Video • Most Pure Heart of Mary Schola Cantorum

Dr. Lucas Tappan · May 17, 2016

UR PARISH in 2011 founded the Most Pure Heart of Mary Schola Cantorum to answer the Church’s call to establish schools of music to train young people the art of sacred music. Each year we have seen the program expand, and we look forward to working with more than 60 students next year from six local Catholic schools and home school programs.

Even though the Schola Cantorum is primarily attached to our parish, its work reaches far beyond. Several years ago one of our high school boys became one of our archdiocesan seminarians. While I don’t take credit for his vocation, he once told me that singing in the choir gave him a much better understanding of the Mass.

This year, one of our high school girls is graduating and moving on to study organ at the university. Her plan is to finish her Master Degree and then apply for the Organ Scholar position at Westminster Cathedral in London. If anyone has the drive to make that happen, she is the one.

One of our 8th grade students, who plans to sing in the Schola Cantorum through high school, has fallen in love with sacred music and has told me many times before (as have her parents) that the Schola Cantorum has helped her grow much deeper not only in the knowledge of her Faith, but in her practice of it. These are not isolated instances.

The Most Pure Heart of Mary Schola Cantorum has obviously grown beyond any normal parish music program, and as part of our work to provide a solid financial basis for the program and to expand its outreach, we are asking individuals to consider making the Schola Cantorum part of their monthy giving, whatever that amount might be.

Please take a few minutes watch this short short video about the Schola Cantorum and consider helping our choristers, who might one day be bringing great sacred music to your parish:

Please note: When our Schola Cantorum sings for the Sacred Liturgy, we always use the organ. The music on this video was recorded during one of our daily rehearsals, so the piano is used.

Feel free to share this video with everyone you know! Thank you!

Simplified Accompaniment (Easter Hymn)

Number 36 in the Brébeuf Hymnal is “At the Lamb’s high feast we sing,” an English translation for Ad Cenam Agni Próvidi (which was called “Ad Régias Agni Dapes” starting 1631). As of this morning, you can download a simplified keyboard accompaniment for it. Simple click here and scroll to the bottom. Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult—which explains why choirmasters appreciate these simplified keyboard accompaniments. Sadly, many readers will click that link but forget to scroll to the bottom where the simplified PDF file is located.

PDF Download • “Quasi Modo Sunday”

The Introit for “Quasi Modo Sunday” (12 April 2026) is particularly beautiful. The musical score can be downloaded as a PDF file, and so can the organ accompaniment. The official language of the Catholic Church is Latin (whereas Greek is our mother tongue). Vatican II said Gregorian Chant must be given “first place” under normal circumstances. As a result, some parishes will rightly sing the authentic version. On the other hand, because so many USA dioceses disobey the mandate of Vatican II, some musicians sing plainsong in the vernacular. I have attempted to simultaneously accompany myself on the pipe organ while singing the English version. Although very few take advantage of it, the complete Proprium Missae is posted at the flourishing feasts website.

‘German’ Introductions for Hymns

German organ books have an enchanting habit of including introductions for each and every hymn. For example, consider this snazzy example found in a German hymnal published in 1902. In the Saint Jean de Brébeuf Hymnal, that melody is called “Laudes Mariae” and was married to Omni Die Dic Mariae, with a popular English translation (“Daily, daily, sing to Mary”) by Father Henry Bittleston, an Oratorian priest. Notice they also added a ‘tailpiece’ or ‘playout’ or postlude at the end—a very German thing to do!

PDF • “Liturgical Law” (467 Pages)

On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

“Gregorian Chant Quiz” • 24 March 2026

How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

PDF Download • “Ubi Caritas” (SATB)

I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.
