I wrote about "All Glory Be to God on High" last month, but when I lookt over the hymn again, I found an-other small feature to write about.
In the second verse, there are the lines "O Father, for Your rule is true / And just and changes never." The second of those lines is sung to this phrase from the tune "Allein Gott in der Höh'":
"Changes" is sung with a melisma (Bb A G), so while it's negated, there's a musical sense of its meaning.
