While Chiara and Robbo explore their secret place, the father returns and suggests that they cook together. Clelia and Roberto hope to obtain permanent custody of Rosario, and Barbara's mother is happy with her daughter's results and wants to reward her.

Barbara is reprimanded because she appears tense and seems to never have fun. She maintains that she's not there to have fun and that in any case, she manages to do everything. Robbo and Chiara are at home since they're not feeling too well.

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

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.

Maestro Marioni asks Matteo what he wants to do with his life in music and is not satisfied with the answer he receives. The teacher, with his passionate tone, urges Matteo and encourages him not only to try but to do something more.

Sara is about to accompany Matteo on a tour of the facility when they run into Gigi, who asks for explanations about the girl's behavior. While they continue the tour, Marioni calls Matteo for an early violin lesson.

A chaotic day in an Italian classroom: amid grammatical difficulties, unexpected incidents, and group dynamics, tensions, irony, and solidarity intertwine between students and teachers.

Sofia goes up to the roof to practice her cello, but ends up singing a song (in English). When Maestro Marioni gets home from an amorous encounter, he watches a video where Matteo's previous violin teacher introduces him and explains his special situation.

Sofia is practicing cello when her brother asks her for a favor. His girlfriend Ilaria comments on Sofia's weight.

Sara is home at dinner arguing with her mother who finds her unbearable. Sara's phone rings with an audio cue indicating the caller. Robbo and his sister Chiara are going home on the tram when, out the window, they see someone they think they recognize.

Barbara is practicing piano in the presence of her mother, who tries to encourage her. Little by little Barbara manages to focus on the music, and perhaps not only the music. Another pianist is playing the same piece in a music store. He might be there because he has no piano at home.

Matteo is at home with his uncle, doing a tricky jigsaw puzzle and ready for dinner. Even though it is clear to Matteo that his uncle is gay, his uncle is very uncomfortable talking about it. Matteo lets his uncle know that there is a girl he likes.

A colleague of Marioni's chides him for having treated Matteo as he did. He tries to justify his actions, and then goes to have a word with Rosario, a percussion student.

Marioni puts Matteo to the test, asking him to play first violin in the Brahms symphony, together with the entire orchestra. Later, Domenico tells him about someone who had crumbled under Marioni's harsh treatment.
