I have no idea what this is

Hi MG,

"I'm particularly struck by moments such as
that in measures 39, 40 with the tension created by the dissonance and
its unwinding in the measures immediately following".

Good heavens! Somebody has actually made sense of this piece! When I play it back around here, I get looks from everybody like they are all ready to call the guys with the straightjackets. Thank you!

Cheers... Fred
