this seems to be in a sort of ABACADA or some such rondo form. i liked how it 'evolved.'
i just listened to uchida's interpretation and some of it is quite similar to yours at the beginning. i'd like to hear a few more - because to me it sounds 'choppy.' i can't explain this very well. but, there was some schubert interpreter that i remember hearing recordings of years ago. perhaps listening to some of your favorite artists will give you some other ideas for handling the transitions just a tiny bit different? if you want? maybe you are happy. all that really matters is that you feel you interpreted schubert as you see him. he always seemed to me to be that spectacled library man taking in everything (sights and sounds) around him as he took walks. second only to the beethoven nature walks. and, as he walked, he sensed a drama going on. the drama of the constant push and pull in life. you can almost see a spiritual battle. of course, with the erkling, this is obvious. but, i mean - even here. the impetuous 'da da dum, da da dum' is attempting to tempt somebody. then, the feminine (or whatever) response is given. you have to have a bit of crazy in you.
