m.s 1 and 26: cresc. for two beats, dim. for two beats.
-corrected notation for m.s 41-44.
-add in allargando in m.s 84 and 85, then a tempo in m.86.
-delete m. 93 completely. It is a useless repeat of the previous bar (m.92).
-corrected notation for m.129 and 130. Add in tied repeat of C-sharp in m.129, so the last chord is four voices. then add in the low G and D in the middle of the long arpeggiated figure, as below.
-interesting fact: note that the only C-naturals in the entire piece are in m.s 174 and 175.
