"'When was the score of the Requiem completed?' is a question that everyone has asked; . . .but Wolff goes on to ask: 'Where do the technical and stylistic premises for the Requiem lie, and to what extent could these be taken into account after Mozart's death?' This question is rich in implications, central to the uniqueness of the work, and virtually undiscussed in the Mozart literature."—Thomas Bauman, co-author of Mozart's Operas
