DESCRIPTION:
The Requiem Mass in D minor (K. 626) by Wolfgang Amadeus Mozart was composed in Vienna in 1791 and left unfinished at the composer's death. A completion by Franz Xaver Süssmayr was delivered to Count Franz von Walsegg, who had anonymously commissioned the piece for a requiem Mass to commemorate the February 14 anniversary of his wife's death.
It is one of the most enigmatic pieces of music ever composed, mostly because of the myths and controversies surrounding it, especially around how much of the piece was completed by Mozart before his death. The autograph manuscript shows the finished and orchestrated introit in Mozart's hand, as well as detailed drafts of the Kyrie and the sequence Dies Irae as far as the first nine bars of "Lacrimosa", 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 Agnus 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. A modern contribution to the mythology is Peter Shaffer's 1979 play Amadeus, in which the mysterious messenger with the commission is the masked Antonio Salieri who intends to claim authorship for himself.
The Requiem is scored for 2 basset horns in F, 2 bassoons, 2 trumpets in D, 3 trombones (alto, tenor & bass), timpani (2 drums), violins, viola and basso continuo (cello, double bass, and organ). The vocal forces include soprano, contralto, tenor, and bass soloists and a SATB mixed choir. At the time of Mozart's death on 5 December 1791, only the opening movement (Requiem aeternam) was completed in all of the orchestral and vocal parts. The following Kyrie and most of the sequence (from Dies Irae to Confutatis) were complete only in the vocal parts and the continuo (the figured organ bass), though occasionally some of the prominent orchestral parts were briefly indicated, such as the violin part of the Confutatis and the musical bridges in the Recordare. The last movement of the sequence, the Lacrimosa, breaks off after only eight bars and was unfinished. The following two movements of the Offertorium were again partially done; the Domine Jesu Christe in the vocal parts and continuo (up until the fugue, which contains some indications of the violin part) and the Hostias in the vocal parts only. The Sussmayr completion of the Requiem is divided into fourteen movements, with the following structure:
I. Introitus: Requiem aeternam (choir and soprano solo)
II. Kyrie eleison (choir)
III. Sequentia (text based on sections of the Dies Irae):
-Dies irae (choir)
-Tuba mirum (soprano, contralto, tenor and bass solo)
-Rex tremendae majestatis (choir)
-Recordare, Jesu pie (soprano, contralto, tenor and bass solo)
-Confutatis maledictis (choir)
-Lacrimosa dies illa (choir)
IV. Offertorium:
-Domine Jesu Christe (choir with solo quartet)
-Versus: Hostias et preces (choir)
V. Sanctus:
-Sanctus Dominus Deus Sabaoth (choir)
-Benedictus (solo quartet, then choir)
VI. Agnus Dei (choir)
VII. Communio:
-Lux aeterna (soprano solo and choir)
Mozart esteemed Handel and in 1789 he was commissioned by Baron Gottfried van Swieten to rearrange Messiah. This work likely influenced the composition of Mozart's Requiem; the Kyrie is probably based on the And with his stripes we are healed chorus from Handel's Messiah (HWV 56), since the fugato, in which Handel was a master, is the same, with only slight variations by adding ornaments on melismata.
Some believe that the Introitus was inspired by Handel's Funeral Anthem for Queen Caroline (HWV 264), and some have also remarked that the Confutatis may have been inspired by Sinfonia Venezia by Pasquale Anfossi. Another possible influence may be Michael Haydn's Requiem in C minor; as the Introitus sounds rather similar to Mozart's.
