The choir loft at my church has two closets which are filled with everything from 70's hymnals to old door frames. This morning I was clearing out some of the 70's hymnals when I found a thick black book covered with a homemade covering of black fabric. I opened it and found page after page of Gregorian chant. Real Gregorian chant, Latin, complete with 4 line staff and square notes!
I flipped to the front of the book and read the title: Antiphonarium Romanum. I have never seen one of these before, but its fascinating. Now I have to find a way to use it. I wish I knew how to read real Gregorian Chant. Time to learn, huh?
