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.”

    “Sanctus VIII” • Organ Accompaniment
    A few days ago, I composed this organ harmonization for SANCTUS VIII. This Mass is traditionally called Missa de ángelis or “Mass of the angels.” In French, it is Messe de Anges. You can evaluate my attempt to simultaneously accompany myself on the pipe organ (click here) while singing the melody. My parish is currently singing this setting.

    Music List • (5th Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday, 8 February 2026, which is the 5th Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. You will probably notice it isn’t as ‘complete’ or ‘spiffy’ as usual, owing to some difficulties which took place this week.
    —Jeff Ostrowski
    PDF • “Communion” (5th Sunday in Ordin.)
    The COMMUNION ANTIPHON for this coming Sunday, 8 February 2026—which is the 5th Sunday in Ordinary Time (Year A)—is truly delightful. You can download the musical score completely free of charge. This text will be familiar to altar boys, because it’s PSALM 42. The Feder Missal makes the following claim about that psalm: “A hymn of a temple musician from Jerusalem: he is an exile in a heathen land, and he longs for the holy city and his ministry in the Temple there. The Church makes his words her own.”

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”
    —Jeff Ostrowski
    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.

Random Quote

And since it is becoming that holy things be administered in a holy manner, and of all things this sacrifice is the most holy, the Catholic Church, to the end that it might be worthily and reverently offered and received, instituted many centuries ago the holy canon, which is so free from error that it contains nothing that does not in the highest degree savor of a certain holiness and piety and raise up to God the minds of those who offer.

— Council of Trent (1562)
