On leaving the Vatican after his abdication: “I was deeply moved. The cordiality of the farewell, also the tears of my collaborators. [His voice breaks with emotion.] On the roof of the Casa Bonus Pastor there was written in huge letters «Dio gliene renda merito» [“May God reward you”]. (The Pope weeps) I was really deeply moved. In any case, while I hovered overhead and began to hear the bells of Rome tolling, I knew that I could be thankful and my state of mind on the most profound level was gratitude.”
— Pope Emeritus Benedict XVI (23 May 2016)

Rehearsal Videos • A Resplendent “Agnus Dei” You've Never Heard
published 23 February 2016 by Jeff Ostrowski

URING the 1950s, Pope Pius XII added a special feast in honor of the Queenship of the Blessed Virgin Mary. 1 The antiphon for the Magnificat—“Beata Mater”—was not invented during the 1950s. It’s a very ancient chant, and Francisco Guerrero wrote an entire Mass based upon it. Throughout the various movements, Guerrero uses the CANTUS FIRMUS in clever ways, demonstrating his mastery of the “architecture” of large musical forms. 2 For example, the entire CREDO is a Canon between Soprano & Alto.

Can you hear what Guerrero does with the CANTUS FIRMUS (“Beata Mater”) in the final movement of this Mass? Do you see how he creates a perfect Canon between Soprano & Tenor?
