Corpus Christi Watershed

Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”

New! • Easy Choral Extension Mass (Ordinary Form)

Guest Author · January 3, 2017

509 Medieval Organist HAVE BEEN recently inspired by the principle of using choral extensions allowing both congregational participation and “a touch of polyphony,” as discussed in a previous post on Corpus Christi Watershed. I think it is a sound principle for those who are trying to find a balanced approach within the Ordinary Form, bring in beautiful elements of the Church’s polyphonic tradition, and increase the moments that we should have a little more reflection within the action of the Liturgy.

Practically speaking, a full polyphonic setting in the context of a regular Ordinary Form liturgy might seem a trifle long, when the action must stop to wait for it. In the heyday of sacred polyphony, and in the context of the Extraordinary Form of the Mass today, the liturgical action may continue during the choral singing of the Ordinary, with the celebrant reciting the texts at the altar sotto voce. This means that, sadly—and not intentionally—great works may be perceived to lose some of their functionality. This is where the principle of choral extensions may come in, where you still want this priceless treasure practically used in the Ordinary Form Mass.

So, I have devised this Mass setting, which I’ve given the name Missa Misericordiae Dei (Mass of the Mercy of God), which incorporates the most common ICEL Roman Chants of the Kyrie, Sanctus, Memorial Acclamation, Great Amen, and Agnus Dei, with excerpts from the Missa Octavi Toni by Orlando de Lassus (for SATB). This allows for the congregation to join in with the “Chant” section of each of the parts and the choir to provide some polyphony either between or at the end of the section. I have provided the ICEL chants with a possible SATB choral harmonisation, to allow for them to be sung without organ accompaniment, as would seem to be more fitting in the penitential seasons of the year, particularly Advent and Lent. It would be, however, perfectly reasonable to ignore these harmonisations and sing the melodies in unison and break into the polyphony where it begins. The ICEL Chants are given in their English form. They could equally be sung in Latin, or any other language should that be desired or required.

    “Lamb of God” (Musical Setting)
    The MASS OF SAINT ANNE LINE has been quite popular ever since ROMAN MISSAL Third Edition was released circa 2011. You can now download the musical score (PDF) for this setting, placed into five (5) different keys; i.e. “pitch levels” that are high and low. This makes it possible to adjust based upon who’s singing at which time of day.

    PDF Download • Introit (2nd Sn. Ord.)
    This coming Sunday, 18 January 2026, is the 2nd Sunday in Ordinary Time (Year A). The ENTRANCE CHANT is set according to the fourth mode, which sounds ‘serious’ or ‘dark’ or ‘haunting’ or ‘mysterious’—and its English adaptation corresponds to the authentic version (“Omnis terra adóret”) found in the GRADUALE ROMANUM. In this rehearsal video (click here) I attempt to sing the melody while simultaneously accompanying myself on the organ. I encourage you to print off the organ accompaniment (PDF) and play through it, because the harmonies are delightful.

    Spectacular Communion Setting!
    The FAUXBOURDON setting of the Communion for the Baptism of the Lord (which will occur this coming Sunday) strikes me as quite spectacular. The verses—composed by the fifth century Christian poet, Coelius Sedulius—come from a long alphabetical acrostic and are deservedly famous. The feast of the LORD’S BAPTISM was traditionally the octave day of Epiphany, but in the 1962 kalendar it was made ‘more explicit’ or emphasized. The 1970 MISSALE ROMANUM elevated this feast even further.

    “Reminder” — Month of January (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.

Random Quote

“The Second Vatican Council has not been treated as a part of the entire living Tradition of the Church, but as an end of Tradition, a new start from zero. The truth is that this particular council defined no dogma at all, and deliberately chose to remain on a modest level, as a merely pastoral council; and yet many treat it as though it had made itself into a sort of superdogma which takes away the importance of all the rest.”

— Cardinal Ratzinger (speaking formally as head of the CDF)
