Video Demonstration Of Polyphony

Jeff Ostrowski · June 26, 2013

LL MY MASS SETTINGS were composed under certain constraints. It was necessary for them to be (1) relatively simple; (2) able to be sung with or without organ accompaniment; and, (3) within a “congregational” vocal range. Some might quibble with the notion that my Masses are “polyphonic,” since polyphony usually has more rests and slightly more independent vocal lines. A fairly nice definition of “polyphony” says that each voice has its own melody. In any event, I would submit that my Masses are as polyphonic as possible, given the restrictions I’ve already mentioned.

Below, I will provide links to everything required — SATB scores, organ scores, practice videos, and so forth. But first, please listen to these extremely short video demonstrations of polyphony:

* * Short Video Demonstration (1)

* * Short Video Demonstration (2)

Hopefully those videos provided a “taste” of the richness that is (I hope!) contained in each phrase of my Mass settings. You probably noticed that each phrase is “layered” — so there is always plenty to “listen for” no matter how many times the Mass is sung.

AS I PROMISED, below are the files for the SATB “Glory to God” in honor of Saint Edmund Arrowsmith. If you would like to download all four (4) of my Mass settings for the New Translation of the Roman Missal, please click here.

PDF Download • “Atténde Dómine”

Although it isn’t nearly as ancient as other hymns in the plainsong repertoire, Atténde Dómine, et miserére, quía peccávimus tíbi (“Look down, O Lord, and have mercy, for we have sinned against Thee”) has become one of the most popular hymns for LENT—perhaps because it was included in the famous Liber Usualis of Solesmes. This musical score (PDF file) has an incredibly accurate version in English, as well as a nice version in Spanish, and also the original Latin. Although I don’t claim to have a great singing voice, this morning I recorded this rehearsal video.

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!

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.
