Chant help required
It looks like it might finally happen. In an attempt to implement, at least in part, the Benedictine reforms, we have a small schola that is prepared to sing Masses through the year (we thought Candlemas, Annunciation, Visitation, Sacred Heart, Assumption, Triumph of the Cross, All Souls, Immaculate Conception - regular but not too much). The curate wants to celebrate ad orientem and in Latin for all but the readings and the psalm using the Ordinary Form.
We are inexperienced and my fear is that for our first Mass, the offertory and communion for the Assumption will be too much. Would it be better to substitute (as we can according to the GIRM) a simpler Marian antiphon and hymn (e.g. Ave Maria in a simple tone and Ave Maris Stella)?
