 Mozart discovered that his two children were musically gifted in about 1759, when he began with keyboard lessons for the seven-year-old Nannerl.The toddler Wolfgang immediately began imitating his sister, at first picking out thirds on the keyboard and then making rapid progress under Leopold's instruction.By 1762, the children were ready to work as concert performers, and Leopold began taking the family on extensive concert tours, performing for both aristocracy and public, throughout central and western Europe.
