Libretto
The Requiem Mass in D minor (K. 626) by Wolfgang Amadeus Mozart was composed in Vienna in 1791, during the last year of the composer's life. The requiem was Mozart's last composition and is one of his most popular and respected works, although the question of how much of the music Mozart managed to complete before his death and how much was later composed by Franz Xaver Süssmayr or others is still debated.
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 or harpsichord). The vocal forces include soprano, alto, tenor, and bass soloists and an SATB mixed choir.
