Calling Dr. Weaver!

A remarkable exposition of the “mora vocis” (published in 1953 in the Netherlands) which doesn’t shy away from a certain item!

    Garnier Alleluias • “Have They Moved?”
    We received an email asking whether the GARNIER GOSPEL ACCLAMATIONS website has moved. [This also concerns the HARD COPIES button at the top, which everyone should take note of.] As far as I can see, it remains in the same location it always has. One can also reach these settings through a different route, namely via the flourishing feasts website (although that website isn’t quite as active during summer months).
    —Jeff Ostrowski
    Absolutely ‘Perfect’ Voice-Leading?
    I love when a passage employs many different harmonies (instead of alternating back-and-forth between the same three chords). I also relish counterpoint: a skillful mixture of similar, oblique, and contrary motion. This little passage seems, in my humble opinion, utterly splendid. It has powerful contrary motion—as well as oblique motion—and nice STIMMTAUSCH (“voice exchange”). It also exhibits thoughtful interplay of consonance and dissonance.
    —Jeff Ostrowski
    Calling Dr. Weaver!
    I believe Dr. Charles Weaver will be interested in this! Published in the Netherlands in 1953, it explains how the mora vocis is treated by the official edition. It even treats the PONS ASINORUM: viz. the “mystery virga” added by the Vatican Commission on Gregorian Chant—which was not found in any previous edition by Dom Pothier. You can download this 1953 document (PDF), with a rough translation from Dutch into English. For the record, one particular sentence (“Gregoriaanse volkzang is massazang”) is difficult to interpret. Are there any Dutch speakers out there? They reference melismata when they say: “if two notes stand over a single syllable.”

Quick Thoughts

    “Predictable Rhymes?” • A Follow Up
    We received considerable correspondence regarding my article, Two Ways to Defile a Hymn. More specifically, what really raised certain people’s hackles was its follow-up article dealing with the keyboard accompaniment for the CHRIST THE KING HYMNAL. But to quote Eliza Doolittle: “Have I said anything I oughtn’t?” Please examine this PDF file and see whether you agree. Were the editors of the BRÉBEUF HYMNAL incorrect to insist upon sophisticated and clever rhymes, rather than mind-numbingly predictable rhymes?
    —Jeff Ostrowski
    ‘Ould’ But Not Good
    Dom Samuel Gregory Ould (note the spelling) was a Benedictine monk at FORT AUGUSTUS ABBEY in Scotland. As musician, organist, and composer, Dom Ould was highly regarded. Moreover, he was considered an authority on Gregorian Chant. But not everything found in an old book—or, in this case, an “Ould” book—is necessarily praiseworthy. Consider this page from Dom Ould’s hymnal. Do you see the rhymes? They offend severely by ABR (“Abuse By Reuse”) and are utterly predictable. In my recent article—Two Ways to Defile a Hymn—I addressed this topic.

    “Reader Feedback” • 22 June 2026
    A reader wrote to us from Virginia: “I really appreciate the 23 harmonizations that you posted on CORPUS CHRISTI WATERSHED for the Daily, Daily, Sing to Mary hymn. I hope to find willing voices in our small Schola Cantorum to try the three-voice version. Carry on, sir! You’re doing the Lord’s work.” While we don’t know this gentleman personally, we note that he earned a Ph.D. (which demonstrates that our blog has something for everybody). 😊

Random Quote

It is known that the “mora vocis” is part of the compulsory rules of recital of the “Vaticana” and is indicated in the Editio typica and its reprints by a somewhat larger spacing of the neume (one space-line) within one group of neuma.
