context_page_description: The Requiem in D minor, K. 626, is a requiem mass by Wolfgang Amadeus Mozart. Mozart composed part of the Requiem in Vienna in late 1791, but it was unfinished at his death on 5 December the same year. A completed version dated 1792 by Franz Xaver Süssmayr was delivered to Count Franz von Walsegg, who commissioned the piece for a requiem service to commemorate the anniversary of his wife's death on 14 February.
  The autograph manuscript shows the finished and orchestrated Introit in Mozart's hand, and detailed drafts of the Kyrie and the sequence Dies irae as far as the first eight bars of the Lacrymosa movement, and the Offertory. It cannot be shown to what extent Süssmayr may have depended on now lost "scraps of paper" for the remainder; he later claimed the Sanctus and Benedictus and the Agnus Dei as his own.
  Walsegg probably intended to pass the Requiem off as his own composition, as he is known to have done with other works. This plan was frustrated by a public benefit performance for Mozart's widow Constanze.
context_section_description: Süssmayr's completion divides the Requiem into eight sections:
  Introitus
  Requiem aeternam
  Kyrie
  Sequentia (text based on sections of the Dies irae)
  Dies irae
  Tuba mirum
  Rex tremendae
  Recordare
  Confutatis
  Lacrymosa
  Offertorium
  Domine Jesu
  Hostias
  Sanctus
  Benedictus
  Agnus Dei
  Communio
  Lux aeterna
  Cum sanctis tuis
  All sections from the Sanctus onwards are not present in Mozart's manuscript fragment. Mozart may have intended to include the Amen fugue at the end of the Sequentia, but Süssmayr did not do so in his completion.
  The following table shows for the eight sections in Süssmayr's completion with their subdivisions: the title, vocal parts (solo soprano (S), alto (A), tenor (T) and bass (B) [in bold] and four-part choir SATB), tempo, key, and meter.
