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.”

    PDF • “3-Voice Motet” (Father De Laet)
    I believe 99% of our readers will recognize this hymn tune. Perhaps Father Edgard De Laet should have called it a ‘hymn’ instead of a ‘motet for three voices’—but he’s technically correct, since MOTET is defined as: “a short piece of sacred choral music, typically polyphonic and unaccompanied.” The even verses are for three voices, as you will see if you download the PDF score at #20245. The odd verses may be song a cappella SATB or unison with organ.

    PDF Download • “Hymn for 2 Voices”
    Readers who click on this video will see that it starts with verses of the “Pange Lingua” hymn by Saint Thomas Aquinas (d. 1274) arranged for two voices. However, there’s a polyphonic refrain (“Tantum Ergo”) for three voices, taken from Kevin Allen’s Motecta Trium Vocum. If your choir is very small, this piece is for you! You can download the PDF score free of charge—and you can also utilize the rehearsal videos for each individual voice—by navigating yourself to #20323.

    “Holy Name Hymn” (2-Voice Arrangement)
    When we post a direct URL link, we frequently get thousands of downloads. But when scrolling is required, very few take the time. I mention this because those who click on this URL link and scroll to the bottom can download—completely free of charge—a clever 2-voice arrangement for a famous hymn to the Most Holy Name of Jesus. In a pinch, it can be nicely sung by one male and one female! It will be of interest to those who seek arrangements for two voices.

    “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.

“As a little child, Christ is presented in the temple, the Lawgiver obeying His law. Here the Redeemer offers Himself and is redeemed at a pauper’s price.”
