The Mozart family grand tour was a journey through western Europe, undertaken by Leopold Mozart, his wife Anna Maria, and their musically gifted 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.

Johann Georg Leopold Mozart was a German composer, violinist, and theorist. He is best known today as the father and teacher of Wolfgang Amadeus Mozart, and for his violin textbook Versuch einer gründlichen Violinschule (1756).
