(29 Pages) • Free Organ Accompaniment Book — Draft copy

Jeff Ostrowski · July 31, 2021

ECENTLY, I posted a Vespers Booklet for this coming Sunday, 1 August 2021, which is the 10th Sunday after Pentecost. That was the booklet for singers—and by “singers,” I mean the entire congregation. Approximately 1,300 souls attend the Traditional Latin Mass at my parish in Los Angeles each Sunday … and many stay until Sunday afternoon to sing Vespers. The following is what I will use to accompany the congregation tomorrow. You will see much was “borrowed” from the Nova Organi Harmonia. Each week, I hope to make small improvements. Perhaps in a year’s time, the book will be “perfect”—but for now, this will have to do:

“Yahweh” in church songs?

My pastor asked me to write a weekly column for our parish bulletin. The one scheduled to run on 22 June 2025 is called “Three Words in a Psalm” and speaks of translating the TETRAGRAMMATON. You can read the article at this column repository. All of them are quite brief because I was asked to keep within a certain word limit.

“Music List” • Pentecost Sunday

Some have expressed interest in perusing the ORDER OF MUSIC I prepared for Pentecost Sunday (8 June 2025). If such a thing interests you, feel free to download it as a PDF file. Because our choir is on break this week, the music is relatively simple.

“Truly Great Processional” • (Pipe Organ)

I stumbled upon this live recording of a PROCESSIONAL I played on the pipe organ in 2002. It’s an excerpt from a much longer composition by Sebastian Bach. In those days, there weren’t sophisticated recording devices allowing one “fix” wrong notes. (Perhaps they existed, but we didn’t have machines like that.) So it was necessary to play the entire piece from beginning to end. If you’re a church organist, feel free to download the PDF score. I suppose it’s only a matter of time until some joker uses “artificial intelligence” to play music at church … but there’s something so satisfying about playing an organ in real life.

Antiphons Don’t Match?

A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).

When to Sit, Stand and Kneel like it’s 1962

There are lots of different guides to postures for Mass, but I couldn’t find one which matched our local Latin Mass, so I made this one: sit-stand-kneel-crop

The Funeral Rites of the Graduale Romanum

Lately I have been paging through the 1974 Graduale Romanum (see p. 678 ff.) and have been fascinated by the funeral rites found therein, especially the simply-beautiful Psalmody that is appointed for all the different occasions before and after the funeral Mass: at the vigil/wake, at the house of the deceased, processing to the church, at the church, processing to the cemetery, and at the cemetery. Would that this “stational Psalmody” of the Novus Ordo funeral rites saw wider usage! If you or anyone you know have ever used it, please do let me know.

—Daniel Tucker

“We must say it plainly: the Roman rite as we knew it exists no more. It has gone. Some walls of the structure have fallen, others have been altered—we can look at it as a ruin or as the partial foundation of a new building. Think back, if you remember it, to the Latin sung High Mass with Gregorian chant. Compare it with the modern post-Vatican II Mass. It is not only the words, but also the tunes and even certain actions that are different. In fact it is a different liturgy of the Mass.”

— Fr. Joseph Gelineau (1978)
