As a programming exercise (I was learning the language a year and a half ago and have not reviewed the code more recently; I make no promises about the code quality) I made a tool to convert Lilypond notation into Grub beep code: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=5d90dfae99efdfd1529c335140ecb110
It uses hardcoded notes but anyone who knows Rust could probably turn it into something that takes an input relatively easily.
The thing I hardcoded into the above link produces
which Iʼm surprised nobody listed before.
Other things Iʼve tried (Westminster chimes, Still Alive) didnʼt work that well, but this did.
Someone else came up with shave and a haircut
not using my tool.
