Description
I can't figure out how to "iterate in musical time over the music tree".
After reading the documentation on ly.music, I cannot seem to decode what is meant by the phrase "Using the Music.events() method and the events module, it is possible to iterate in musical time over the music tree, e.g. to convert music to another format.". This is precisely what I want to do.
At first, I assume that Music.events refers to ly.music.Music.events(). Well, ly.music.Music.events() just calls ly.music.event.Events.traverse(), which itself seems to call ly.music.Music.events. This seems to be recursive. Why does ly.music.Music.events() take as parameters e, time, and scaling? What do they mean? Is e an ly.music.event.Events object? Because if so, I can't figure out what it's doing besides returning a number. It doesn't seem to be able to record anything about what it's traversing.
I would love to use this library to avoid reinventing the wheel, but I can't seem to figure out how it works from the documentation.
