During the orchestra rehearsal, a player makes a mistake and Marioni, the conductor, doesn't hesitate to press the point, in his usual cruel manner, that an orchestra is not a democracy.

Matteo seems fine but his father and uncle are worried about him. Marioni learns why Matteo is described as fragile and makes some decisions regarding the orchestra.

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.

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.

A teacher reads a passage from one of Shakespeare's sonnets and asks the class to interpret it. Matteo speaks up. Here is the original English: "Mark how one string, sweet husband to another,
Strikes each in each by mutual ordering;
Resembling sire and child and happy mother,
Who, all in one, one pleasing note do sing:
Whose speechless song being many, seeming one,
Sings this to thee: 'Thou single wilt prove none."

Matteo arrives late for class and is told, to sit next to Sara who begins asking him questions. It turns out she is almost blind. After the lesson, Matteo meets some of his classmates.

Matteo makes his way to his uncle's apartment. Never mind that his uncle was supposed to come to the station to get him... They agree that there is no point in worrying Matteo's father with the truth.
