Bruckner composed the motet in 1873, and it was first performed on 8 December 1873 in the Wiener Hofmusikkapelle for the celebration of Mariä Empfängnis (feast of the Immaculate Conception).[1]
The manuscript, a copy of which is archived at the Austrian National Library, was destroyed in 1945.[2] On his manuscript Bruckner wrote Besser ohne Violinen (better without violins).[1][3] According to R. Luna, this "would mean that he conceived the work ideally for eight-part choir with brief interventions of the trombones and that he had written the strings colla parte[4] to prevent any intonation problems.[5]
The work was published first by Ludwig Berberich in Vienna in 1934 without string instruments (the violins being replaced by the alto voice during bars 1-14). The new edition (Nowak-Bauernfeind) is in accordance with the original manuscript.[6]
The first section (bars 1–12), a Dorian mode melody sung by the soprano and alto voices in unison, which is accompanied by a counterpoint of the first and second violins, ends on "autem crucis". The second section (bars 13–21), a fugato, modulates to B-flat major and ends on bars 20–21 in forte on "exaltavit illum". The third section (bars 22–31), sustained by the strings and the trombones, ends in a climax in A♭ major on "dedit illi nomen".[2] The fourth section (bars 31 61) begins in pianissimo and in successive entries of the eight voices – from the lowest till the highest vocal parts – establishing a "pyramid" of sound based on an A♭ pedal tone, which leads the a further climax in C major. It is followed on bar 38 by a second "pyramid", which follows the same procedure and ends in D major. The coda on "quod est super" begins on bar 45 with a third "pyramid", which is charged with a greater dramatic effect, and ends on bars 51-53 with an a cappella climax in D minor. The second part of the coda (bars 53–61), sung a cappella, which is a clear quotation of the coda of the Kyrie of the Mass in E minor, ends in pianissimo in D major.[5]
"One has to value this composition as one of the most expressive and monumental works of Bruckner's sacred music…", was a comment by the musicologist Leopold Nowak on his impression of the work.[6]
