The Asperges Me, Domine can be sung on any Sunday. In the NO it replaces the Penetential Rite. Start the Mass with the Introit as usual (the Priest enters already vested in Cope, he incenses the Altar whilst the Introit is being sung, then he begins the ritual of blessing and salting the water, he then starts the AMDomine. The Gloria follows. I propose that during Advent and Lent the simple setting of AMDomine is used. Regarding use of the organ herewith: whilst it is often said that plainchant does not require the organ, that was ok pre-Vatican 2, and even in those times the congregation did have some parts to sings. With increased importance now placed upon congregation being able to assist in the singing and, the usual shortage of singers these days, the organ does encourage them, so, I suggest using the organ - including during Advent and Lent.

I have created an adaptation of the 2011 Missal text, and due to my recent interest in the mensural interpretation of chant, chanted it in accordance with said principles.
