At the Dwarsloop church I saw a few hymnals lying about, so I opened one. I don't know what language they sang in, though one would assume it is the Tsongan language, since that's the group we were with.
What especially intrigued me was the way music is noted. It took me a little while to figure this out, but I eventually did. I wonder if you can figure it out, too? If you do, add a comment, below.
You know the hymn, "The Cleansing Wave"—an old gospel hymn that we used to sing at baptisms. Here's the first phrase of it.
Hint: The Sound of Music.
