Favorite Shape-Note songs: Idumea, Babylon is Fallen, David's Lamentation, Samanthra, Greenfields, Evening Shade, Watchman, Parting Hand. I first learned the seven-shape system from the Christian Harmony Book with Richard Moss at the Berea Christmas Country Dance School. It makes the most sense to me, with a different shape for each of the notes; do, re, mi, fa, so, etc. The four-shape system is much more widely used here in Texas, but it doesn't make sense to me. Luckily the songs are the same, for the most part.
