Of her two older sisters the second, Aloysia, had a beautiful voice and no mean looks, and the young genius was greatly taken with her from the first.  He induced his mother to linger in Mannheim much longer than was necessary.  Aloysia became his pupil; and under his tuition her voice improved wonderfully.  She achieved brilliant success in public, and her father, delighted, watched with pleasure the sentimental attachment that was springing up between her and Mozart.  Meanwhile Leopold Mozart was in Salzburg wondering why his wife and son were so long delaying their further journey to Paris.

When he received from Wolfgang letters full of enthusiasm over his pupil, coupled with a proposal that instead of going to Paris, he and his mother should change their destination to Italy and take the Weber family along, in order that Aloysia might further develop her talents there, he got an inkling of the true state of affairs and was furious.  He had large plans for his son, knew Weber to be shiftless and the family poor, and concluded that, for their own advantage, they were endeavoring to trap Wolfgang into a matrimonial alliance.  Peremptory letters sent wife and son on their way to Paris, and the elder Mozart was greatly relieved when he knew them safely beyond the confines of Mannheim.

Mozart’s stay in Paris was tragically brought to an end by his mother’s death.  He set out for his return to Salzburg, intending, however, to stop at Mannheim, for he still remembered Aloysia affectionately.  Finding that the Weber family had moved to Munich, he went there.  But as soon as he came into the presence of the beautiful young singer her manner showed that her feelings toward him had cooled.  Thereupon, his ardor was likewise chilled, and he continued on his way to Salzburg, where he arrived, much to his father’s relief, still “unattached.”

When Mozart departed from Munich, he probably thought that he was leaving behind him forever, not only the fickle Aloysia, but the rest of the Weber family as well.  How slight our premonition of fate!  For, if ever the inscrutable ways of Providence brought two people together, those two were Mozart and Constance Weber.  Nor was Aloysia without further influence on his career.  She married an actor named Lange, with whom she went to Vienna, where she became a singer at the opera.  There Mozart composed for her the role of Constance in his opera, “The Elopement from the Seraglio.”  For the eldest Weber girl, Josepha, who had a high, flexible soprano, he wrote one of his most brilliant roles, that of the Queen of the Night in “The Magic Flute.”  I am anticipating somewhat in the order of events that I may correct an erroneous impression regarding Mozart’s marriage, which I find frequently obtains.  He composed the role of Constance for Aloysia shortly
