Ludwig van Beethoven's life underwent an existential change when his brother died and left his son Karl in shared tutorship with his mother Johanna. 2. Almost without having had any relationship with his nephew, an intense and unexpected emotional need to become his sole guardian is triggered, an objective that he achieves by legally defeating his mother. 3. The Beethoven-Karl relationship develops plagued by disputes, surveillance, demands, control, as if the composer were experiencing for the first time what he had always denied himself, becoming a father.4. The nephew's suicide attempt points out to Beethoven that becoming a father means allowing the son to become different from the arrogant and inordinate personal ambitions and expectations, but this extreme signal was insufficient to make him understand that the other is always a danger because it shows a hidden and painful truth of one's own self.
