Disclaimer:
I will report from my point of view, which might be boring to some.

I have been experimenting with algorithmic music from the mathematical point of view since Covid, not so much from music point of view, and I would like to point to a positive definite kernel for measuring the consonance of two pitches:
$$k(a,b) = \frac{\gcd(a,b)^2}{ab}$$
The description can be find [here][1].
From the "sonification of math" point of view, I would like to mention the #InfinitePiChallenge where there [are given infinitely many formulas for calculating $\pi$][2] and the challenge is to pick one formula and sonify it. I did that with a few formulas, two of which I like to highlight:

[Convergence I, #InfinitePiChallenge for Violin and Cello][3]


[Convergence II, #InfinitePiChallenge for Piano][4]


[Here][5] you can find a graph theoretic approach to music generation with prime numbers.


[And here][6] you can find an experiment with roots of unity sonified with supercollider.

Do not forget the [subtle sonification of some prime numbers][7], which I have forgotten how I sonified it.
