Around 1777, the 21-year-old
Wolfgang Amadeus Mozart spent some time in Mannheim, where he had hoped (in vain, it turned out) to find employment. Mozart undertook to teach Aloysia in singing. This is less implausible than it might seem, since according to
Mahling, Mozart was himself a trained (former) soprano, instructed in childhood (1764–1765) by a celebrated
castrato,
Giovanni Manzuoli. Mozart had performed in public as a singer repeatedly up until he was 13, after which perhaps puberty proved a barrier to further performances. Mozart was also an experienced composer of operas, familiar with all aspects of opera production from his journeys to
Italy. At the time of this instruction, Aloysia was already a very advanced pupil. Mozart felt that she already commanded an excellent
cantabile style but felt she could use some work on highly virtuosic passages of rapid notes. He wrote to his father: [Mlle Weber] sings from her heart and most likes singing cantabile. I have brought her through the
grand aria to the passages, because it is necessary when she comes to Italy for her to sing bravura arias. She will certainly not forget cantabile, because that is her natural inclination. To achieve this end, Mozart taught Aloysia to sing a number of arias that included bravura passages, taken from his earlier work in Italy. By Mozart's own account, Aloysia was a very fine pupil, and at the end of the instruction period he wrote a kind of examination piece, the recitative and aria
K. 294 "Alcandro, lo confesso/Non sò, d'onde viene". As Mozart wrote to his father: When I had it ready, I said to Mlle Weber: learn the aria yourself, sing it as you wish; then let me hear it and I will tell you honestly what I like and what I don't like. After two days, I came and she sang it to me, accompanying herself. Then I was obliged to admit that she had sung it exactly as I had wanted it and as I would have taught it to her myself. That is now the best aria she has; with it she certainly brings credit on herself wherever she goes. In the course of all this instruction Mozart fell in love with Mlle Weber. He expressed a desire to marry her, though it is not clear exactly how serious his intentions were, or whether they were reciprocated. Mozart left Mannheim for several months for Paris on an unsuccessful job search. On his way back to Salzburg, he passed through Munich, where the increasingly-successful Aloysia was by now employed. According to the tale told in
Georg Nikolaus von Nissen's draft biography of Mozart, Mozart and Aloysia had a somewhat unpleasant encounter: When he entered, she appeared no longer to know him, for whom she previously had wept. Accordingly, he sat down at the piano and sang in a loud voice, "" (The one who doesn't want me can lick my arse). The vulgar phrase in Mozart's song corresponds to the English idiom "kiss my ass", and occurs frequently in Mozart's letters; see
Mozart and scatology. Mozart himself moved to Vienna in 1781, and later that year was for a time a lodger in the Weber home. The father Fridolin had died in 1779, and Aloysia's mother
Cäcilia Weber was taking in boarders to make ends meet. Mozart fell in love with the third daughter, Constanze. When the two married in 1782, Mozart became Aloysia's brother-in-law. Apparently there were no long-term hard feelings, as Mozart wrote a fair amount of additional music for Aloysia to sing, listed below.
Music written by Mozart for Aloysia Weber From the Mannheim visit: • Recitative and Aria for Soprano, "",
K. 294) • Recitative and Aria for Soprano, "
Popoli di Tessaglia!", K. 316/300b. This has a
range up to
G, which earned it a listing in
Guinness lists as the highest demanded note in the classical repertoire. From the Vienna years: • Aria for Soprano, "", K. 383 of
Pasquale Anfossi's opera
Il curioso indiscreto. These were "
Vorrei spiegarvi, oh Dio!" K. 418 and "" K. 419. • The role of Mme. Herz in the short
singspiel Der Schauspieldirektor K. 486, consisting of one aria "Da schlägt die Abschiedsstunde", a trio, and the vaudeville finale. This occasional piece was written for an elaborate party given by the
Emperor Joseph II in February 1786. • Aria for Soprano, "", K. 538. This work has an unusual history, which has been worked out using handwriting analysis from
Wolfgang Plath and watermark analysis from
Alan Tyson. There exists a
particella score (voice and bass line only) from 1778, written when Mozart was in love with Aloysia, and a complete score, dedicated to the now-married "Signora Lange", from 1788. Tyson writes (1990:233) "there was no real dishonesty in describing it almost ten years later as "per la Sigra Lange" -- it was still the same voice, though the singer had changed her name."
