Christus factus est, WAB 11

 ("Christ became obedient"), WAB 11, is a sacred motet by Anton Bruckner, his third setting of the Latin gradual "Christus factus est", composed in 1884. Before, Bruckner composed in 1844 a first piece on the same text as gradual of the "Messe für den Gründonnerstag" (WAB 9), and in 1873 a motet (WAB 10) for eight-part mixed choir, three trombones, and string instruments "ad libitum". The motet is an expressive setting of the gradual, influenced by Wagner's music.
History.
Bruckner composed this motet, which uses the gradual of Maundy Thursday, on 25 May 1884. The piece was performed six months later, on 9 November, in the "Wiener Hofmusikkapelle". Bruckner dedicated the work to Oddo Loidol, one of his students.
The original manuscript is in a private collection (Dr Wilhelm, Bottmingen), but transcriptions of it are found in the archives of the Abbey of Kremsmünster and the Austrian National Library. The piece was published together with three other graduals (', WAB 23, ', WAB 30, and ', WAB 52) by Theodor Rättig, Vienna in 1886. The motet was published in volume XXI/30 of the '.
Music.
The work in 79 bars in D minor is set for mixed choir "a cappella". It takes about five minutes to perform.
In the first part (bars 1–19), till "mortem autem crucis", the choir is singing in homophony. It expresses in sombre lines how inhuman is God's demand to implacable obedience to the death, even the death on the cross. After a one-bar rest (bar 20), the motet evolves in waves of intensification, with twice the ", on "exaltavit illum" (bars 23–24) and "super omne nomen"" (bars 37–38), respectively. After a second one-bar rest (bar 56) it reaches a dramatic climax (bars 57–62). Thereafter the motet is evolving "diminuendo" and a gradual sorrowful rest returns with the 8-bar coda in "pianissimo", which is harmonically similar to that of the previous setting of 1873. Publisher Carus-Verlag summarizes that by means of modulation and chromatic, Bruckner achieves heightened expressiveness for the Passion text.
Bruckner composed the piece when he was in preparation to have his Symphony No. 7 performed and revised his "Te Deum". The second part of the Grail motif from Wagner's "Parsifal" which the composer had heard in Bayreuth in 1882 is also the "Dresdner Amen".
