It’s a composition of the Star Wars Imperial March (the Vader theme) on Mario Paint. What’s that? Back in the early 1990s, Mario Paint was a Super Nintendo video game that used a computer-style mouse peripheral, and included a paint-shop-style artwork program and also a music composer. You couldn’t do a lot with it, really, and the sounds were all little Nintendo-ish blips and bleeps. You basically placed each note by hand to make short little compositions.
