Asperges me, WAB 4

 (Thou wilt sprinkle me), WAB 4, is a sacred motet composed by Anton Bruckner. It is a setting of the Latin Asperges me, the antiphon used for the celebration of Asperges.
History.
In 1843–44, Bruckner composed this first setting of "Asperges me" during his stay in Kronstorf. It is not known when it was performed at that time.
The work, the original manuscript of which is lost, exists as a transcription by Arthur Bauer. The motet was first published in volume III/2, pp. 140–141 of the Göllerich/Auer biography. It is put in volume XXI/4 of the "".
Music.
The work is a setting of 32 bars in F major of the "Asperges me" for mixed choir "a cappella".
According to the Catholic practice, the incipit (""Asperges me") is not composed and has to be intoned by the priest in Gregorian mode before the choir begins. The score is in two sections. Section 1 (7 bars) begins with "Domine, hysopo" and ends with "dealbabor". Section 2 (18 bars) begins with the remaining of the text, and is followed by the doxology ("Gloria Patri""). Thereafter the incipit is repeated by the choir in unison, concluded by a "da capo" of section 1. The second section contains audacious modulations, similar to the contemporaneous "Kronstorfer Messe".
