I create music in code, and I create a live-coding tool that I call "WebAssembly Music". It's all code and math that generates music and instruments. An entire piece of music can be packed into a tiny file less than 50kb, and stored on the NEAR blockchain. Watch the talks about "WebAssembly Music" from WebAssembly Summit 2020, or NEARCON 2021 (on youtube). It is all open source, see https://github.com/petersalomonsen
