Ein deutsches Requiem, nach Worten der heiligen Schrift, Op. 45

​Johannes Brahms’ “A German Requiem, to Words of the Holy Scriptures,” is a large-scale work for chorus, orchestra, and soprano and baritone soloists. It was composed between 1865 and 1868, comprising seven movements, making it Brahm’s longest composition at 80 minutes. Although it is sacred, with 25 direct Biblical texts from the German Luther Bible, it is unlike the more traditional liturgical Latin Requiems. Its focus is on the living beginning with the text from the Beatitudes, transiting from anxiety to comfort; implying that the source of our comfort is the Lord. Brahms assembled the libretto himself.
