We all know that the Hogwarts curriculum ((and thus most likely the average curriculum at most wizarding schools)) consists of 12 classes. Astronomy, Arithmancy, Ancient Runes, Charms, Potions, Herbology, Transfiguration, Defense Against the Dark Arts, Divination, History of Magic, Care of Magical Creatures, and Muggle Studies.
But whose to say those are the only classes ever taught? Any other ideas for classes? These are a few I've come up with:
Literature- C'mon now! Who doesn't want to hear all the classics ((Just make sure not to get Hagrid and Slughorn started on 'Odo the Hero')) ? I can't imagine that all the books in Hogwart's great library are non-fiction.
Musical Arts- In the movies we see a school choir ((toads and all)), and in the the books we are introduced to a school song ((strike up your favorite tune!)). So why not a 'musical arts' class? Similar to 'band' classes in the states. Covering note reading, tuning, a bit of musical history, your instrument of choice ect...
Foreign and Ancient Languages- Well if Barty Crouch could do it, why not students? French ((mightve come in handy during GoF)), Bulgarian, Gaelic, Latin, Greek, ect...
