President’s Corner

    “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
    Proof Which All Can Immediately See!
    “A little knowledge is a dangerous thing,” as the famous maxim goes. Over the years, I’ve observed malicious attacks on the Brébeuf Catholic Hymnal. Rather than scoring a ‘hit’ on the Brébeuf Hymnal, its attackers often reveal profound ignorance. I’ve been advised never to reply … but I break that rule today. Certain voices online assert that the Brébeuf Hymnal is “untraditional” because it includes both the Urbanite and pre-Urbanite versions of the hymns. But if only they would glance at a copy of the 1913 VESPERALE (printed by order of Pope Saint Pius X) they would see how mistaken such statements are.
    —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).
    —Corpus Christi Watershed
    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

The “Nova Organi Harmonia” demanded from each of us an unusual commitment; we have dedicated to it the best of our energies. Would it be, therefore, presumptuous on our part to be satisfied with the result and to expect its welcome reception in the musical world?

— Msgr. Jules Van Nuffel (circa 1940)
