“Counter-Melody” for a Hymn Tune…

Jeff Ostrowski has added a “counter-melody” to CUPERTINO, a hymn tune composed by Kevin Allen. You can download the Organist Score (PDF), which doubles as the vocalist score. You can also hear Jeff’s volunteer choir sing that “counter-melody” version in real life by clicking here.

“The Use of Plainsong in Heretical Worship” • (Letter by Dom Gregory Murray)

“Unless Catholic musicians (especially priests) are careful, they may easily encourage non-Catholics in the belief that the differences between Catholics and non-Catholics are of minor importance.” —Dom Murray

Easter Sequence • “Both English and Latin”

Earlier this afternoon, I created an organ harmonization for the EASTER SUNDAY SEQUENCE: Víctimæ Pascháli Laudes in English and Latin. The rhythm conforms to the pure (“untouched”) Vatican Edition, like what you’d find in editions by Schwann, Monsignor Nekes, Max Springer of Beuron, and Peter Wagner (Commissionis Pontificiæ Gregorianæ Membrum). The beautiful and highly accurate […]

Theological…

The 330-page booklet for Sacred Music Symposium contains more than just fabulous and inspiring music. Little theological ‘tidbits’ cover its pages. For example, consider Page 265. You can download a PDF copy of the entire booklet at the Symposium website.

PDF • “For General Use Until Advent”

It’s based on the well known hymn tune: OLD HUNDREDTH. Rehearsal videos are available at #40691. A live recording of #40273 (“Adésto Sáncta Trínitas”) by […]

Introit • (This Coming Sunday)

Our volunteer choir appreciates training videos, so here’s my attempt at recording “Exáudi Dómine Vocem Meam,” which is the INTROIT for this coming Sunday. This coming Sunday is Dominica Post Ascensionem (“Sunday after the feast of the Ascension”). It is sung according to the official rhythm of the Catholic Church.

President’s Corner

    Bugnini’s Statement (6 November 1966)
    With each passing day, more is revealed about how the enemies of the liturgy accomplished their goals. For instance, Hannibal Bugnini deeply resented the way Vatican II said Gregorian Chant “must be given first place in liturgical services.” On 6 November 1966, his cadre wrote a letter attempting to justify the elimination of Gregorian Chant with this brazen statement: “What really gives a Mass its tone is not so much the songs as it is the prayers and readings.” Bugnini’s cadre then attacked the very heart of Gregorian Chant (viz. the Proprium Missae), bemoaning how the Proprium Missae “is completely new each Sunday and feast day.” There is much more to be said about this topic. Stay tuned.
    —Jeff Ostrowski
    Luis Martínez Must Go!
    Sevilla Cathedral (entry dated 13 December 1564): The chapter orders Luis Martínez, a cathedral chaplain, to stay away from the choirbook-stand when the rest of the singers gather around it to sing polyphony—the reason being that “he throws the others out of tune.” [Excerpt from “The Life of Father Francisco Guerrero.”]

Quick Thoughts

    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.

    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).

Random Quote

It was thought important that the song should actually accompany the distribution of Communion. A Carolingian explanation of the Mass remarks that during the Communion “soft melody should touch the ear [of the faithful] so that hearing this sound they would busy themselves less with distracting thoughts and … their hearts would be moved to humble love for that which they receive.”

— Father Josef Andreas Jungmann
