Tantum ergo, WAB 32

 ("Let us raise"), WAB 32, is the first of eight settings of the hymn "Tantum ergo" composed by Anton Bruckner in 1845.
History.
Bruckner composed the motet in the fall of 1845 at the end of his stay in Kronstorf or at the beginning of his stay in St. Florian Abbey.
The original manuscript, which was dedicated to the St. Florian Abbey, is stored in the archive of the abbey. A copy made by Bruckner's student Oddo Loidol is stored in the archive of the Kremsmünster Monastery.
The motet was first published without the "facultative" bars as "Pange lingua" by Wöss, Universal Edition, together with the "Vexilla regis" in 1914 – the reason why Grasberger put is as WAB 32 after the Pange lingua, WAB 31. The full version is put in Band XXI/7 of the "".
Music.
The work of 38 bars (36 bars + a 2-bar "Amen") in D major is scored for choir "a cappella". The bars 24 to 34, which Bruckner put as optional, were removed in the first edition.
This early "Tantum ergo", which gives a feeling of angelic purity, is in Schubert's style. The fully conventional first part in D major is followed by a second part, which moves on via the mediant key of F-sharp minor and back to the coda in D major.
