Two Asperges me, WAB 3

The two (Thou wilt sprinkle me), WAB 3, are sacred motets composed by Anton Bruckner. They are settings of the Latin Asperges me, the antiphon used for the celebration of Asperges.
History.
In 1844/1845, Bruckner composed these two settings of "Aperges me" during his stay in Kronstorf. They were presumably performed at that time.
The manuscripts are stored in the "Österreichische Nationalbibliothek". The two motets were first published in band II/2, pp. 67–76 of the Göllerich/Auer biography. They are put in Band XXI/6 of the "".
Music.
During his stay in Kronstorf Bruckner, composed these two settings of the "Asperges me" for mixed choir and organ (1844/1845). As for the former "Asperges me", the incipit ("Asperges me") is not composed and has to be intoned by the priest in Gregorian mode before the choir is going on. It is the first composition, at the end of which Bruckner has put his signature.
