In July 1765, in a London tavern with the inviting name the Swan and Harp, in Cornhill, a district not far from St. Paul’s Cathedral, Leopold Mozart presented his two children, Maria Anna, called Marianne or Nannerl (who was fourteen) and WOLFGANG (who was nine) to the public.
The article did say that "As he approached the age of ten he was less stupefying than he had been four years earlier, when he played in Vienna before Empress Maria Theresa. This was precisely why his father, after exploiting wealthier circuits, decided to peddle him at a discount price in a tavern."
In a flier written by their father the two children were presented as “Prodigies of Nature.” Both children played the harpsichord well, but little Wolfgang was astonishing.

Until 1773 Wolfgang was completely under the direction of his father. He did not go to school. Wolfgang was a child prodigy and his father sought to develop that great musical talent.

In 1782, Mozart started a new life. He got married to Constance Weber in August 1782.
