insisted on boy treble and alto choristers and soloists; Fauré composed the work with those voices in mind, and had to employ them for his performances at the Madeleine, but in the concert hall, unconstrained by ecclesiastical rules, he preferred female singers for the upper choral parts and the solo in the Pie Jesu. In 1899–1900, the score was reworked for full orchestra. This final version was premiered at the Trocadéro in Paris on 12 July 1900, during the Exposition Universelle. Paul Taffanel conducted forces of 250 performers. The composer said of the work, "Everything I managed to entertain by way of religious illusion I put into my Requiem, which moreover is dominated from beginning to end by a very human feeling of faith in eternal rest." He told an interviewer, In 1924 the Requiem, in its full orchestral version, was performed at Fauré's own funeral. It was not performed in the United States until 1931, at a student concert at the Curtis Institute of Music in Philadelphia. It was first performed in England in 1936. Text Most of the text is in Latin, except for the Kyrie which is Koine Greek. As had become customary, Fauré did not set the Gradual and Tract sections of the Mass. He followed a French Baroque tradition by not setting the Requiem sequence (the ), only its section . He slightly altered the texts of the Introit, the Kyrie, Pie Jesu, , and , but substantially changed the text of the Offertory (described below). He did not set the (the conclusion of the ), and added two texts from the Order of Burial, and In Paradisum. Fauré made changes to the text of the Offertory; at the beginning, he adds an "O". He changed "" ("deliver the souls of all the faithful departed") to simply "" ("deliver the souls of the departed"). He replaced "" ("Deliver them") at the beginning of the next verse with a repetition of "", and he omitted the third verse (beginning ""). He concludes with an added "Amen". Structure and scoring The composition is structured in seven movements: The piece has a duration of about 35 minutes. Fauré scored the work for two soloists, chorus and orchestra. Its movements and their sections are listed in a table for the scoring in voices, key, time signature (using the symbol for common time, equivalent to ) and tempo marking. The
