Tantum ergo, WAB 43

Tantum ergo ("Let us raise"), WAB 43, is the second of eight settings of the hymn Tantum ergo composed by Anton Bruckner in c. 1845.

History
Bruckner composed the motet in the fall of 1845 at the end of his stay in Kronstorf or in 1846 at the beginning of his stay in St. Florian Abbey. The original manuscript, on which the Chorale Dir, Herr, dir will ich mich ergeben is also found, is stored in the archive of the abbey. Two copies of the manuscript are also stored in the Österreichische Nationalbibliothek.

The motet was first published in band II/2, pp. 116–118 of the Göllerich/Auer biography. The full version is put in Band XXI/8 of the Gesamtausgabe.

Music
The work of 36 bars in A major is scored for SATB choir and organ.

Joseph Anton Pfeiffer, the organist of Seitenstetten Abbey, to whom Bruckner gave the composition for critical analysis, found Bruckner "ein ächtes musikalisches Genie" ("a real musical genius").
