'Scholarly' articles on 'Un Sospiro'

[nanabush]

Hey all,

Does anyone know of any articles that discuss Liszt's etudes in specific?  I need to take some scholarly stuff and somehow write an essay about why I disagree with it.  I narrowed my topic to something regarding 'showy' music and 'musical' music.  I found in the books I've used so far that a lot of people only want to talk about the virtuosic elements in Liszt's music (and I can see from most forum posts about Liszt that most people are concerned with the technical difficulty in his pieces).  I'm going to try squeezing out an essay about how people dismiss the musical elements in his music and possibly his initial intentions writing it, and that some scholars only really look at that one dimension of his stuff.

The essay is a load of BS, and most people in my class agree.  First of all, the guidelines say we have to discuss a piece from 1800-1850 that we HAVE played, and that we have to disagree with the sources we are using.  It's really tricky because usually the books/articles have info that I agree with 

If anyone knows of any online sources that I could use that would be great; even a book I could grab from amazon or something would be awesome.  I've taken out 5 or 6 books and each only have little bits and pieces about 'Un Sospiro' (the piece I decided to use).  I'm just looking for something more concrete that really goes more in depth than "Un Sospiro is a showman's piece that involves fast notes and crossing of hands".

Thanks a ton, because I'm out of ideas haha
