Jesus said to them: “I have come into this world so that a sentence may fall upon it, that those who are blind should see, and those who see should become blind. If you were blind, you would not be guilty. It is because you protest, ‘We can see clearly,’ that you cannot be rid of your guilt.”

Jeff Ostrowski · January 17, 2024

OR MANY YEARS, I had no idea how to use the Gregorio software (a.k.a. “GABC”) to instantly create plainsong scores on the computer. When I couldn’t take it anymore, I called up a friend and paid him $150 to teach me over the telephone. I was able to learn only with assistance from a living, breathing human being. Thanks to his assistance, I can now create Gregorian Chant scores with ease. That $150 was not wasted. Some things in life (in my humble opinion) cannot be learned from books—and that’s why I recently recorded a special seminar: Secrets of the Conscientious Choirmaster.

Contrafactum • Nothing is hard if you know how to do it. Men who spent their entire lives tinkering with automobiles and tractors have no problem repairing cars—because they know what to do! In my seminar, I give away secrets I’ve picked up over the last 25 years (working with hundreds of singers across the United States). One technique I really “hammer” or “emphasize” or “highlight” is that of CONTRAFACTUM. I don’t see how anyone could run a choral program without it. Mozart used it. Handel used it. Bach used it. Even Father Cristóbal de Morales (d. 1553) used CONTRAFACTUM when he wrote alternate movements for his magnificent Missa Mille Regretz.

Choral Extensions • I also delve into the concept of “choral extensions” during my seminar. To give you an example, yesterday afternoon I quickly threw together—thanks to the Missa Mille Regretz by Father Cristóbal de Morales—a “polyphonic extension” using CREDO III:

What We Did • Several of my choir members helped me record it—so you can get a rough idea how the “choral extension” sounds:

Free rehearsal videos for each individual voice await you at #34648.

Jeff’s Sadness:

Free rehearsal tracks for each individual voice are available at that link, but most readers won’t click on it—and that makes me feel depressed. They take forever to create, but the choirmasters who utilize them testify they’re worth their weight in gold.

P.S.
Father Morales does some nifty things in that polyphonic “Et Incarnatus Est.” You can learn more if you watch the INTRODUCTION (51 minutes) which is available free of charge.

    “Music List” • 5th Sunday of Easter (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I prepared for the 5th Sunday of Easter (18 May 2025). If such a thing interests you, feel free to download it as a PDF file. The Communion Antiphon was ‘restored’ the 1970 Missale Romanum (a.k.a. MISSALE RECENS) from an obscure martyr’s feast. Our choir is on break this Sunday, so the selections are relatively simple in nature.

    Communion Chant (5th Sunday of Easter)
    This coming Sunday—18 May 2025—is the 5th Sunday of Easter, Year C (MISSALE RECENS). The COMMUNION ANTIPHON “Ego Sum Vitis Vera” assigned by the Church is rather interesting, because it comes from a rare martyr’s feast: viz. Saint Vitalis of Milan. It was never part of the EDITIO VATICANA, which is the still the Church’s official edition. As a result, the musical notation had to be printed in the Ordo Cantus Missae, which appeared in 1970.

    “Music List” • 4th Sunday of Easter (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I prepared for the 4th Sunday of Easter (11 May 2025). If such a thing interests you, feel free to download it as a PDF file. I don’t know a more gorgeous ENTRANCE CHANT than the one given there: Misericórdia Dómini Plena Est Terra.

Quick Thoughts

    Antiphons Don’t Match?
    A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).

    When to Sit, Stand and Kneel like it’s 1962
    There are lots of different guides to postures for Mass, but I couldn’t find one which matched our local Latin Mass, so I made this one: sit-stand-kneel-crop
    —Veronica Brandt
    The Funeral Rites of the Graduale Romanum
    Lately I have been paging through the 1974 Graduale Romanum (see p. 678 ff.) and have been fascinated by the funeral rites found therein, especially the simply-beautiful Psalmody that is appointed for all the different occasions before and after the funeral Mass: at the vigil/wake, at the house of the deceased, processing to the church, at the church, processing to the cemetery, and at the cemetery. Would that this “stational Psalmody” of the Novus Ordo funeral rites saw wider usage! If you or anyone you know have ever used it, please do let me know.
    —Daniel Tucker
