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.”

“Homily — Feast of the Holy Family, Year B” • Father Valentine Young, OFM

I can speak mainly from my experience with Indians, more specifically the Navajos; their native culture has a great respect and love for marriage and family life.

Chasing the Little Office of the Blessed Virgin Mary

I thought making a course on singing the Little Office would be an easy project. However, as with just about everything to do with Sacred Music, there is so much more to it than you expect.

23 December 2020 • A 5th? or 4th?

I have noticed that where the Editio Vaticana has a descending perfect fourth for the Gradual of Christmas Midnight Mass, many ancient manuscripts have a descending perfect fifth, which is pretty cool: Example A — Example B. The Vatican Edition is a CENTO, and never made any claim to be anything other than a CENTO. […]

“Blessing the Bell” • Most Rev’d Alejandro D. Aclan

When a monk hears the bell, he stops whatever he’s doing and immediately goes to prayer. It is the voice of God calling us to pray, to avoid sin, and to forget the things of this world and think of Him.

    Music List • “5th Sunday of Easter” (Year A)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for the 5th Sunday of Easter Sunday—a.k.a. “Dominica V Paschae”—which is 3 May 2026. Please feel free to download it as a PDF file if such a thing interests you. The COMMUNION (“Tanto Témpore Vobíscum Sum”) is rather somber, with awesome fauxbourdon psalm verses. The ENTRANCE CHANT is bright and happy.

    PDF Download • Communion for Sunday
    The COMMUNION ANTIPHON with fauxbourdon psalm verses for this coming Sunday (3 May 2026) is elegant and poignant. It’s such a shame it only comes every three years. This piece—along with all the musical scores for this coming Sunday, which is the 5th Sunday of Easter (Year A)—can be downloaded free of charge from the flourishing feasts website. By the way, how is it already 2026?

    Season’s End Repertoire
    Looking at the REPERTOIRE SHEET until the end of the choral season, I see that I’ve fallen behind schedule. (The last three months have been extraordinarily busy.) As you know, I have been providing organ harmonies for all the ENTRANCE CHANTS—as well as rehearsal videos—and you can see I’m behind where I planned to be. Now I must make up lost ground. However, the choir picks up the ENTRANCE CHANT with ease, so I’m sure it will all work out. My ‘unofficial’ harmonizations are being posted each week at the flourishing feasts website.

Quick Thoughts

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

    PDF • “Liturgical Law” (467 Pages)
    On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

Random Quote

“The Pope is not an absolute monarch whose thoughts and desires are law. On the contrary: the Pope’s ministry is a guarantee of obedience to Christ and to his Word. He must not proclaim his own ideas, but rather constantly bind himself and the Church to obedience to God’s Word, in the face of every attempt to adapt it or water it down, and every form of opportunism.”

— ‘His Holiness, Pope Benedict XVI (11 May 2005)’
