"Unlike Beethoven’s sonatas, but like his own song cycles, Schubert’s piano sonatas were not of a nature to inspire the need for public performance for a long time. Sviatoslav Richter’s comprehension of this special intimate nature can explain his interpretation of some of the late sonatas. his very slow tempo in the first movement of the last sonata in B-flat Major (marked only Molto moderato) excited the derision of Alfred Brendel. As I remember, Richter takes almost half an hour for this movement alone, with three more still to go. Brendel was right in thinking the tempo incorrect or inauthentic, but he also appeared not to feel that the intimacy of the work was also essential to its authenticity, and contented himself with a large- scale rendition. The movement is indeed of grand dimensions, but the paradox of schubert’s style here is the astonishing quantity of dynamic indications of pianissimo and even ppp, broken most memorably just before the repeat of the exposition by a single fierce and unexpectedly brutal playing as loudly as possible of the trill of the principal motif, heard so far only very softly (a repeat that Brendel refused to perform, perhaps because the unprepared violence is awkward in a large hall, although paradoxically more convincing in an intimate setting). Richter was an extraordinarily intelligent musician: whenever there was a significant detail in the score, it was always signaled by a reaction in his interpretation, not always, perhaps, the reaction that one would have liked, but no matter."
