Heard whispers open the play, repeating the words “Salieri” and “Assassin.” A seated man’s silhouette is seen with its back toward the audience. The man is Salieri, retired court composer to the Habsburg emperor Joseph II; he is sitting in his apartment in Vienna. Turning around in his wheelchair, he narrates a confession to the audience, asking it to be his confessor.

Salieri finds Mozart’s music as beautiful as he finds Mozart himself repulsive and childish. The girl is Constanze, whom Mozart marries against his authoritarian father’s will.
In court, Mozart also makes impromptu variations on one of Salieri’s vapid march themes, greatly enlivening the...
