Traditional requiem texts, among them the anonymous medieval Latin poem Dies Irae (_Day of Wrath_), have inspired an untold number of composers in different ages and serving different religions, Western and Eastern. This book, the first comprehensive survey of requiem music for nearly half a century, provides a great deal of diverse and detailed information that will be of use to the professional musician, the musical scholar, the choral conductor, the theologian and liturgist, and the general reader.
