Same as in bar 18, in GC (→GE1) and FE there is no  raising g2 to g2.

b. 28

Similarly as in bar 20, Chopin's mistake in [A] caused that the correct notation of the trill appeared in the editions – despite the proofreading of FE3 – only in GE2 and EE2. The mistake was corrected in all pupil's copies.

B with slur in GC (→GE)

d in FE3 (→FE4,FE5)

It seems to be highly unlikely that the change introduced in the proofreading of FE3 (→FE4,FE5) would correspond to Chopin's intentions. The present in the remaining sources B-A step of the enforced with octaves bass constitutes here the essence of the transition, introducing the middle section in the D major key. The importance of this step is emphasised by the slur in GC. It is likely that at the time of this correction a kind of misunderstanding arose (cf. the commentary to bar 20 and analog.). In two pupil's copies – one with B (FESch) and one with d (FED) – there are no corrections, yet in FES Chopin changed d to B. See also bar 84.

Each of the source versions could have been intended by Chopin, yet only the authenticity of the version with mordent is unquestionable. On the other hand, the notation with the use of grace notes, present certainly in analogous bar 52, is clearly later. Taking the above into account, in the main text we suggest an ornament in the form of grace notes.
