This edition of Mozart's final work, the Requiem, starts afresh from Mozart's incomplete score, omitting the continuations and orchestrations by Joseph Eybler and Franz Xaver Süssmayr, who were engaged by Mozart's widow, Constanze, to complete the setting. The orchestration has been reworked throughout by Richard Maunder, and the 'Lacrymosa' has been given a new continuation. Süssmayr's Sanctus and Benedictus movements have been included as an appendix. The vocal score includes an orchestral reduction for rehearsal purposes, and full details of editorial emendations and additions can be found in the full score. Complete orchestral and vocal material is available on hire/rental, and the vocal score is also available on sale.
