[Harry Potter] Why doesn’t Hogwarts have an Arts Department?

All of the courses at Hogwarts seem to be practical and functional. **Defense Against the Dark Arts**, **Transfiguration**, **Potions**, and such. I’m aware that, in the movies, there appears to be a choir, but it seems that’s less of a class and more of an extracurricular; plus, it’s only seen in one or two scenes.

Why doesn’t Hogwarts have classes in **Photography** (which is closer to Muggle Filmography than Photography), **Dance**, or **Creative Writing**?

Hogwarts is a vocational school. The purpose of the school is to teach you to be a competent wizard (but not TOO competent, hence the Restricted Section). 

You have freedom in what classes you choose, but ultimately if it won’t help you be a wizard it’s not worth teaching.
