The circumstances of his death have attracted much research and speculation. Some principal sources of contention are as follows. Mozart scholarship long followed the accounts of early biographers, which proceeded in large part from the recorded memories of his widow Constanze and her sister Sophie Weber as they were recorded in the biographies by Franz Niemetschek and Georg Nikolaus von Nissen. For instance, the important biography by Hermann Abert (1923/2008:1305-9) largely follows this account. The following is a summary of
Wolfgang Amadeus Mozart Theme from Mozart's Opera "Die Zauberflöte" (1822), Frédéric Chopin's Variations on "Là ci darem la mano" from "Don Giovanni" (1827), and Max Reger's Variations and Fugue on a Theme by Mozart (1914), based on the variation theme in the piano sonata K. 331; Pyotr Ilyich Tchaikovsky wrote his Orchestral Suite No. 4 in G, "Mozartiana" (1887), as a tribute to Mozart. For unambiguous identification of works by Mozart, a "Köchel catalogue number" is used. This is a unique number assigned, in regular chronological order, to every one of his known works. A work is referenced by the abbreviation "K." or
