Essentially the Missal of St. Pius V is the Gregorian Sacramentary; that again is formed from the Gelasian book which depends on the Leonine collection. We find the prayers of our Canon in the treatise “De Sacramentis” and allusions to it in the 4th century. So our Mass goes back, without essential change, to the age when it first developed out of the oldest liturgy of all. It is still redolent of that liturgy, of the days when Caesar ruled the world and thought he could stamp out the faith of Christ, when our fathers met together before dawn and sang a hymn to Christ as to a God. The final result of our enquiry is that, in spite of unsolved problems, in spite of later changes, there is not in Christendom another rite so venerable as ours.
— Fr. Adrian Fortescue (d. 1923)

Rehearsal Videos • Guerrero “Agnus Dei” (SSATB)
published 17 May 2017 by Jeff Ostrowski

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.
