Quick Thoughts

PDF Download • Trinity Sunday (22 pages)

Feel free to download this Organ Accompaniment Booklet for Trinity Sunday (Second Vespers). Notice how the modes progress by number. Psalm 1 is mode 1; Psalm 2 is mode 2; Psalm 3 is mode 3; Psalm 4 is mode 4; Psalm 5 is mode 5. I am told by an expert that other feasts (such as Corpus Christi) are likewise organized by mode, and it’s called a “numerical office.”

10 June 2022 • “Official” rhythm of plainsong

I continue to search for the most beautiful way to present the “pure” Editio Vaticana scores. (Technically, the “pure” rhythm of the official edition is what everyone is supposed to use.) You can download my latest attempt, which is the Introit for this coming Sunday: Feast of the Most Holy Trinity. Because this is not an ancient feast, the Introit had to be adapted (perhaps around 750AD). Prior Johner says the adaptation is “not an entirely happy one.”

7 June 2022 • FEEDBACK

From Chelan, Washington: “CCWatershed is a God-sent resource that I can’t function without! Such great work by the team to bring beauty back to our liturgy!” From Gainesville, Florida: “I am so appreciative of the work, of my brothers and sisters in music!” From Troutman, North Carolina: “Keep up the excellent work in service of the Liturgy!”

Random Quote

I feel the greatest destroyer of peace today is abortion, because it is a direct war, a direct killing—direct murder by the mother herself. And we read in the Scripture, for God says very clearly: “Even if a mother could forget her child, I will not forget you: I have carved you in the palm of my hand.”

— Mother Theresa (11 Dec 1979)
