Simple English Proper (Lumen Christi Gradual and Modal Responsorial Psalms). The Roman Missal gives us these Bible verses to be sung per the examples recorded: the congregation joins the cantor for the antiphon (printed), then the cantor sing the Psalm alone, then the congregation and cantor repeat the antiphon.
Singing the proper of the mass promotes music literacy. The Church invented music literacy for her liturgy, yet nowadays most Church musicians must hear the music of the mass before they can sing it. An illustration of how the Church uses solfege to teach music literacy is provided with the “Solfeggio” videos of this Sunday’s Introit (scroll down).
