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.”

Views from the Choir Loft

Ben Shapiro Teaches His Audience Music Theory!

Jeff Ostrowski · February 4, 2021

E HAVE SPOKEN in the past about our policy regarding USA politics. Most recently, this subject was broached in an article (“A Glaring Omission in the Post-Vatican II Lectionary”) which has proven to be one of our most popular. I hope someone who has power in the Church will read about Father Valentine’s discovery and take action. Regarding USA politics, I have posted “Only In Secret And With Horror”—a PDF document explaining my personal views—in case anyone is curious.

A certain member of my family is a huge Ben Shapiro fan. (Mr. Shapiro is a YouTube political commentator; he’s not related to O.J. Simpson’s lawyer, Robert Shapiro.) Because I have a professional degree in music theory, my opinion was sought:

N.B. I have no feelings for or against Ben Shapiro’s political views. I commend him for speaking to his audience about music theory. Many of our political problems could be solved if more pundits did likewise!

Fact Check: Mr. Shapiro is correct that a seventh—especially a major seventh—is extremely dissonant. However, he’s incorrect to say the 7th was called diabolus in musica (“the devil in music”). That interval was a Tritone, not a 7th. Both intervals are extremely dissonant. In classical polyphony, the Tritone should normally be avoided—yet it can be quite beautiful. For instance, consider the opening movement to Missa Ave Maris Stella by Father Victoria (d. 1611):

That Tritone is actually quite beautiful—and we will speak of it below.

Can Amateurs Sing Polyphony?

I recently had occasion to recruit members for two choirs. I deliberately mixed “novice” members with “veteran” members. When I say “novice,” I mean young men and young women who have never sung in a choir before. They didn’t realize they could match pitch until I interviewed them. (I heard more than fifty auditions, and it took forever!) We only had one rehearsal before our first Mass, and that’s pretty daunting. But we made it just fine, thanks to the singers who have worked with me in the past and, therefore, knew some of the repertoire. I recorded our very first Sunday, and I can already tell: These two choirs are going to be superb!

Our Treble Choir (females only) sang hymns from the Brébeuf hymnal. Since it was Septuagesima Sunday, they sang the appointed hymn for the season of Septuagesima until Lent: Rebus Creatis Nil Egens (which is #403 in the Brébeuf Hymnal). The Brébeuf Hymnal is the only book which provides a literal English translation of this hymn, which helps the singers to pray.

They added the Alto line, with great effect:

*  Mp3 Download • Brébeuf Hymn #403
—The Saint Jean de Brébeuf Hymnal Choral Supplement.

The Treble Choir also added harmonies to a lovely Marian hymn, #761 in the Brébeuf Hymnal:

*  Mp3 Download • Brébeuf Hymn #761
—The Saint Jean de Brébeuf Hymnal Choral Supplement.

The Treble Choir did a Canon by William Byrd (d. 1623), and I attempted to add the bottom line—but my voice isn’t what it used to be:

*  Mp3 Download • “Non Nobis” Canon
—Rehearsal videos are #88208.

Inspired by Dr Lucas Tappan’s article, I attempted some organ improvisation. Can you tell which melody I chose?

*  Mp3 Download • Organ Improvisation

The Mixed Choir also did an amazing job. Of course there was unison singing, but I never place women an octave above the men when it comes to plainsong. (I would be curious to know how the other contributors to Views from the Choir Loft feel about men and women singing plainsong separated by an octave.) Personally, my ear cannot stand that sound. On the other hand, that is how the choir at Westminster Cathedral sang Gregorian chant and a YouTube recording from the 1930s demonstrates this. In any event, here’s how we sing Gregorian chant—alternating between men and women:

*  Mp3 Download • Credo IV (excerpt)
—The men alternate with the women.

We attempted a setting of O Sanctissima by Maria Quinn. This setting alternates between 2-voice with organ and SATB harmony. The harmonies are very modern, as shown by marker 0:15 here:

*  Mp3 Download • “Modern” Chord at 0:15

The mixed choir didn’t tune perfectly, but they made a gallant effort (cf. marker 0:36). I guarantee this piece will be perfect after we sing it a few more times:

*  Mp3 Download • Maria Quinn “O Sanctissima”

Getting Back To “Missa Ave Maris Stella”

The mixed choir also sang the Kyrie from Father Victoria’s Missa Ave Maris Stella. It wasn’t perfect—remember that several of these singers had never sung polyphony before—but I was thrilled with the result considering we’d only had one rehearsal:

*  Mp3 Download • Victoria Kyrie (Rec. Live)
—Download this score at #89425.

The entire Mass is a phenomenal masterpiece. As we know, the Gregorian Chant “Ave Maris Stella” has a characteristic of an ascending perfect fifth, which then becomes a descending fifth at the words “Dei Mater.” From a theoretical point of view, a perfect fifth inverts to a perfect fourth—and Father Victoria employs both in the first section and the second section (as did Giovanni Animuccia, in his Missa Ave Maris Stella). When we realize that fourth can substitute for a fourth, Father Victoria’s plan becomes clear. He uses the plainsong melody:

I have attempted to indicate for you the contour:

Throughout the first movement and the third movement, Father Victoria constantly imitates this contour:

Here is Dr. Horst Buchholz conducting that exact section during the Sacred Music Symposium a few years ago.

In the second movement, Father Victoria “hits you over the head” with the ancient Cantus Gregorianus melody:

It would take forever to indicate everything clever done by Father Victoria. Therefore, just look at the part book—courtesy of Nancho Alvarez—where I have used colors: Red is “Ave Maris Stella”; Green is “Felix Caeli Porta”; Blue is “Dei Mater Alma”; Yellow is “Atque Semper Virgo.”

The chant appears in the Editio Vaticana as follows: Ave Maris Stella (PDF)

Here are some Ave Maris Stella organ accompaniments.

Secrets Revealed

Finally, the secret to training volunteer choirs is to pick the perfect repertoire for them. It must be powerful and dignified, but not too difficult.

    Dom Pothier • Photo from 1904
    Dom Paul Cagin, in a 1904 publication (L’oeuvre de Solesmes dans la restauration du chant grégorien) made sure to include a beautiful image of Dom Pothier, the legendary abbot of St-Wandrille. Also shown is a very young Dom André Mocquereau. Auguste Pécoul—considered the spiritual “son” of Abbat Prosper Guéranger of Solesmes—wrote as follows on 24 June 1901: “To forestall any confusion, let us remember that there is just one Gregorian notation—that restored, according to the ancient manuscripts, by the eminent Abbot of Saint-Wandrille, Dom Pothier.” ✠

    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.
    —Jeff Ostrowski
    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.

Quick Thoughts

    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.”

    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

“The Humanists abominated the rhythmical poetry of the Middle Ages from an exaggerated enthusiasm for ancient classical forms and meters. Hymnody then received its death blow as, on the revision of the Breviary under Pope Urban VIII, the medieval rhythmical hymns were forced into more classical forms by means of so-called corrections.”

— ‘Father Clemens Blume, S.J.’
