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 on the knees, like a horseback rider.
