"Anthony Hecht's vast knowledge of literature and his gift for mesmerizing argument are both amply present in Melodies Unheard. Whether defending the sestina against accusations of boredom and dolefulness or examining the structure of Shakespeare's sonnets or unraveling some of the complexity of Moby-Dick, these essays are models of civility, candor, and grace. I know of no other poet, certainly none of Anthony Hecht's stature, who sheds as much light on the intricacies and hidden designs of poems and who does it with such style."
