The Mozarts at Schönbrunn
1762
On 13 October 1762 the ten-year-old Maria Anna and the six-year-old Wolfgang Mozart performed on the violin and clavier for the imperial family in the Hall of Mirrors at Schönbrunn Palace. Franz Stephan of Lorraine was enchanted with their performance and gave Wolfgang the task of playing with the keys covered up. The little boy not only accomplished this task but played a whole concerto by the court composer Wagenseil.
