"So gehst du nun, mein Jesu, hin" (#109a)

16' and 8'

"Surrexit Christus hodie" (#108)

This is only the second tune so far with a title in Latin rather than in German.  The previous one was "In dulci jubilo" (#8).  As I noted with that tune, the font is different in both the Register and above the tune itself, so I used a different type font in my video.

16', 8', 4'

"Herr Jesu Christ, mein's" (#107b)

"Herr Jesu Christ, mein's" (#107a)

I think I've noted this before, but it's a particularly relevant comment for this tune:  there are multiple ways in which these alternate notes can be incorporated into the tune.  For this tune, there are nine individual sections of alternate notes, but I almost always try to squeeze together as many as I can, so in the second time through the tune, there are actually five distinct sections of alternate notes I combined.
