It was Tonal Harmony and Counterpoint. Unless you're at the specific college I went to, it wouldn't do you any good, but an equivalent course is offered at most universities and liberal arts colleges. FWIW I found it well worth it. My mom had been encouraging me to take something far outside my major (physics at the time, then I switched to CS), and was suggesting Art History. I couldn't make Art History work with my schedule, but I took this music theory class and it was great.
