For fear there won't be enough to confess?I don't encourage practicing any music before Mass
Maybe, or you might just be on a gig: in professional Cathedral choirs it's often the exception to know in advance what will be placed on the music desk. At the parish Church of the Advent of Christ the King in San Francisco, thanks to a very efficient conductor, the half hour rehearsal covered full Gregorian propers, Gradual Psalm, Offertory and Communion motets (for 8vv on the days I was usually called) and a congregational Ordinary setting, plus 4 hymns.If you don't know it just before Mass, yous in trouble.
