I wrote this mostly as an exercise in learning to use mup (which is music notation software that I highly recommend, you can get it
here). I sort of wanted to start off with a simple theme and see how wildly jazzy I could make it be by the end, and see if I could actually manage to notate it too.
I haven't written anything in like 20 years, just improvised stuff. It was fun.
This is definitely jazzy, not classical. Sorry if I'm putting it in the wrong forum, but it's also definitely a piano solo.
The .mid file is computer-generated, by mup. I also tried making my own, recording it in a sequencer (GarageBand), but I like mup's version much better. It's humiliating that a computer can play my own music better than me, but so it goes.
