Who really commissioned Mozart’s
Requiem, and who actually wrote it?
What a fantastically complicated story lies behind these two simple questions! All sorts of theories have been suggested: that Mozart thought the commission had come from the Underworld and that he was writing his own funeral music, that Antonio Salieri, Mozart’s musical rival, was behind the commission (and also behind Mozart’s death), and so on. We do have an actual anecdote, mentioned in several reputable Mozart biographies, that Mozart told his wife, Constanze, that he was thinking of death and didn’t believe he had much longer to live, that he felt that he was writing the requiem for himself, and that he was sure he had been poisoned. So Constanze took the score away from him for awhile until his spirits lifted. We have no concrete evidence that a) Mozart actually said this or b) he was actually being poisoned. Indeed, while there have been over 100 theories proposed as to the cause of his death, the most credible idea is that he died of a recurrence of rheumatic fever, a disease he had first contracted as a child.
