Scene 1
Salieri enjoys high social position as a composer, and has dedicated himself to the service of his art. Secretly, however, he is jealous of Mozart's works because he recognizes their superior quality, especially given what he sees as the "idle" character of Mozart. Salieri invites Mozart to dinner and plans to poison him.
Scene 2
Mozart and Salieri are dining at an inn. Mozart is troubled by his work on his Requiem, which a stranger in black commissioned from him. Mozart recalls Salieri's collaboration with Pierre Beaumarchais and asks if it could be true that Beaumarchais once poisoned someone, for genius and criminality are surely incompatible. Salieri then surreptitiously pours poison into Mozart's drink. Mozart begins to play at the keyboard, as Salieri begins to cry. Mozart sees this, but Salieri urges Mozart to continue. Mozart begins to feel ill, and leaves. Salieri ends the opera pondering Mozart's belief that a genius could not murder: did not Michelangelo kill for his commissions at the Vatican, or were those idle rumours?
