Thou wilt sprinkle me in F major, WAB 4

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.
