After the heated confrontation with Marioni, Matteo runs away and goes to the director who shows understanding and suggests that the boy no longer be part of the orchestra. Matteo says he will manage and find another way to vent.

While Barbara is recommended a book about music that she might like, Matteo is encouraged to not follow the rules and keep laughing.

The kids get together to practice all together as instructed by Marioni. However, when they start talking about themselves, they lose the desire to play and change their plans.
