These are remarkable pieces. Remarkably also they are not discussed by Lockwood, Rosen, Kolodin, Thayer, to mention references at hand. And little discussed it seems on the web.
Listen to (or look at the score of) the second half of #3. Surely it must remind you of a much more familiar piece of music. It took me some weeks before I realized what it reminded me of.
Now turn to the second movement String Quartet, Opus 132, middle section. It's the same passage, except much more development in the quartet. Philemon41 02:39, 25 August 2010 (UTC)
