Given the below context:  On 18 November 1763 the Mozart family arrived in Paris, one of the most important musical centres of Europe, and also a city of great power, wealth, and intellectual activity. Leopold hoped to be received by the court of Louis XV at nearby Versailles. However, a recent death in the royal family prevented any immediate invitation, so Leopold arranged other engagements. One person who took particular note of the children was the German diplomat Friedrich Melchior von Grimm, whose journal records Wolfgang's feats in glowing terms: "the most consummate Kapellmeister could not be more profound in the science of harmony and modulation". Leopold's own assessment, written a few months later, was similarly effusive: "My little girl, although only 12 years old, is one of the most skilful players in Europe and, in a word, my boy knows more in his eighth year than one would expect for a man of forty".On 24 December the family moved to Versailles for two weeks during which, through a court connection, they were able to attend a royal dinner, where Wolfgang was reportedly allowed to kiss the hand of the Queen. At Versailles they also visited the famous courtesan Madame de Pompadour, then in the last months of her life—"an extremely haughty woman who still ruled over everything", according to Leopold. In Nannerl's later recollections, Wolfgang was made to stand on a chair to be examined by the Madame, who would not allow him to kiss her.There is no record of the children giving a formal concert at Versailles. In February 1764 they were given 50 louis d'or (about 550 florins) and a gold snuff-box by the royal entertainments office, presumably for entertaining the royal family privately, but no more details are available. Further concerts were given in Paris on 10 March and on 9 April, at a private theatre in the rue et Porte St Honoré. At the same time Wolfgang's first published works were printed: two pairs of sonatas for harpsichord and violin, K. 6 and 7, and K. 8 and 9. These pairs became Opus 1 and Opus 2 in Leopold's...  Guess a valid title for it!
