Fourths in A

In the proofreading of FE1, Chopin added b1 and a1 respectively to the last two quavers. With the sustention of d2 it constitutes an undobted improvement of this end of phrase.

b. 20

Staccato dot in A

No dot in FE (→GEEE)

..

FE (→GE,EE) overlooked the staccato dot for the D1-D octave in the L.H. The engraver's oversight was certainly caused by the unclear notation of A, in which Chopin introduced some of the dots in a very delicate manner and at the same time not directly under the note (moved to the left or to the right) and additionally merging with the pedalling signs.

[] suggested by the editors

..

The absence of the  asterisk in this place is rather to be considered to be an inaccuracy of notation, hence in the main text we suggest to add the sign. A similar revision was performed already in EE and GE2 (→GE3GE4GE5).

In GE2 in bar 21 the  indication was arbitrarily changed to , whereas in GE3 (→GE4GE5) erroneously to  (similarly as in bar 19).
