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.”

Jeff Ostrowski · October 8, 2024

EXT TIME A PRIEST insists that it’s wrong for the choir alone to sing pieces at Mass (because “true” participation means the congregation must sing everything) don’t tell him his statement is in direct violation of SACROSANCTUM CONCILIUM §114. Instead, try taking a different approach. In a respectful and calm manner, say to that priest: “Okay, then the entire congregation must read the Gospel along with you at Mass—because if they just listen while you read the Gospel, they’re not truly participating according to your logic.”

Choral Extensions • It’s incorrect to say the congregation must sing everything at Mass. On the other hand, since the 1950s there’s been a real push for congregational singing. Failing to recognize this is foolish. Indeed, a music director who completely ignores congregational singing runs the risk of being fired by the pastor! In my seminar, Secrets of the Conscientious Choirmaster, I harp on something I call choral extensions. Basically, choral extensions allow a choirmaster to introduce polyphony without getting fired. When it comes to the congregational SANCTUS we use at my parish (which can be sung in Latin, English, or Spanish), the following “extends” it polyphonically:

Freedom To Shape • With regard to SANCTUS XVI, perhaps you’ve noticed how each church sings it in a slightly different manner. That’s because the official edition gives freedom to choirmasters to “shape” each phrase according to its text. For example, here’s how it appeared in a famous edition by Dr. Franz Xaver Mathias (an Alsatian priest). Father Mathias was organist at STRASBURG CATHEDRAL, where he founded the Saint Leo Institute for Church Music in 1913:

Renewal of Challenge • In many recent articles, I’ve been recommending the Brébeuf Catholic Hymnal. I believe this book is indispensable for any serious Catholic choirmaster. (I certainly couldn’t run my choral program without it.) I don’t use the “P-word” word lightly, but I’m comfortable calling the BRÉBEUF HYMNAL peerless. Indeed, one of the main authors for the Church Music Association of America weblog declared (6/10/2022) that the BRÉBEUF HYMNAL “has no parallel and not even any close competitor.” For years, I’ve been searching for a qualified partner willing to debate this assertion over zoom. Today—8 October 2024—I respectfully renew my challenge. Our website garners millions of hits, but so far nobody has accepted my challenge.

    PDF Download • “Atténde Dómine”
    Although it isn’t nearly as ancient as other hymns in the plainsong repertoire, Atténde Dómine, et miserére, quía peccávimus tíbi (“Look down, O Lord, and have mercy, for we have sinned against Thee”) has become one of the most popular hymns for LENT—perhaps because it was included in the famous Liber Usualis of Solesmes. This musical score (PDF file) has an incredibly accurate version in English, as well as a nice version in Spanish, and also the original Latin. Although I don’t claim to have a great singing voice, this morning I recorded this rehearsal video.

    Music List • (1st Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I’ve prepared for this coming Sunday—22 February 2026—the 1st Sunday of Lent (Year A). 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 available at the outstanding feasts website alongside the official texts in Latin. I spent an enormous amount of time preparing this ORDER OF MUSIC—because the children’s choir will join us—and some of its components came out great. For example, the COMMUNION ANTIPHON with Fauxbourdon is utterly resplendent, yet still ‘Lenten’.

    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

10 February 1588: “All incompetent singers in the cathedral are warned that they must immediately begin to improve themselves or be fined. Regularly scheduled practice hours shall be announced, and all incompetents must attend. No one shall henceforth sing anything by way of a solo except those whose names the dean communicates to Guerrero.”

— From the “Life of Father Francisco Guerrero”
