A few years ago, I had valuable books stolen. Recovery efforts with law enforcement have failed, so I’m reaching out to our readers. Can somebody help me obtain VOLUME II and VOLUME VIII of the Nova organi harmonia published in the 1940s and 1950s by the LEMMENSINSTITUUT? As far as I can tell, these volumes can’t […]
Jeff, thanks for the rare Gregorian accompaniments. I just love all the work you do! About 2 years ago, my parish made the decision to ditch all the contemporary Mass settings (Marty Haugen, and so forth) and to only use the Latin! We currently use the [name redacted of a disposable missal] … some of their accompaniments […]
Dear Mr. Ostrowski; I must politely disagree with your friend who said “absolutely nobody cares” about the rare books you share on the blog. The fact is, your raw enthusiasm for these resources teaches me (and presumably others) to care. I admit that sometimes the angles from which you present them—the amount of context, or […]
Here’s a handy organ accompaniment (PDF) in three different key signatures: MIDDLE, HIGH, and LOW. The Latin lyrics (“Silens Nox”) are courtesy of Father Valentine Young, OFM (d. 2020). The organ harmonies are very simple, yet beautiful. Those who desire such a thing may also download a Singer’s Version. For obvious reasons, the choir will […]
A very skilled conductor from another country—who recently posted a recording any conductor would be proud of, displaying a light, pleasant, and professional choral sound—wrote to us on 23 December 2022: “CCWatershed and the Sacred Music Symposia have made a great mark in my musical career and the sound you hear you can proudly say […]
People often ask: “Can Gregorian Chant include the congregation?” The answer is: Yes! Listen to this Live Recording from last Sunday (which was the 4th Sunday of Advent). That is one model—not the only model—demonstrating how a congregation could be included. It’s KYRIE XVII, traditionally sung during Advent.

Dr. Aaron James, who earned a double doctorate, has stated publicly that the Saint Jean de Brébeuf Hymnal does a wonderful job explaining—by means of gorgeous color plates—the difference between the “Pre-Urbanite” hymns and those which were modified by Pope Urban VIII (d. 1644). Dr. James calls the Brébeuf treatment of the urbanite reform “a […]

“I can’t thank you enough for that four-part download of the Graduale with 5 lines. That is absolutely brilliant! Since I and another guy from the choir chant the Traditional Propers every Sunday, it has proven to be an invaluable resource. Great job of scanning it, too.” —Email received this morning from S.M.D.
Those who accompany VESPERS FOR THE FIRST SUNDAY OF ADVENT may wish to download this draft copy. It’s the organ accompaniment I use, since my parish has Vespers (in the Extraordinary Form) with our congregation each Sunday afternoon. It looks pretty ‘junky’ but it gets the job done. Someday I hope to make a much […]
We have posted many articles discussing the French Vs. German way of interpreting syllabic plainsong—which some refer to as “Trochee Trouble.” Needless to say, we encourage everyone to carefully read all those articles. But some folks still don’t understand what “Trochee Trouble” is all about. Therefore, I have created this 1-Page Sheet that explains it […]
