In FED there is an added  before a2 in the chord at the beginning of the bar. We also believe that it is advisable in this place, thus we give it in the main text.

In bar 17 we add cautionary naturals before f1 and f2. In bar 19, in a similar situation, the signs are already included in A.

In bar 17 in A there is a visible trace after the change of the lower note of the 3rd chord in the R.H. from g1 to f1. Chopin introduced similar changes also in bars 19 and 21. Cf. bar 22.

The text does not raise any doubts here, yet the notation of accidentals differs in particular sources and it is not always precise. In FE the  before the 1st chord in the L.H. was initially placed at the pitch of c1 and it was probably at this stage that the copy constituted the base text for GE, in which the accidental was moved to the correct place (before g). In FE (→EE) the  before c1 was eventually changed to a , yet the necessary  before g was added only in EE. In GE2 (→GE3→GE4) a  was added before c1, as well as before c2; the latter was also introduced in EE4. In A there is no flat before g2 in the 5th chord, which was already added in FE (→GE,EE).
