Contrasting the experience of mortality in opera to that in tragedy, the Hutcheons find a more apt analogy in the medieval custom of "contemplatio mortis"--a dramatized exercise in imagining one's own death that prepared one for the inevitable end and helped one enjoy the life that remained. From the perspective of a contemporary audience, they explore concepts of mortality embodied in both the common and the more obscure operatic repertoire: the terror of death (in Poulenc's "Dialogues of the Carmelites"); the longing for death (in Wagner's "Tristan and Isolde"); preparation for the good death (in Wagner's "Ring of the Nibelung"); and suicide (in Puccini's "Madama Butterfly"). In works by Janacek, Ullmann, Berg, and Britten, among others, the Hutcheons examine how death is made to feel logical and even right morally, psychologically, and artistically--how, in the art of opera, we rehearse death in order to give life meaning.
