Through close examination of the composer's birdsong cahiers they demonstrate how Messiaen translated nature into music in a way that had a major impact on his later work. They also consider issues of performance, and Messiaen's artistic relationship with his dedicatee and wife-to-be, Yvonne Loriod, including the significance of her two recordings of the cycle.
This book illuminates the Catalogue from a variety of angles: its historical significance, as a study of how mimicry of nature can be transformed into music of mesmeric originality, and as a guide that offers a wealth of fresh insights to listeners and performers.
