I will be playing for a funeral tomorrow which will be combined with the parish's regular weekday Mass. I know the rubrics regarding instrumental music at Requiem Masses, but the pastor still wants preludes at funeral Masses. I am thinking of playing the Webber Pie Jesu as an instrumental prelude. Do you think this would be a good choice? I think it might sound a little odd to the regular weekday Mass attendees that know the piece, since they don't know that there's a funeral until the Mass begins. Even in spite of this, do you think it would still be okay since the entire month of November is dedicated to the faithful departed?
