Derrick and Melissa had been practicing for the last two weeks, but she still felt like they weren't ready. Their recital was on the 15th. They had both played in the school's band for the last two years. Melissa was a more experienced player.

All of the notes seemed to drift from her head like steam from a smokestack. She wondered if Derrick was as nervous. She thought about the crowd, and it made things worse.
