This is the story of a great musical genius who was a prodigy performer at the age of six and a composer at the age of seven. As a little boy, dressed in court style, he made his debut in Vienna. All his life he was something of a child and consequently his career has always had a peculiar fascination for children. In this book the authors and the illustrator have caught that elusive child-like spirit of Mozart which will delight children and grown-up readers as well. From the dust jacket.

Mozart's childhood, his almost super-natural development as composer and player, his great personal charm, his idealistic innocence, his whole world are portrayed by the authors and the artist in lively text and enchanting pictures. In this all-encompassing book, now a beloved classic, thirty-five full pages of Mozart's music are included at the special request of a host of young readers.
