Mozart- Dies Irae, from Requiem, K 626

This portion of Requiem is based off of a thirteenth-century Latin hymn attributed to either Thomas of Celano of the Franciscan Order (1200 -- c. 1265) or to Latino Malabranca Orsini (+1294), lector at the Dominican studium at Santa Sabina, the forerunner of the Pontifical University of Saint Thomas Aquinas, Angelicum in Rome.

AS SUNG-
"Dies irae, dies illa
Solvet saeclum in favilla,
teste David cum Sibylla.
Quantus tremor est futurus,
quando judex est venturus,
cuncta stricte discussurus!"

TRANSLATION-
"Day of wrath, day of anger
will dissolve the world in ashes,
as foretold by David and the Sibyl.
Great trembling there will be
when the Judge descends from heaven
to examine all things closely."

"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."
