You may want to use a different name from cs. cs is C sharp in english, so
this code would run into the same problem as you had before with c if
somebody wants to use english note names.

That's why I wanted to show it to you, and copied it to Frogs. Thanks for
giving me a good opportunity to put together a mini example. It'll go in
the CG somewhere, I suppose. Or maybe in the Learning Manual on Scheme

Good luck!
