Mindy Aloff’s new book Why Dance Matters is part of a series, published by Yale University Press, on why this or that thing should matter to the reader. The series has already taken on such subjects as architecture, translation, poetry, and acting. And as of next January, it will include Aloff’s meditation on the many ways dance enters and alters our lives. At different points in her career, Aloff has been a poet, a dance critic, an essayist, a teacher, the editor of the anthology Dance in America, and the author of Hippo in a Tutu: Dancing in Disney Animation. She has spent her life looking at dance and thinking about what it means—how it interconnects with music, visual art, the movies, life.
