This is the song that Sulzer sight-read that evening. It requires a really good low C# at the end. I dug up a video with both German and English lyrics, and with Fischer-Dieskau singing.
At 2:00 there is a melody that lived on in another piece by Schubert. Years after writing "The Wanderer", he was approached by a wealthy piano student of Hummel for whom he wrote the "Wanderer Fantasy". Normally Schubert avoided showpieces with piano pyrotechnics, but the money was good, and Schubert delivered. (Boy, did he deliver!) He took that theme and turned it into a four movement sonata with the movements all joined together without interruption.
In the first movement, he lays it out in sonatina format (no development) in C Major.
In the slow movement he goes to the original key of the song, C# minor, and builds a theme and variations movement. At one point he writes entire pages of 128th notes. The pace is very slow in split-C, so the notes can be heard discreetly.
The third movement switches abruptly to A-flat for a scherzo based on the Wanderer theme.
He saves the best for last when he returns to C Major and works up the theme as a fugue for the finale. It's a great finish to a great piece.
I need to brush up on my SCALES! LOL!
Thanks, that was a real treasure.
