This is about a child trapped in quicksand with a music box in its hand. And apparently it matters that "no angel climbs down, only rain weeping on the grave, with a melody in the Wind/ Pneuma". We hear this "on a Mortal Sunday as God's husbandry and the little heart of the child is saved". "My heart beats no more, and on Earth the child sings". ?
"Hoppe Hoppe" is from a nursery rhyme with the infant being bounced…
Ein kleiner mensch stirbt nur zum schein
Wollte ganz alleine sein
Das kleine herz stand still fr stunden
So hat man es fr tot befunden
