Corpus Christi Watershed

Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”

    A Nice Hymn In Spanish
    In my humble opinion, this is a really beautiful hymn in Spanish. If I practice diligently, I’ll be able to pronounce all the words properly. If you’re someone who’s interested in obtaining a melody only version (suitable for your congregational ORDER OF WORSHIP) you can steal that from this.
    —Jeff Ostrowski
    “Music List” • 21st in Ordinary Time (Year C)
    Our choir returns on Sunday, 24 August 2025. Some have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for it, which is the 21st Sunday in Ordinary Time (Year C). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the spectacular feasts website. When it comes to the feast of the Assumption (15 August 2025), I have uploaded the music list for that Mass—but not the “bi-lingual” Mass in the evening (Spanish, Latin, and English) which has completely different music.
    —Jeff Ostrowski
    “Entrance Chant” • 21st Sunday Ordin. Time
    You can download the ENTRANCE ANTIPHON in English for the 21st Sunday in Ordinary Time (Year C) which is coming up on 24 August 2025. Corresponding to the vocalist score is this free organ accompaniment. It’s set in a melancholy mode, but if you heard my choir’s female voices singing it your soul would be uplifted beyond belief. If you’re someone who enjoys rehearsal videos, this morning I tried to sing it while simultaneously accompanying my voice on the pipe organ.
    —Jeff Ostrowski

Quick Thoughts

    Solemn “Salve Regina” (Chant)
    How many “S” words can you think of using alliteration? How about Schwann Solemn Salve Score? You can download the SOLEMN SALVE REGINA in Gregorian Chant. The notation follows the official rhythm (EDITIO VATICANA). Canon Jules Van Nuffel, choirmaster of the Cathedral of Saint Rumbold, composed this accompaniment for it (although some feel it isn’t his best work).

    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.
    —Corpus Christi Watershed
    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.
    —Corpus Christi Watershed

Random Quote

The ratio of voices in modern choirs is usually wrong. Basses should be numerically greatest, then altos, then tenors, then sopranos. One good soprano can carry a high “A” against 30 lower voices.
