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.”

I’m currently in the process of creating a website where all the organ accompaniment booklets for Vespers are posted for download. At the moment, you can download the 25-page booklet I used yesterday, to accompany vespers for Sexagesima Sunday.

Hymn by Cardinal Newman

During the season of Septuagesima, we will be using this hymn by Cardinal Newman, which employs both Latin and English. (Readers probably know that Cardinal Newman was one of the world’s experts when it comes to Lingua Latina.) The final verse contains a beautiful soprano descant. You can hear this brief excerpt taken during our […]

Church Music Shouldn’t Be “Headache-Inducing”

Introit • Candlemas (2 February)

“Candlemas” • Our choir sang on February 2nd, and here’s a live recording of the beautiful INTROIT: Suscépimus Deus. We had very little time to rehearse, but I think it has some very nice moments. I promise that by the 8th Sunday after Pentecost it will be perfect! (That Introit is repeated on the 8th […]

Simplified Antiphons • “Candlemas”

Anyone who desires simplified antiphons (“psalm tone versions”) for 2 February, the Feast of the Purification—which is also known as “Candlemas” or the Feast of the Presentation—may freely download them. The texts of the antiphons are quite beautiful. From “Lumen Ad Revelatiónem Géntium” you can hear a live excerpt (Mp3). I’m not a fan of […]

Once, after Mass, my pastor said he really loved the hymn we did. I said: “Father, that’s Holy God, We Praise Thy Name—you never heard it before?” He replied: “But the way you did it was terrific. For once, it didn’t sound like a funeral dirge!” Last Sunday, our volunteer choir sang that hymn. I […]

Don’t You Agree About These?

If you want to make Jeff Ostrowski really happy, send him an email with effusive praise about the individual voice recordings for hymn #296. [Soprano, Alto, Tenor, Bass] They came out dazzlingly sensational, don’t you agree?

Choral Vowels? Yes? No?

Here’s a live recording of one of the choral “warm-up” exercises my choir enjoys. It was taken during our rehearsal on 27 January 2023. It’s good to make sure each chord is perfectly in tune and balanced before moving to the next one. That only happens when each singer has the correct vowel. If you […]

    “Simplified” Keyboard Accompaniment (PDF)
    I’d much rather hear an organist play a simplified version correctly than listen to wrong notes. I invite you to download this simplified organ accompaniment for hymn #729 in the Father Brébeuf Hymnal. The hymn is “O Jesus Christ, Remember.” I’m toying with the idea of creating a whole bunch of these, to help amateur organists. The last one I uploaded was downloaded more than 1,900 times in a matter of hours—so there seems to be interest in such a project. For the record, this famous text by Oratorian priest, Father Edward Caswall (d. 1878) is often married to AURELIA, as it is in the Brébeuf Hymnal.

    ‘Bogey’ of the Half-Educated: Paraphrase
    Father Adrian Porter, using the cracher dans la soupe example, did a praiseworthy job explaining the difference between ‘dynamic’ and ‘formal’ translation. This is something Monsignor Ronald Knox explained time and again—yet even now certain parties feign ignorance. I suppose there will always be people who pretend the only ‘valid’ translation of Mitigásti omnem iram tuam; avertísti ab ira indignatiónis tuæ… would be “You mitigated all ire of you; you have averted from your indignation’s ire.” Those who would defend such a translation suffer from an unfortunate malady. One of my professors called it “cognate on the brain.”
    —Jeff Ostrowski
    Father Cuthbert Lattey • “The Hebrew MSS”
    Father Cuthbert Lattey (d. 1954) wrote: “In a large number of cases the ancient Christian versions and some other ancient sources seem to have been based upon a better Hebrew text than that adopted by the rabbis for official use and alone suffered to survive. Sometimes, too, the cognate languages suggest a suitable meaning for which there is little or no support in the comparatively small amount of ancient Hebrew that has survived. The evidence of the metre is also at times so clear as of itself to furnish a strong argument; often it is confirmed by some other considerations. […] The Jewish copyists and their directors, however, seem to have lost the tradition of the metre at an early date, and the meticulous care of the rabbis in preserving their own official and traditional text (the ‘massoretic’ text) came too late, when the mischief had already been done.” • Msgr. Knox adds: “It seems the safest principle to follow the Latin—after all, St. Jerome will sometimes have had a better text than the Massoretes—except on the rare occasions when there is no sense to be extracted from the Vulgate at all.”

Quick Thoughts

    “Reminder” — Month of November (2025)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    Gospel Options for 2 November (“All Souls”)
    We’ve been told some bishops are suppressing the TLM because of “unity.” But is unity truly found in the MISSALE RECENS? For instance, on All Souls (2 November), any of these Gospel readings may be chosen, for any reason (or for no reason at all). The same is true of the Propria Missæ and other readings—there are countless options in the ORDINARY FORM. In other words, no matter which OF parish you attend on 2 November, you’ll almost certainly hear different propers and readings, to say nothing of different ‘styles’ of music. Where is the “unity” in all this? Indeed, the Second Vatican Council solemnly declared: “Even in the liturgy, the Church has no wish to impose a rigid uniformity in matters which do not implicate the faith or the good of the whole community.”

    “Our Father” • Musical Setting?
    Looking through a Roman Catholic Hymnal published in 1859 by Father Guido Maria Dreves (d. 1909), I stumbled upon this very beautiful tune (PDF file). I feel it would be absolutely perfect to set the “Our Father” in German to music. Thoughts?

Random Quote

“A flawless harmonization of Gregorian chant cannot be created by improvisation, no matter the competence and ability of the organist or harmonist.”
