“Sacred music, being a complementary part of the solemn liturgy, participates in the general scope of the liturgy, which is the glory of God and the sanctification and edification of the faithful. It contributes to the decorum and the splendor of the ecclesiastical ceremonies, and since its principal office is to clothe with suitable melody the liturgical text proposed for the understanding of the faithful, its proper aim is to add greater efficacy to the text, in order that through it the faithful may be the more easily moved to devotion and better disposed for the reception of the fruits of grace belonging to the celebration of the most holy mysteries.”
— Pope Saint Pius X

“Creator Alme Siderum” (Guerrero)
published 7 December 2017 by Jeff Ostrowski

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.
