I am looking at the first section of Sor Op. 44 No. 15, and I'm having trouble placing my finger on what should be the underlying chord in the third to last measure leading up to the repeat.
Here's what I have so far, measure by measure:
So, what makes sense to fill in that question mark?
In the scale run there's a g-sharp so it seems a little like the key could be temporarily changed to A major.
An E-major or E7 chord doesn't quite blend with the A at the top of the run though...
