I've reviewed some aspects of Piano Sonata No. 31 that caught my attention. The key points are adjustments to the legato passages and dynamics. However, the biggest challenge is whether the third movement is well expressed. It's all about the interactions between the two Klagender Gesang sections and the fugue. But for me, these things never feel truly 'finished.' I'll let it sit for a while and revisit it again later.
