Indeed, that's much better and produces point-and-click *at all*. And
especially it looks much more expandable once I might want to add more
bells and whistles to the generated music.

How would I find out about that solution? What I came up with was the
result of taking \displayMusic's result as a model.

Concretely: Can you tell me what the "#@" in front of (color-music does?
