“Free” Is Better!

We’re currently learning Kevin Allen’s masterpiece for Soprano, Alto, and Bass: Quam Dilecta (setting the 1st verse of Psalm 83) from his Matri Divinae collection. Click here to hear a ‘live’ recording by a small group of singers. Click here to listen to a large choir singing it. And guess what? Rehearsal videos for each individual voice are completely free of charge! The Soprano rehearsal video is here. The “middle voice” (ALTO mixed with HIGH TENOR voices) is here. And the “Lowest” voice (BASS with LOW TENOR) is here.

Music List • (31st Sund. Ordinary Time)

This coming Sunday—3 November 2024—is the 31st Sunday in Ordinary Time, Year B. Some have expressed interest in perusing my “ORDER OF MUSIC.” If such a thing interests you, feel free to download it as a PDF file. The Offertory hymn we’re singing a cappella—set to the tune of FREUEN WIR UNS ALL IN EIN—is particularly beautiful. You’ll notice the Communion Hymn is for the SOULS IN PURGATORY, since November is their month.

“Entrance Chant” for Sunday (3-NOV-2024)

Download the Entrance Antiphon in English for the 31st Sunday in Ordinary Time (3 November 2024). It is based upon the original version, which the post-conciliar reformers borrowed from Wednesday in the 2nd week of Lent. This organ accompaniment corresponds to the vocalist score. If you’re someone who enjoys rehearsal videos, this morning I attempted to sing it while simultaneously accompanying my voice on the pipe organ.

Final Sundays after Pentecost

For those of us at a traditional Latin Mass, it’s that time of year when the sung propers for each Sunday repeat until the end of the liturgical year. What to do with the portion of your mid-week rehearsal that you normally devote to the next Sunday’s propers? I like to get a head start on propers for upcoming December feasts. We always sing Our Lady of Guadalupe on December 12 because she’s co-patroness of our diocese, and we sing a Rorate Mass in addition to Immaculate Conception. There’s also the first Sunday of Advent; it often follows Thanksgiving by a few days and we don’t rehearse on Thanksgiving. In short, there’s no reason to get bored at this time of year!

Parallel Fifths In Plainsong Accompaniment?

Parallel 5ths are forbidden in Baroque music and Classical music. However, plainsong accompaniment has its own rules and modal style. The great masters sometimes even wrote parallel sevenths! Instances of parallel fifths are too numerous to list in the Nova Organi Harmonia by the LEMMENSINSTITUUT. For example, consider this one. But one must possess a certain expertise to employ them properly. By the way, if you wish to see double parallel fifths, click here.

“Singing With The Girls”

A few months ago, I was brand new at my current church. At that time, we had no choir. However, attending the 5:00pm Mass were a few young ladies who sing very well. Right before Mass, we grabbed Kevin Allen’s collection: MOTECTA TRIUM VOCUM. I can’t remember if we had time to go over any of the songs. (If we did, we only went over them once.) Someone made a recording of us singing, and it actually sounds pretty good. I consider that piece—“Dómine, Non Sum Dignus”—to be a masterpiece. The version by Father Tomás Luis de Victoria is also quite beautiful, although the ranges are challenging in Victoria’s version.
