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.”

Singers • High or Low?

I consider myself a “flexible” choirmaster. When I sing with men who have low voices, I join with them at a low pitch. Here’s an excerpt from yesterday, which was LAETARE SUNDAY (the 4th Sunday of Lent). Later that same day, I sang at another Mass with a singer who has a very high voice. […]

I agree with Keven Smith that Covid-19 has been a huge boon to my skills of improvisation on the organ. I wanted to share this amazing email (which gave me such joy), sent to me by somebody I don’t know: “My name is —— and I attended the 7:00pm Mass today at St Vitus. The […]

11 March 2021 • From Last Sunday…

Like everyone else, we are struggling under the Covid-19 restrictions. The number of singers we’re allowed have has been reduced in a severe way. But we charge forward, trusting in God. Here is a 50-second live excerpt from Mass last Sunday here in Los Angeles. Not many voices, but still beautiful (in my humble opinion).

4 March 2021 • Can you spare 15 seconds?

Due to Covid-19, California has basically been under “lock down” for 11 months, and these restrictions have had quite a detrimental effect on choral programs. We are frequently limited to just 2-3 singers, on account of regulations by the government and our Archdiocese. However, although the number of singers is quite small, I was struck […]

3 March 2021 • “A policeman” — really?

According to Monsignor Frederick R. McManus, there were “policemen” serving the Sanhedrin in the time of Our Blessed Lord. Look at this awful translation in the 1966 “Saint Andrew Bible Missal” from 1966. Yuck!

    “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.
    —Jeff Ostrowski

Random Quote

“In my opinion, there should be reached the aim that all priests could continue to use the old Missal.”
