This newly edited version of Mozart's Requiem (K.626) matches up this piano vocal score with a new set of orchestra parts (available separately). Previous versions of this work by other publishers are traditionally littered with mistakes and wrong notes / instructions / inconsistent dynamics, which have been fixed in this edition, including the addition of rehearsal marks which correspond with the conductor score and orchestra parts. Mozart's 1791 work (completed by Süssmayr in 1792) comprises fourteen movements in eight sections: I. Introitus: Requiem aeternam (Chorus and solo Soprano), II. Kyrie (Chorus), III. Sequenz: 1. Dies irae (Chorus), 2. Tuba mirum (four soloists: Soprano, Alto, Tenor and Bass), 3. Rex tremendae (Chorus), 4. Recordare (Chorus), 5. Confutatis (Chorus), 6. Lacrimosa (Chorus), IV. Offertorium: 1. Domine Jesu (Chorus with Soprano, Alto, Tenor and Bass soloists), 2. Hostias (Chorus), V. Sanctus (Chorus), VI. Benedictus (Soprano, Alto, Tenor and Bass soloists with Chorus), VII. Agnus Dei (Chorus) and VIII. Communio: Lux aeterna (Soprano solo with Chorus).

It has become one of the most popular works for choirs throughout the world, and notably features the ever popular choral piece, 'Lacrimosa'. This is frequently a major study work at conservatoires and universities. This new edition is for chorus, soloists and piano.
