My theory III teacher in college was a very clever, unconventional guy. He knew theory IV, where we would learn about scary, scary 12-tone serialism, was on the horizon. To make sure we got the ground work for that course solidly, he taught the entire theory III class out of The Beatles song book. It was an enormously fun class that made a complex subject of not-exactly-tonal music theory fun (it would’ve been fun for me either way, I tend to care more about how cool the placement of notes is as opposed to how they sound).
