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.”

The Plague

When I speak with Pope Francis, will I ask him to care about sacred music? No. Abuses of the liturgy? No, I will ask him about the root of these problems.

Aurelio Porfiri · August 5, 2014

The Semiologist And The Unbeliever

Once upon a time there was a musician who thought he knew how Gregorian chant should be performed, and was very suspicious of the “semiologists.”

Modernity Impact

For me tradition is not going to the past, but going to the origins.

Aurelio Porfiri · July 30, 2014

Felix Culpa

Life is not a piece of cake. And the Mass is not a Sunday recreational moment. We need to feel the burning of being close to God.

Aurelio Porfiri · July 29, 2014

Missionaries

Maybe today we need missionaries of a different kind, ready to announce the beauty of our faith and tradition with an understanding of the new needs of a changing world.

Facebook, Scammers, and the Economy of Words

No, dear girls, I do not want to know more about you, but maybe it would be good for you to know something more about me.

Basic Steps To Improve Music At Your Parish — Part 7

Guided by this one principle, every parish: “will become a model in its own way, and the liturgical reform, in its essence and demands, will be happily fulfilled.” — Aurelio Porfiri

Fr. Enrico Zoffoli and the Passion of the Lord

“And so, for Jesus – and for us – the Passion is everything, the Passion decides everything.” — Fr. Zoffoli

Confession 2.0

“You know I will never betray you, lol.” How many Hail Marys would this kind of sin deserve?

Aurelio Porfiri · July 15, 2014

I Am Not A Contemporary

Job searching is tough, you say? Try searching as a Church musician who is not “contemporary.”

Aurelio Porfiri · July 10, 2014

Why Did Nobody Inform Me That Latin Was Abolished?

“The request freaked the Deacon out, and, through sweat, he answered that the Council had abolished Latin.”

Aurelio Porfiri · July 8, 2014

Remembering Cardinal Virgilio Noè

If you think that he did not care, as many prelates, about who and what was playing, you would be “hugely wrong.”

Aurelio Porfiri · July 1, 2014

A Name To Remember

If you don’t know who Divo Barsotti is, his discovery will be for you like “exploring a continent for the first time.”

Aurelio Porfiri · June 30, 2014

Appropriate

I am sure 100% of you will agree that: “a rock band is not going to entertain fans at the sound of Gregorian chant.”

Aurelio Porfiri · June 25, 2014

The Downside Of Dialogue

We have a saying in Italy: “The road to hell is paved with good intentions.”

    PDF • “Cantus Mariales” (192 pages)
    Andrea Leal has posted an absolutely pristine scan of CANTUS MARIALES (192 pages) which can be downloaded as a PDF file. To access this treasure, navigate to the frabjous article Andrea posted Monday. The file is being offered completely free of charge. The beginning pages of the book have something not to be missed: viz. a letter from Pope Saint Pius X to Dom Pothier, in which the pope calls Abbat Pothier “a man versed above all others in the science of liturgy, and to whom the cause of Gregorian chant is greatly indebted.”
    —Jeff Ostrowski
    Music List • (2nd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    Like! Like! Like!
    You won’t believe who recently gave us a “like” on the Corpus Christi Watershed FACEBOOK PAGE. Click here (PDF) to see who it was. We were not only sincerely honored, we were utterly flabbergasted. This was truly a resounding endorsement and unmistakable stamp of approval.

Quick Thoughts

    Extreme Unction
    Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.

    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

Many declare that Vatican Council II brought about a true springtime in the Church. Nevertheless, a growing number of Church leaders see this “springtime” as a rejection, a renunciation of her centuries-old heritage, or even as a radical questioning of her past and Tradition. Political Europe is rebuked for abandoning or denying its Christian roots; but the first to have abandoned her Christian roots and past is indisputably the post-conciliar Catholic Church.
