Prop ideas for a senior portrait session?

I'm doing my first senior portrait shoot today, and I'm trying to get some last minute prop ideas to offer. When she asked about props, I asked what she liked to do, or did in school. The only things that we got together were her flag (she's a flag twirler for band), and that she loves reading and listening to music. I'm trying to come up with some ideas with those two, but sort of failing.
