The bell rang for the next class to begin, and the fifth graders walked into music class. Miss Crabapple stood with her back to the students as she wrote her name on the chalkboard. That was the first day of fifth grade with a grumpy teacher whom everyone feared. But as the school year progresses, the students learn to play beautiful music, and Miss Crabapple's stern side melts away. Based on the children's book by Betsy Cerulo.
