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

    “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.
    —Jeff Ostrowski
    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.
    —Jeff Ostrowski
    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.

Quick Thoughts

    “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.
    —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

“To me nothing is so consoling, so piercing, so thrilling, so overcoming, as the Mass, said as it is among us. I could attend Masses for ever, and not be tired.”

— John Henry Cardinal Newman (1848)
