The second phrase of the tune ("Coronation") descends:
and in the first and seventh verses, this musically represents the lines "Let angels prostrate fall" and "We at His feet may fall!"
I also noticed some connections between the text and a group of eighth notes in the third and fifth phrases. (The last two lines of each verse are sung twice, but the melody is different, so while there are only four distinct lines in the text, there are six phrases in the music.) In the first verse, the line here is "Bring forth the royal diadem," and in the seventh verse, it's "We'll join the everlasting song." "Diadem" and "everlasting" are sung to these four eighth notes (plus some quarter notes on either side):
Third phrase:
Fifth phrase:
These eighth notes have two different extra-musical functions. In the first verse, they mirror the "diadem." The melisma here ("diadem"'s being sung to five syllables rather than just three) is a musical ornamentation in the same way that a diadem is a decoration. In the seventh verse, singing "everlasting" to more syllables than normal (six rather than four) gives a sense of that temporal continuation.
