I really like tiny rabbit's suggestion to just make stuff up. No need to reveal yourself in this class. You can still find your musical voice through creativity and evasion. No one has a right to pry so just play the game. You may be surprised at what this inspires.

In art school, we had a few assignments that were just a bit too revealing. I remember making some sh**t up at the last minute, highly abstract --not at all my style (I'm actually a pretty realistic illustrator) in regards to my family. A got an A and I was relieved but a bit disgusted that lying got me a better grade. But it was an interesting experiment
