The second post on notes 29 & 30:
n30: ^5-^6-(^5)^7-^8: Winterreise, no. 2, “Die Wetterfahne.” No comment in the note. The piano opens a large space of a compound fifth in the introduction ("geschwind, unruhig"), but the voice constrains its opening phrase by sequence, so that a line rises from ^3 to ^5 (beamed).
The sudden turn to the parallel major in the verse cadence is sarcastic, as his former lover "ist eine reiche Braut" ["a rich bride'].
The final cadence of the song amps up the cry of despair with a strong sequence but odd chord progression -- first system below -- then drops back into the "reiche Braut" figure to end. In the 1987 article I enclosed the second ^5 in parentheses, and have repeated that below, but nowadays I am more inclined to accept the "primitive rising line" and so would probably read the ending as ^5 (^#6 ^5) ^#7 ^8.
