How I longed for the beautiful old hymns of the Roman Catholic Church to come back. We are Byzantine Catholics and are blessed with our Divine Liturgy which is entirely chanted and does not allow 'musical creativity', thanks be to God. However, on visits to Roman Catholic masses, I found that even when the old hymns were sung, most parishioners did not know them well.
Here is a wonderful site helping to remedy the situation:
If you sign up - for free - , the Traditional Catholic Living website and facebook page will teach you one traditional Catholic hymn per month with a beautiful PDF print out and audio to for those who don't read music. It cannot get any better than this. What a great homeschool resource.
