original question: [Nigredo Hotel] belongs to which opera genre?
answer: chamber opera
answer type: Opera Genre.
auxiliary information: Nigredo Hotel is a chamber opera in one act composed by Nic Gotham to a libretto by Ann-Marie MacDonald. It premiered on 13 May 1992 at the Tarragon Theatre in Toronto in a production by Tapestry New Opera Works who had commissioned the opera. The production won two Dora Awards and the work was nominated for the Floyd S. Chalmers Canadian Play Award. Subtitled "an operatic thriller", it is set in Room 7 of a run-down hotel which takes its name from the Jungian concept of Nigredo or "dark night of the soul". The story involves an encounter between the beautiful but crazed woman who runs the hotel and a brain surgeon forced to take refuge there after crashing his car.
