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.”

President’s Corner

    PDF Download • Introit (2nd Sn. Ord.)
    This coming Sunday, 18 January 2026, is the 3rd 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.

    PDF • “Music List” (Sunday, 11 January)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Feast of the Baptism of the Lord (SUNDAY, 11 January 2025). If such a thing interests you, feel free to download it as a PDF file. The FAUXBOURDON verses for the Communion Antiphon—to say nothing of the antiphon itself—are breathtaking. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the monumental feasts website alongside the official texts in Latin.

Quick Thoughts

    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.

    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.
    —Jeff Ostrowski
    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.
    —Jeff Ostrowski

Random Quote

“Every experienced choirmaster’s work is founded on the following three axioms: (1) Few boys have a really good natural voice; (2) No boy is able to control his voice and produce good tone without training; (3) Most boys have a good ear, and considerable imitative capacity. It is on the last of these axioms that the choirmaster must begin his work.”

— Sir Richard Runciman Terry (1912)
