The quiet ending of the sonata may have been an afterthought; the manuscript, the only copy of which is available in the Pierpont Morgan Library in New York City, contains a crossed-out ending section which would have ended the work in a loud flourish instead. (Alan Walker, Franz Liszt: The Weimar Years, 1848–1861, Ithaca: Cornell University Press, 1989, page 156. This is in the middle of an extensive analysis of the sonata, pp. 149–157.)
Why hasn't anyone played it? They obviously have the music... although i do like the quiet ending (dare i say a slight anticlimax especially for Liszt?)Tom
The ending as it stands is genius. It1. ties up the themes used throughout the work2. doesn't leave the listener with "wow! what an ending!" Instead it leaves you with an impression of the work overall, which to me is much more effective.
