"Father Most Holy"

While working on the post about the Biblical sources of "Father Most Holy" last year, I noticed some small features in the hymn.  It's sung to the tune "Christe sanctorum"; here's the last musical phrase:

The end of the second verse calls the Trinity "Hope of all living."  "Living" is sung with a melisma (F# E D), musically giving a sense of the entirety of that "all."

The fourth verse ends with the lines "Glory we offer, praise Thee and adore Thee, / Now and forever."  Here, "forever" is sung with a melisma (G F# E D), musically giving a sense of duration.

The whole note in this phrase is the longest note value in the entire tune, and it also provides a sense of the breadth of "all living" and the duration of "forever."
