As a composer I agree to some extent. Like, I don't sit down and say "oh lets use some augmented sixths today", but I definitely refer back to the "rules" of music theory a lot when I get stuck or I'm looking for a way to communicate a certain mood in a piece.
And this kinda device-reference approach, I believe, is mathematical. And I also think that a lot of what makes music tick is that inherent usage of the musical language we study or grow up with. Truly original music imo doesn't really exist[0]; the intentional or unintentional borrowing of ideas is why music theory is a field of study: to describe the ways in which music works. I think even modern techniques (set theory, 12-tone rows, and atonal music overall) has to look at the existing rules and say "what can we do differently" -- even as Romantic-era composers got more adventerous in their use of texture, harmony, tonality, etc.
(The story of Charles Ives, who spent most of his younger life being "untrained" by his father to sing duets in overlapping keys and the like, is a good example of this.)
> ... actual composition, which is developed to a level that far exceeds the guidelines of species counterpoint itself
While true, I still think it's more of a spectrum than a binary "all or nothing" mathematical approach, which is why I believe that musicianship is more mathematical than not. I agree that it far exceeds the "use a forth and you're beheaded" approach but I'd be interested to hear music that is entirely free of some sort of process.
