PDF Download • Organ Accompaniment for Kyrie VIII (“Missa de Angelis”) by Jeff Ostrowski

Jeff Ostrowski · August 23, 2022

HE FAMOUS “Mass of the Angels” (Missa de Angelis) often gets a bum rap. It’s certainly the most well-known Mass, and in the 19th century missions, it was sung in Iroquoian. People usually condemn it as being “too reminiscent modern tonality.” Even Dr. Peter Wagner placed it in the category of cantus recentiores. In reality, however, the Kyrie comes from the 1300s. The Sanctus and Agnus Dei are fairly ancient, too. They appear to be ‘contrafact’ settings of O Quam Suavis Est. (At the end of this article, I show some examples of that antiphon.) Anyone who’s skeptical is invited to examine this color-coded chart.

My Favorite Harmonization • Inspired by the great Flor Peeters, I have written an accompaniment for Kyrie VIII. In general, I move the bass-line downwards (stepwise) as the melody in the soprano rises.  I hope you like it:

That recording was made yesterday, which was the very first day our choir has returned. I think we’re going to have an awesome choral season!

President’s Corner

    “Yahweh” in church songs?
    My pastor asked me to write a weekly column for our parish bulletin. The one scheduled to run on 22 June 2025 is called “Three Words in a Psalm” and speaks of translating the TETRAGRAMMATON. You can read the article at this column repository. All of them are quite brief because I was asked to keep within a certain word limit.
    —Jeff Ostrowski
    “Music List” • Pentecost Sunday
    Some have expressed interest in perusing the ORDER OF MUSIC I prepared for Pentecost Sunday (8 June 2025). If such a thing interests you, feel free to download it as a PDF file. Because our choir is on break this week, the music is relatively simple.
    —Jeff Ostrowski
    “Truly Great Processional” • (Pipe Organ)
    I stumbled upon this live recording of a PROCESSIONAL I played on the pipe organ in 2002. It’s an excerpt from a much longer composition by Sebastian Bach. In those days, there weren’t sophisticated recording devices allowing one “fix” wrong notes. (Perhaps they existed, but we didn’t have machines like that.) So it was necessary to play the entire piece from beginning to end. If you’re a church organist, feel free to download the PDF score. I suppose it’s only a matter of time until some joker uses “artificial intelligence” to play music at church … but there’s something so satisfying about playing an organ in real life.
    —Jeff Ostrowski

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
