“Creator Alme Siderum” (Guerrero)

Jeff Ostrowski · December 7, 2017

UR READERS are undoubtedly familiar with the ancient Advent hymn: Creátor alme síderum. The original title was Cónditor alme síderum, but four Jesuits working for Pope Urban VIII (d. 1644) wrecked most of the Breviary hymns—causing endless confusion. Correct accentuation is crucial since CÓNDITOR means “maker” whereas CONDÍTOR means “pickler.”

The famous tune can be played on this Woofer Guitar:


Before you listen to the full version by Guerrero, explore the Tenor and Soprano only:


Do you see the beautiful counterpoint with just two voices? In real life, one hears clearly the different vocal sections, and the counterpoint sounds awesome. In a YouTube version, however, the voices sound “flattened.”

I couldn’t resist recording it, even though my voice singing all the parts never sounds quite right:

The tempo could probably be slightly slower, but I don’t recommend taking it so slowly that the plainsong in the Soprano line becomes difficult to recognize.

Quick Thoughts

19 May 2022 • “Trochee Trouble”

I’m still trying to decide how to visually present the “pure” Editio Vaticana scores, using what is (technically) the official rhythm of the Church. You can download my latest attempt, for this coming Sunday. Notice the “trochee trouble” as well as the old issue of neumes before the quilisma.

16 May 2022 • Harmonized Chant?

This year’s upcoming Sacred Music Symposium will demonstrate several ways to sing the CREDO at Mass. This is because—for many parishes—to sing a full-length polyphonic CREDO by Victoria or Palestrina is out of the question. Therefore, we show options that are halfway between plainsong and polyphony. You can hear my choir rehearsing a section that sounds like harmonized plainsong.

14 May 2022 • “Pure” Vatican Edition

As readers know, my choir has been singing from the “pure” Editio Vaticana. That is to say, the official rhythm which—technically—is the only rhythm allowed by the Church. I haven’t figured out how I want the scores to look, so in the meantime we’ve been using temporary scores that look like this. Stay tuned!

Random Quote

No concession should ever be made for the singing of the Exsultet, in whole or in part, in the vernacular.
