Maria Anna Thekla Mozart Maria Anna Thekla Mozart Maria Anna Thekla Mozart (September 25, 1758 – January 25, 1841), called "Marianne", known as Bäsle ("little cousin"), was the cousin of Wolfgang Amadeus Mozart. She was born in Augsburg, Germany, the third (and only surviving one) of five daughters of Franz Alois Mozart, a younger brother of Leopold Mozart and Maria Victoria Eschenbach. Between October 11 and October 26, 1777, 19-year-old Marianne met the 21-year-old Wolfgang in Augsburg. The young people developed a close, probably intimate relationship. Ten letters of their subsequent correspondence have been preserved, all from Wolfgang to Marianne. These are called the
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
