In the stage play and film Amadeus, the composer Antonio Salieri is portrayed as envious of the young Mozartâs genius to the point of murder. But Amadeus the play and the film were not the first dramatic works to take up the theme of Salieriâs envy. An earlier work far less well known to us today was Rimsky-Korsakovâs opera Mozart and Salieri, based on Pushkinâs drama of the same name. The opera unfolds a dialogue between the two title characters, covering various moments in their relationship, leading up to the end, when Mozart lies dying from poisoning, implicitly at Salieriâs hands. In one of the operaâs episodes, Mozart improvises at the keyboard; in another he tells Salieri the story of the mysterious man in black who commissioned him to compose a Requiem. Of course, opera being opera, the Mozart character had to die in Rimskyâs opera.  But in the final scenes, thereâs still a place for Mozartâs immortal music.
