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.”

Square Note App

Fr. David Friel · April 9, 2017

ELL PHONES and other mobile devices these days serve manifold purposes. For some, they double and triple as cameras and internet browsers. For others, they also function as gaming devices, tip calculators, searchable Rolodexes, stereo systems, navigation systems, and portable televisions. But, have you ever used your mobile device as a Graduale Romanum?

Now you can, if you would like.

Recently, I stumbled upon an app called Square Note, which markets itself to church musicians and those who wish to learn more about chant. The app allows users to see a wide array of chants, with their texts and square notation. The chants are grouped in four major sections.

First, the Mass propers for the Ordinary Form encompass the whole temporal cycle and part of the sanctoral. Secondly, Mass propers are also available for the temporal cycle of the Extraordinary Form. Also included is a Kyriale section complete with all eighteen chant Masses and six chant creeds. Finally, the app offers a collection of “Other Chants,” which includes multiple versions of the Marian antiphons, certain Eucharistic chants, and several tones for the Te Deum.

One of the most useful features of the app is its capability of searching the texts of all the chants. Searches can be limited to the titles, or incipits, of the chants, or searches may be opened to include the full text of all the chants. For students of the liturgy, this tool is especially valuable.

Another feature that can be useful is the playback mode offered for each piece. Although this would unsettle purists, I can imagine the playback being useful for beginners. The tone quality of the playback is, of course, choppy and mechanistic, so its overuse ought to be avoided. I’ve known many schola directors who will not use a piano to find pitches or sound out passages, and there is real wisdom in their approach. For some, though, the playback mode offered in Square Note could be the help they need to get off the ground. Square Note even allows the user to adjust the pitch and tempo of the playback tool.

This app is the handiwork of Fr. Matthew Spencer, O.S.J. and Bro. Stephen Spencer, O.S.J., both members of the Holy Spouses Province of the Oblates of St. Joseph in the United States of America. It is a developing product, too, as more chants continue to be added to the collections.

The app is available for $2.99 in the Apple App Store or on Google Play. Click here to explore more fully the riches of this “Rituale in your pocket.”

President’s Corner

    “Offertory” at Catholic Funerals
    I have argued that the OFFERTORY—at least in its ancient form—is more of a responsory than an antiphon. The 1962 Missal specifically calls it “Antiphona ad Offertorium.” From now on, I plan to use this beautiful setting (PDF) at funerals, since it cleverly inserts themes from the absolution of the body. Tons more research needs to be done on the OFFERTORY, which often is a ‘patchwork’ stitching together various beginnings and endings of biblical verses. For instance, if you examine the ancient verses for Dómine, vivífica me (30th Sunday in Ordinary Time) you’ll discover this being done in a most perplexing way. Rebecca Maloy published a very expensive book on the OFFERTORY, but it was a disappointment. Indeed, I can’t think of a single valuable insight contained in her book. What a missed opportunity!

    “In Paradisum” • Gregorian Chant
    As a RECESSIONAL on All Souls’ Day (November 2nd), we will sing In Paradísum Dedúcant Te Ángeli (PDF). When it comes to Gregorian Chant, this is one of the most popular “songs.” Frankly, all the prayers and chants from the traditional REQUIEM MASS (Missa exsequialis or Missa pro defunctis) are incredibly powerful and never should’ve been scuttled. Click here to hear “In Paradisum” in a recording I made this afternoon. Professor Louis Bouyer spoke of the way Bugnini “scuttled the office of the dead” in this fascinating excerpt from his memoirs. In his book, La riforma litugica (1983), Bugnini bragged—in quite a shameful way—about eliminating the ancient funeral texts, and even admitted those venerable texts were “beloved” (his word) by Catholics.

    “Music List” • All Souls (2 November)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 2 November 2025, which is the Commemoration of All the Faithful Departed (“All Souls”). 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 top-notch feasts website alongside the official texts in Latin. In my humble opinion, it’s weird to have the feast of All Saints on a Sunday. No wonder the close associate of Pope Saint Paul VI said the revised KALENDAR was “the handiwork of a trio of maniacs.” However, I can’t deny that sometimes the sacred liturgy consists of elements that are seemingly contradictory: e.g. the Mode 7 “De Profúndis” ALLELUIA, or the Mode 8 “Dulce lignum” ALLELUIA on the various ancient feasts of the Holy Cross (3 May, 14 September, and so on).

Quick Thoughts

    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?

    New Bulletin Article • “12 October 2025”
    My pastor requested that I write short articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The latest article (dated 12 October 2025) talks about an ‘irony’ or ‘paradox’ regarding the 1960s switch to a wider use (amplior locus) of vernacular in the liturgy.

Random Quote

“The Catholic Church holds it better for the sun and moon to drop from heaven, for the earth to fail, and for all the many millions on it to die of starvation in extremest agony, as far as temporal affliction goes, than that one soul, I will not say, should be lost, but should commit one single venial sin, should tell one willful untruth, or should steal one poor farthing without excuse.”

— Saint John Henry Newman (1865)
