Morgen und Abend is Georg Friedrich Haas's seventh opera, a co-commission by the Royal Opera in London and Deutsche Opera in Berlin. It is an hour-and-a-half long, and its libretto is adapted from the novel Morgon og Kveld (2000) by Norwegian author Jon Fosse, whose work Haas previously adapted in Melancholia for the Paris Opéra. Morgen und Abend's two continuous scenes present the life of fisherman Johannes by focusing on its two most salient moments – Johannes's birth (in the morning) and death (in the evening). In this strategy there is a slight, if inadvertent, echo of the lights on/lights off of Haas's In Vain.
