Giuseppe Verdi’s last two operas, the Shakespearean diptych of Otello and Falstaff, together constitute my favorite case study in what happens when a play is made to stand up and sing. Both the source material and the musical adaptations are works of singular beauty and power. To study these operas alongside their sources is to see what is gained and what is lost, what remains intact and what is transformed, when a complex human drama is adapted from speech into song. – New York Review of Books
