Ascension Day Music for the Mass

I've been tending to concentrate on the music for the Divine Office on this blog, mainly because there didn't seem to be much of anything on the web on the topic; not much that included Gregorian hymns, and audio files, anyway. And also, of course, because I love it, and do say and sing the daily prayers.

But in doing so, I've tended to neglect the music for the celebration of the Eucharist. So here's a link to the Mass Propers for Ascension (In Ascensione Domini), from the website of the Brazilian Benedictines, including the square note chant files in Latin. Below, as also discussed in my "Office Hymns for Ascension" post, is an audio file of the Introit for this mass, Viri Galilaei ("O men of Galilee"), sung by the "Schola of the Vienna Hofburgkapelle."



The text comes from Acts 1:11 and Psalm 47:1, and these are the Latin words, followed by the English:

Viri Galilaei, quid admiramini aspicientes in caelum?
Alleluia: quemadmodum vidistis eum ascendentem in caelum,
ita veniet, alleluia, alleluia, alleluia.

Omnes gentes plaudite manibus:
iubilate Deo in voce exsultationis.


Ye men of Galilee, why wonder you, looking up to heaven? alleluia. He shall so come as you have seen Him going up into heaven, alleluia, alleluia, alleluia.

O clap your hands, all ye nations; shout unto God, with the voice of exultation.

EDIT: In the comments, an anonymous poster has left two links to videos of two of the mass chants for Ascension: one to the Introit and the other to the Alleluia I.
