Does anyone recognize this VIC-20 music program?

Does anyone recognize this as a VIC-20 demo program? It was on a tape surrounded by things I wrote, but I do not recall writing this:
https://github.com/allenhuffman/VIC-20/tree/main/music
The code looks like other programs I wrote, but since I was using things from the VIC-20 manual (variables for the tone POKEs) that doesn't help much.
