I just stumbled across the blog of the Church Music Association of America (found it through Stella Borealis). I was surprised to find that Dr. William Mahrt is the president of the association. I was priviledged to sing in Dr. Mahrt's choir during my summers home from college. Looks like this is a good place to do some more digging.
I'm scheduled to do a little music workshop for a parents' meeting for our homeschool group early next year. The main objectives are to promote the importance of helping young people appreciate these treasures of the Church (though I'll only spend a little time on this) and teach everyone to sing perhaps three or four pieces (at least half of them will be Gregorian Chant). Hope to display a selection of useful resources as well. We're inviting teens to attend as well. Hope it'll be a fun evening. Suggestions welcome!
