"Renew Me, O Eternal Light"

Last month, I watched the Concordia University Wisconsin chapel service from 3 October.  The hymn was "Renew Me, O Eternal Light," and I noticed a small feature in it.  The hymn is sung to the tune "Herr Jesu Christ, mein's."  Here's the second phrase:

In the second verse, the text here is "And cleanse all my impurity."  "Impurity" is sung to notes of all different pitches (F# G E D), giving a sense of the breadth of that "all."  The notes to which the word is sung also span more than two full measures, and this contributes to the sense of breadth, too.

"Herr Jesu Christ, mein's" (TLH #288)

"Lord, Help Us Ever to Retain"

Last year, I noticed a small feature in "Lord, Help Us Ever to Retain."  The hymn is sung to the tune "Herr Jesu Christ, mein's."  Here's the first musical phrase:

The first line is, of course, "Lord, help us ever to retain."  (The direct object is in the next line:  "The Catechism's doctrine plain.")  "Ever" is sung with a melisma (E F# G), and since it's stretched out, there's a sense of duration.

"Herr Jesu Christ, mein's" (TLH #7)

I skipt #6 for a variety of reasons:  I wasn't familiar with it; I couldn't really get a good sense of the tune when I tried playing through it; and it's not strophic, so 1) it didn't seem very hymn-like to me and 2) I think recording it would have been more difficult.

So here's "Herr Jesu Christ, mein's," the tune for #7: "As We Begin Another Week."  I'm not familiar with this hymn, but I am familiar with the tune.
