I'm in a class like that called IB Music Theory. Its not just theory though, its a lot of history of music and such. I'm lucky though, because they're onlye like 8 kids in the class. They're all very open minded, and love music as much as I do. It really has been a great class for me so far this year. Only piece we really didn't like (so far) was a symphony by Haydn. All the cadences were the same, and it got really annoying.
