No other work by Mozart is so enshrouded in myth as his final composition, the D-minor Requiem. Mozart died before its completion, and the missing sections had to be added by others. The many handwritten copies circulated after his death added to the corruption of the text by contributing errors of their own. Now Peters is publishing a new urtext edition of this staple of the choral repertoire, edited by David Black. The edition relies on Mozart's composition and the traditional completion by Franz Xaver Süssmayr. For the first time, however, it incorporates sources previously unavailable to earlier editions, including the Neue Mozart-Ausgabe.
