History.
Bruckner composed this motet on 9 June 1846 during his stay in St. Florian Abbey. The autograph voice score, without the organ score, is present in the archive of the St. Florian Abbey.
In 1888, Bruckner revised this setting, together with the revision of previous four "Tantum ergo". The revised version of the five "Tantum ergo" was published first by Johann Groß, Innsbruck in 1893.
The 1846 and 1888 versions are put in Band XXI/13 and 38 of the "" respectively.
Music.
The works is scored in D major for choir and organ. The first setting is 36-bar long. The bars 21-32 are optional. In the 31-bar long revised version 8 bars are removed and a 3-bar "Amen" is added.
This fifth "Tantum ergo" is characterised by its marked solemness. After a climax on "novo cedat rituit" it goes on, diminuendo, to an intimate quasi-Mozartian coda.
