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.”

Does Polyphony “Fit” Ordinary Form Masses?

Jeff Ostrowski · July 11, 2017

URING THE SACRED MUSIC SYMPOSIUM, I described how to painlessly add polyphony to the Ordinary Form by “sneaking it in” with choral extensions. So much information was shared during our conference—from 7:30am until 9:30pm each day, literally—that I wasn’t able to spend sufficient time explaining.

Therefore, I’ve created this video:

REHEARSAL VIDEOS for each individual voice await you at #4884.
As always, the PDF score can be downloaded there, too.

IF YOU DON’T HAVE enough voices to do the example above, consider the following: Guerrero “Iste Sanctus” (#5294); Palestrina Short (#6482); Palestrina Longer (#6995); Guerrero “Beata Mater” (#3347, #3661, #3579); Durieux (#4638); Palestrina “Impleta sunt” (#5053, #5054); Brudieu (#4327).

The Mass setting in the video is from Victoria’s Officium Defunctorum. This is a famous piece, and I was too scared to “vandalize it” by transposing it up a whole step—but my choir will most likely do so. Fr. Victoria’s work is based on the Requiem KYRIE, so I could have chosen the plainsong accordingly, but only if we were singing it for an actual Requiem. Despite what some assert, these are not rigid rules that can’t be changed. For example, most editors choose Mode II for Allegri’s Miserere Mei, but the actual music is based on the Tonus Peregrinus. Indeed, Sanctus VIII was taken verbatim from O Quam Suavis Est; but does that mean Sanctus VIII can only be sung on feasts where that Antiphon is employed? I think not.

I recorded all the voices for the above video except the third section, which was recorded by volunteers at Sacred Music Symposium 2017. Can you hear the difference? Listen closely to the richness in the third section, which begins at the 2:17 marker.

Don’t expect the congregation to understand immediately when they are supposed to sing. It will take at least a year before they begin to understand. At the Symposium, we spoke of the importance of using the same structure every Sunday for a long time before the good fruits become evident. That is why I would never dream of introducing the propers at OF Masses unless the congregation had a book such as the Isaac Jogues Pew Lectionary, which has 100% of the propers in Latin and English. I repeat: it takes years to reintroduce authentic liturgy, because our people have been robbed for half a century.

    “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

Random Quote

Benedict XVI in particular felt it was wrong to prohibit the celebration of Mass in the ancient rite in parish churches, as it is always dangerous to corner a group of faithful so as to make them feel persecuted and to inspire in them a sense of having to safeguard their identity at all costs in the face of the “enemy.”

— Archbishop Georg Gänswein
