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.”

21 July 2020 • From a Musicology PhD…

To you and your colleagues who helped produce the Brébeuf hymnal, I wanted to drop a line to say “bravo.” I just got a copy and immediately ordered the choral supplement (I ought to have just gotten it in the first place). What an achievement this book is! This is the sort of hymnal one […]

Wonderful emails received recently…

(#1) “Thank you for all the great work you do to provide music and rehearsal videos for all of us to use! It has been invaluable to those music and choir directors who’ve had to build a Gregorian chant schola from scratch! May God continue to bless all you do to promote sacred music for […]

Honesty and Integrity

Someone who made a generous donation wrote as follows: While I sometimes strongly disagree with the content or tone of the blog article authors, I, as a parish music director, have used CCWatershed’s resources countless times and have always found the site to be an excellent source of high-quality Sacred Music, which is very hard […]

Sonata during the Gradual?

Wolfgang Amadeus Mozart wrote seventeen Church Sonatas between 1772 and 1780. These are short pieces intended to be played between the Epistle and the Gospel (during Mass). Shortly after Mozart left Salzburg, the Archbishop mandated that an appropriate choral motet or congregational hymn be sung at that point in the liturgy, with the result that […]

Note from a reader (25 June 2020)

“Just visited your website for the first time 5 minutes ago. Was that struck by the beauty of the chant and the immense gift of such a beautiful collection that can be downloaded with ease…at no charge! In awe of the gift of this extensive content and the amount of labor that has gone into […]

Positive Message from a Catholic Priest

Today, we received this wonderful message from a Catholic Priest: I want to say thank you for everything you have done to bring back the sense of the sacred in The liturgy. We are going through a liturgical renewal here in the parish where I was assigned as a parochial vicar. I’ve only been a […]

Pentecost Melody Added

Let it be known: I have added the Pentecost melody (“Veni Creator Spiritus”) to the Seasonal Benediction website. I am slowly adding all the different melodies for the “O Salutaris Hostia”—so we can be seasonally appropriate during Benediction of the Blessed Sacrament.

From a Catholic priest…

Regarding the CCW mailing list, a priest (Father E. J.) wrote to us yesterday: “Sometime ago, you wrote something along the lines that none of your emails are copies or merely pitches; each one is individual. I respect you so much for that. I don’t always get to read through them, but they remain in […]

Does Gregorian Chant ever skip a 7th?

I’ve really been enjoying singing from the Père Daniel Kyriale (126 pages), which is a fabulous little book. I had no idea it would turn out so nicely—incredibly useful, and the printing is super crisp. I noticed something quite strange the other day: Kyrie X (an extremely ancient chant) contains a skip of a seventh. […]

We love getting messages like this one…

“I am a 25-year-old organist and cantor from the mountains of Northern Colorado. I wanted to take this opportunity to thank you and your friends for working hard to bring excellent content to your website and my inbox. I have found many, many awesome resources to help me stay faithful to the Church’s stance and […]

What is the “Ordinary” of the Mass?

A few years ago—during the Sacred Music Symposium—I suggested to the audience that the “Our Father” and the “Alleluia” should be considered part of the Ordinary of the Mass (for the Ordinary Form). In my own settings, such as Mass of the English Martyrs, I treated the “Our Father” accordingly—and here in Los Angeles, we […]

Being Too Hard On Priests?

I’m usually a stickler when it comes to making sure priests sing their chants correctly, especially when priests often substitute a Perfect Fourth for the Minor Third in the famous Triple Alleluia on Holy Saturday. But I just found out the 1575AD Missale Romanum has a skip of a Perfect Fifth! So perhaps I need to […]

Dealing With Calumny

All of us have probably been the victim of calumny. Calumny can be especially painful if the person telling lies is someone you helped. Next time this happens in your life, try an experiment: Write the person’s name on an Index card, place it on your shoulder, and flick it to the ground—meaning you will […]

From “Vexilla Christus Inclyta”

Non ille regna cládibus, | Non vi metúque súbdidit: | Alto levátus stípite, | Amóre traxit ómnia.—“It is not by combat or force or fear that Christ subdues nations but lifted up upon the tree, he draws all things to himself by love.” Servat fides connúbia, | Juvénta pubet íntegra, | Pudíca florent límina | […]

“Daily I sat in the temple, close to you…”

Fulton J. Sheen always said the “very best translation” of Sacred Scripture was the version by Monsignor Ronald Knox, and here’s what Knox had for the Passion read today (Pre-1955 Palm Sunday): “And Jesus said to the multitude at that hour, You have come out to my arrest with swords and clubs, as if I […]

President’s Corner

    “Music List” • 17th in Ordinary Time (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I prepared for the 17th Sunday in Ordinary Time (27 July 2025). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the the feasts website.
    —Jeff Ostrowski
    Communion • “Ask & You Shall Receive”
    All of the chants for 27 July 2025 have been added to the feasts website, as usual under a convenient “drop down” menu. The COMMUNION ANTIPHON (both text and melody) are exceedingly beautiful and ancient.
    —Jeff Ostrowski
    Jeff’s Mother Joins Our Fundraiser
    To assist our fundraiser, Mrs. Kathleen Ostrowski has drawn several beautiful sketches which she offers to all our readers free of charge. If you have a moment, I invite you download them at this link.

Quick Thoughts

    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.
    —Corpus Christi Watershed
    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.
    —Corpus Christi Watershed
    Antiphons Don’t Match?
    A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).

Random Quote

“Like all other liturgical functions, like offices and ranks in the Church, indeed like everything else in the world, the religious service that we call the Mass existed long before it had a special technical name.”

— ‘Rev. Adrian Fortescue (THE MASS, page 397)’
