Both the Cavatina and the Heilige Dankesang are wonderful conversations with God. But if I have to pick one to accompany me on the way out, I’d pick the latter. It’s deeper and doesn’t have that dip into the Valley of the Shadow of Death that the Cavatina takes in the middle when it goes into C-flat.
The Cavatina is beautiful but it’s definitely not a cheerful send-off !
I just saw your post was numbered 130 !
