Rehearsal Videos • Guerrero “Agnus Dei” (SSATB)

Jeff Ostrowski · May 17, 2017

NE OF THE MANY things participants will learn at the upcoming Sacred Music Symposium is how to produce rehearsal videos. Below you’ll find Guerrero’s AGNUS DEI (“Missa Iste Sanctus”) for which I recorded all the voices, including both Soprano lines. I usually apologize for my Soprano notes (I’m a Baritone), and there are two Soprano lines. But I’m not going to apologize twice—do you understand why?

REHEARSAL VIDEOS for each individual voice await you at #5512.

The internet has damaged the attention span of many people, and this can be a source of frustration to those of us who blog. I have frequently indicated a special website where you can sing along with each individual voice—yet many still do not realize what’s available there. So I will keep repeating it, and hopefully everyone will eventually bookmark that website.

By the way, that website also contains Mp3 files. YouTube compresses the audio files, making them sound horrible. The Mp3 versions sound much nicer.

“Music List” • 17th in Ordinary Time (Year C)

Some have expressed interest in perusing the ORDER OF MUSIC I prepared for the 17th Sunday in Ordinary Time (27 July 2025). 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 conveniently stored at the the feasts website.

Communion • “Ask & You Shall Receive”

All of the chants for 27 July 2025 have been added to the feasts website, as usual under a convenient “drop down” menu. The COMMUNION ANTIPHON (both text and melody) are exceedingly beautiful and ancient.

Pope Pius XII Hymnal?

Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.

“Hybrid” Chant Notation?

Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.

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).
