Can You Spare 33 Seconds?

Here’s an audio excerpt (33 seconds) of a setting for Kyrie VIII which was recorded live last Sunday at our parish in Los Angeles. The setting (“Missa de Angelis”) is by composer Richard Rice, and you can download the free PDF if you click here and scroll to the bottom. I think Richard’s composition is marvelous. I missed a few notes on the organ, but I’ll get them right next time.

5 April 2021 • When Girls Sing

Covid restrictions here in California are still extremely severe—switching “two weeks to flatten the curve” into “two years to flatten the curve.” Since 2020, we’ve had police breaking into our church to check if everyone is wearing a mask…even when only 5-6 people are present! But we were allowed to have a small percentage of our singers back on Easter Sunday, and here is their live recording of the ancient Catholic hymn for Eastertide: Ad Cenam Agni Providi. The girls were so very excited to sing again—you can hear it in their voices!

29 March 2021 • FEEDBACK

“E.S.” in North Dakota writes: “I just wanted to take a moment to say THANK YOU for all the hard work you have put—and continue to put—into your wonderful website. In the past two years, my parish has moved from a little house basement into a brand new church and gone from a few families receiving Low Masses twice a month to several families (and many individuals) receiving Mass every Sunday, two Saturdays a month, and every Holy Day. Our priest has been incorporating more and more High Masses and various ceremonies into our lives, which has made my job as a huge newbie choir master very trying and complicated. CCWatershed has been an invaluable resource in helping me get on my feet and know what to do!!! Thank you more than I can express! May God bless you abundantly and assist you in your work and daily lives!”

Giovanni Doni is known for having changed the name of note “Ut,” renaming it “Do.” He convinced his contemporaries to make the change by arguing that 1) “Do” is easier to pronounce than “Ut,” and 2) “Do” is an abbreviation for “Dominus,” the Latin word for the Lord, Who is the tonic and root of the world. There is much academic speculation that Giovanni Doni also wanted to imprint himself into musical canon in perpetuity because “Do” is also ulteriorly an abbreviation for his family name.

— Giovanni Battista Doni died in 1647AD
