset later in one’s career as a music theorist. It can help provide a unique way of looking at and improving on theory.
