I don't currently have any notes about Epiphany hymns to write about, so I'm going to continue with Christmas hymns.
In October 2018, I recorded the tune "Der Tag, der ist," used with TLH #78 "Hail the Day So Rich in Cheer." I noticed a small connection between the text and the second phrase:
In the second verse, the text here calls Jesus the "King of all creation." "Creation" is sung with a melisma (F# G A G), musically giving a sense of the breadth of that "all."
