The Mozart family grand tour began, presenting child prodigies Maria Anna and Wolfgang in Western Europe.

The Mozart family grand tour was a journey through western Europe, undertaken by Leopold Mozart, his wife Anna Maria, and their children Maria Anna (Nannerl) and Wolfgang Theophilus (Wolferl) from 1763 to 1766. At the start of the tour the children were aged eleven and seven respectively. Their extraordinary skills had been demonstrated during a visit to Vienna in 1762, when they had played before the Empress Maria Theresa at the Imperial Court. Sensing the social and pecuniary opportunities that might accrue from a prolonged trip embracing the capitals and main cultural centres of Europe, Leopold obtained an extended leave of absence from his post as deputy Kapellmeister to the Prince-Archbishopric of Salzburg. Throughout the subsequent tour, the children's Wunderkind status was confirmed as their precocious performances consistently amazed and gratified their audiences.

Maria Anna Walburga Ignatia "Marianne" Mozart, nicknamed Nannerl, was a highly regarded musician from Salzburg, Austria. In her childhood, she developed into an outstanding keyboard player under the tutelage of her father Leopold. She became a celebrated child prodigy and went on concert tours through much of Europe with her parents and her younger brother Wolfgang Amadeus Mozart. At age 17, her career as a touring musician came to an end, though she continued to work at home teaching piano and performing on occasion. At age 33 she married, moved to a village six hours by carriage from Salzburg, and there raised her own and her husband's children. On her widowhood in 1801, she returned to Salzburg and resumed teaching and performance. She is known to have composed works of music, though no manuscripts survive. In her later years she contributed to the biographical study of her late brother.

Wolfgang Amadeus Mozart was a prolific and influential composer of the Classical period. Despite his short life, his rapid pace of composition and proficiency from an early age resulted in more than 800 works representing virtually every Western classical genre of his time. Many of these compositions are acknowledged as pinnacles of the symphonic, concertante, chamber, operatic, and choral repertoires. Mozart is widely regarded as one of the greatest composers in the history of Western music, with his music admired for its "melodic beauty, its formal elegance and its richness of harmony and texture".
