Morpugro, Michael (2008). The Mozart Question. Grades 4-6.
Paolo Levi is a world-renowned violinist with a secret that no one has attempted or dared to uncover. When Lesley, a journalist, is scheduled to interview Levi, she is told not to ask the "Mozart question." What is the "Mozart question" she wonders? Lesley's interview question prompts Levi to recall how as a boy he developed his passion for the violin after his mother showed him a hidden violin belonging to his father. He would secretly borrow the violin and sneak out for lessons with a man who had once known Levi's parents and the secret they kept hidden all these years from their son. Beautiful watercolor illustrations are interspersed throughout the book.
