Just claim a major at the outset, even if you aren't completely interested in it. Changing within a faculty is a simple process, so when you do find what you want, it isn't hard. Just take the courses that interest you, and work from there.

Come away, O human child!
To the waters and the wild
With a faery, hand in hand,
For the world's more full of weeping than you can understand.
