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.”

Blackley’s Sunday Mass Propers Now Available as Free PDF

Patrick Williams · February 25, 2023

OHN BLACKLEY has recently published a 503-page PDF titled Laon 239: Chant Transcriptions in Proportional Rhythm, English & Latin, which may be of interest to many readers. His older articles, “On Realizing Gregorian Chant” and “Rhythm and Nuance in Chant,” are archived here. In this new volume commemorating the 50th anniversary of his Schola Antiqua, Blackley reveals a bit more about himself than I remember from his previous writings, namely that he belonged to a Catholic religious order for some time, the Christian Brothers, and conducted according to the Solesmes method while in the order (p. 481) and that he apparently now identifies more closely with “those of us on the outskirts of Christianity” than “those within Christianity” (p. 485). He writes, “Back in New York City, decades ago, we sang weekly Masses not necessarily as believers but as appreciators of Poetry [sic] in music & texts. Masses were sung through the liturgical year to celebrate a mythos of the rabbi Jesus in history & mystically” (p. 4). Now that that cat is out of the bag, let’s consider his technical approach to the chant.


Gradual for Maundy Thursday (p. 189)

Literalism and Syncopation • Blackley transcribes Laon 239 literally—perhaps too literally. In reference to David Hiley, Blackley writes, “Not he nor any semiologist nor anyone associated with Solesmes will face what is obvious among the shapes of the ninth-& tenth-century written musical signs: the ordinary sung note is a long that is divisible!” (p. 500), which is precisely the position I also articulated in a recent post. Unfortunately, Blackley himself has also failed to face something obvious in the adiastematic neumes, namely, that short notes generally appear only in pairs or other even-numbered quantities, with relatively few exceptions. Although he reproduces the significative letters such as c, t, and a, Blackley simply writes a short note in some instances where other editors, considering the evidence of tenth-century manuscripts besides Laon 239, prefer a weak beginning (initio debilis) grace note. The plain short note, sung as written, results in a ternary rhythmic group. Rather than a sort of holdover from the Solesmes method, such ternary groupings represent willingness to admit disruption of the tactus equal to one long note and, more broadly speaking, an unnecessary degree of syncopation (which can be heard in Schola Antiqua’s recordings). The work of Jan van Biezen, whose Rhythm, Meter and Tempo in Gregorian Chant Blackley includes in his bibliography, offers a corrective in regard to these apparent syncopations, with an approach that incorporates Cardine’s insights into a mensuralist framework consistent with the oldest extant sources and the medieval writers. Elsewhere, when a weak beginning note is clearly indicated in the Laon codex itself, Blackley uses a round note (e.g., at terra on p. 34 and figures e, j, k, l, and n on p. 478).

Worksheet for Midnight Mass (p. 42)

Curiosities • Blackley includes some drafts, comparative tables, and duplex editions that result in a more interesting presentation than merely including the handwritten performing editions in both Latin and English. From a few cursory glances, I note that an elegant style of early modern English is used, but with Adonai instead of Lord in many instances where Domine represents the Tetragrammaton; for example, “Thou hast shown unto me the way of life: thou wilt fill my soul with joy in the sight of thy face, Adonai” (p. 93). My only complaint with the notation itself is the inconsistent use of the custos or guide note. In some chants, it is omitted altogether; elsewhere, it appears at the right margin, where it ought to be, or at the right edge of unjustified musical lines. I also question his claim (as well as Jan van Biezen’s) that each syllable of psalm recitation in the Divine Office should have the value of a long note (p. 12), just like the introit verses of the Mass. Van Biezen’s translator, Kevin M. Rooney, mentions in a footnote that

Actually, the Commemoratio brevis calls for an exception in the canticles, the Benedictus and Magnificat, “which are sung so slowly that their antiphon should follow at the same tempo” (tr. Terrence Bailey, Commemoratio brevis de tonis et psalmis modulandis, p. 107). Since the psalm verses of Introit and Communion show the same solemnity of decoration as the canticles, it follows that they too are to be sung at the same tempo as their antiphons, i.e. half the tempo of the normal psalm verses. (“The Rhythm of Gregorian Chant” in Rhythm, Meter and Tempo in Gregorian Chant, p. 41)

Communion for Easter Sunday, in English (p. 241)

Thank you, sir! • As in his previous writings, besides the musical content, Blackley offers equally valuable personal anecdotes and impressions. On p. 491, he mentions how Vollaerts and probably Murray as well were pressured by their superiors to stop teaching the proportional rhythm of the Middle Ages—which is a good reminder that we need ordinary lay people involved in this important work. Blackley’s editions are clearly the result of years of painstaking labor. I wholeheartedly commend him for making them available to the world for free. I conclude this post with his own words stressing the importance of musicality in addition to accurate performing editions: “Transcriptions are best done by those who both sing & conduct and enjoy studying minute neumatic details & problems—all this while making sure that the horizontal musical line of each song is their main musical concern” (p. 52).

    Music List • (3rd Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday: the 3rd Sunday in Ordinary Time (Year A). 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 available at the monumental feasts website alongside the official texts in Latin.

    “Holy Name Hymn” (2-Voice Arrangement)
    When we post a direct URL link, we frequently get thousands of downloads. But when scrolling is required, very few take the time. I mention this because those who click on this URL link and scroll to the bottom can download—completely free of charge—a clever 2-voice arrangement for a famous hymn to the Most Holy Name of Jesus. In a pinch, it can be nicely sung by one male and one female! It will be of interest to those who seek arrangements for two voices.

    PDF Download • Introit (3rd Sn. Ord.)
    This coming Sunday, 25 January 2026, is the 3rd Sunday in Ordinary Time (Year A). The ENTRANCE CHANT (“Dóminus secus mare”) is somewhat rare because it comes from the New Testament. The authentic version in Latin—of astounding antiquity—was jettisoned in 1955 but restored in 1970. This rehearsal video has me attempting to sing the melody while simultaneously accompanying myself on the organ. I encourage you to print off the organ accompaniment (PDF) and play through it because it has extremely ‘happy’ harmonies.

    “Reminder” — Month of January (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.

Random Quote

The union of Christians can only be promoted by promoting the return to the one true Church of Christ of those who are separated from it, for in the past they have unhappily left it.
