"Ach, was ist doch unser Leben" (#169)

16' and 8'

Welt, packe dich" (#168)

This is the third tune so far to mix time signatures.  Previously, there were "Brich entzwey, mein armes Herze" (#111) and "O Jesu, du edle Gabe" (#141).

"Sag', was hilft alle Welt" (#167)

I'm assuming that the title is what's sung to the first musical phrase.  If this is the case, the phrase "alle Welt" is sung to notes of all different pitches (F# G A), giving a sense of that breadth, especially since one note is an accidental.

"Lobet den Herren, denn er" (#166)

8' only

"Nun sich der Tag geendet hat" (#165)

The first set of alternate notes makes the tune half a measure longer, so I had to include a blank measure for the other iterations.  It looks kind of odd because this blank measure takes up its own line and seems superfluous at first, but it's the best solution I could think of.

I couldn't get the notes in the eighth measure of the first set of alternate notes to match up with the notes in the corresponding measures of the other iterations as well as I would have liked.  Because there are so many eighth notes taking the place of quarter notes, there just wasn't enough space.

8' only

"Danket dem Herren, denn er ist" (#164)

The title seems to come from the Psalms.  Psalm 106:1, 107:1, and 136:1 are all some variation of "Danket dem Herrn, denn er ist freundlich und seine Güte währet ewiglich" ("Give thanks to the LORD, for he is good, for his steadfast love endures forever").

8' and 4'

"Nun ruhen alle Wälder" (#163)

This is similar to the hymn tune "O Welt, ich muss dich lassen."

16' and 8'

"Werde munter, mein Gemüte" (#162)
