Music and mathematics might be seen as two different sides of the same coin; and "yes", there is such a coin with prominent examples like
- the music melodies (which lie exactly between the red (Brownian motion) and the white (derivative of the Brownian motion) noise
- the music of the primes (and its relationship to the Berry-Keating conjecture and the RH).
Gödel's two incompleteness theorems already show the boundaries of mathematics (and therefore also the boundaries of all theoretical physics models) with respect to the two terms "truth" and "povability" within this (ideal) mathematical world.
As music art is only a subset of "fine arts", there exists another larger coin, including e.g. painting:
beside the usual suspects (during the last centuries until today), there are many undiscovered (sufficient in themselves) juwels contributing to the painting oriented "human creativity", where mathematics do also have a relationship (symmetry, perspective), as well, but truly only as a describing science to provide tools w/o "truth" and "provability" entitlement:
