Clever way to make the hidden pattern of primes audible.
From 1 comment
Very cool. Primes have such an irregular yet structured distribution, and mapping them to pitches is a clever way to make that hidden pattern audible.

Objections
Doubt the output differs meaningfully from random numbers fed through the same algorithm.
From 1 comment
I don't think there's any insight available here. I doubt anyone could distinguish this from an RNG fed into the same algorithm without memorizing.

Requests
Map primes directly to Hz instead of piano scales.
From 1 comment
I wonder how it sounds if you map the primes straight onto Hz instead of piano scales.

An earlier attempt mapping primes to minor scales, shown in a linked video.

Nice job. Related, I remember seeing an attempt at mapping primes to minor scales a few years back. https://www.youtube.com/watch?v=duVyBVNX3D8
