Program Doodle

Last Sunday, I went to three performances for class credit. In one of them, I had a big program and some pencils, and the performer was behind us, so...I decided to start doodling something abstractish.

This is the symbol for the Music element in Wildale Glades, if you can see it. It's not that great, since it's a doodle, but you might notice I colored the note differently than the other stuff. Took a few classes to finish it.

If anyone knows the name of this technique, tell me, please
