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.”

Gregorian Impressions • Plainchant Settings for Organ

Richard J. Clark · June 29, 2018

BRAND NEW release from The Sacred Music Press/The Lorenz Corporation, Gregorian Impressions is a collection of organ works based on familiar and beloved plainchants.

Shifting in character, they are designed to accommodate a variety of liturgical or concert circumstances. At the very least, this music can be performed on a two manual instrument with limited ranks. However, colorful registration, especially in animating chant melodies is encouraged on instruments with larger resources.

With intense dynamic and expressive intent, this collection cries out for the pipe organ to breathe and to sing.

PLAYLIST:


OWE A GREAT debt to Timothy E. Smith and Theodore Gilbert, builders of a unique instrument. Featured at several concerts during the 2014 National Convention of the American Guild of Organists and celebrated by the Boston Music Intelligencer as “Cavaillé-Coll-esque,” it is situated in one of the most glorious (and useful) acoustics in New England.

To the casual listener it is somewhat notorious for its power. But noted by every distinguished organist is the warmth and richness of its foundations and strings (voiced by Theodore Gilbert). More recent additions to the instrument by Timothy E. Smith have only added to the array of richness and color, seamlessly complimenting ranks with Gilbert’s voicing.

Such richness and warmth is certainly on display in these recordings, e.g., the introduction and coda of Veni, creator Spiritus or the building up of foundation stops and reeds on Jesu dulcis memoria.

None of this begins to speak of the highly pragmatic liturgical design of the instrument: foundation stops that speak clearly into the nave to support congregational singing, dynamic flexibility to accompany soloists, choral works, and chant, and an antiphonal division that unites a 19th Century architecture with the 21st Century liturgy. All of these necessary elements are the design and vision of Timothy E. Smith.

Finally, what is quite special to me, is not always the full array of the organ, but the quiet moments of reflection while composing and improvising. A few soft 8’ stops speak into an empty and darkened sanctuary, expressing most exactly what I ask. I thank God for an abundance of these moments for nearly twenty years. Such moments of musical and prayerful sanctuary have saved my life.

Soli Deo gloria

    Music List • (1st Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I’ve prepared for this coming Sunday—22 February 2026—the 1st Sunday of Lent (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 outstanding feasts website alongside the official texts in Latin. I spent an enormous amount of time preparing this ORDER OF MUSIC—because the children’s choir will join us—and some of its components came out great. For example, the COMMUNION ANTIPHON with Fauxbourdon is utterly resplendent, yet still ‘Lenten’.

    2-Voice Arrangement for Lent
    Those seeking a two-voice arrangement for LENT and PASSIONTIDE should click here and scroll down. It’s based on number 775 in the Brébeuf Hymnal, with an enchanting melody written by Kevin Allen (the legendary American composer of sacred music). That text—“Pendens In Crucis Cornibus”—is often used for the Feast of our Lady of Sorrows. That link is important because, in addition to the musical score, it provides free rehearsal videos for each individual voice: something volunteer choirs appreciate!

    “Sanctus VIII” • Organ Accompaniment
    A few days ago, I composed this organ harmonization for SANCTUS VIII. This Mass is traditionally called Missa de ángelis or “Mass of the angels.” In French, it is Messe de Anges. You can evaluate my attempt to simultaneously accompany myself on the pipe organ (click here) while singing the melody. My parish is currently singing this setting.

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”

    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.

Random Quote

“The following question is asked by the Most Reverend Lord Bishop of the Diocese of Chur: May this Diocese’s ancient custom be continued of having the Celebrant in Sung Masses (excepting more solemn Masses) intone the Credo and when he is finished reciting it going on immediately to the offertory and finishing it while the credo is being sung by the choir?” (Dubium of Dec 1909)
