I saw at Pray Tell a post about a new mass by Julian Revie called the “Mass of Welcome”. He is an award winning Australian-Canadian Catholic composer with an impressive body of work. I have listened to the mass and the first impression is of considerable ingenuity setting the poorly written text.
You can access the music by logging into Cloud Hymnal, although I found it rather annoying and less than intuitive. While I could see the piano arrangement I could only download the melody line. There are no chords on the music.
There are streaming music tracks there to learn to sing the parts of the mass.
I’m not doing the whole mass at present, but I’ve done a backing for the Gloria. I fed the music on the site through BIAB to get the chords and tried to see if it could survive my arrangement.
