b. 16

b1 in A

g1 in FE (→GE,EE)

..

Both versions may be considered as justified here, both from the musical and source point of view. In the version of A Chopin avoids tripling the leading tone g1. The version of FE (→GE,EE) may be considered as accepted by Chopin, who introduced changes, among others, exactly in this bar (pedalling) while proofreading FE. The accompaniment's figure in this version has a similar scheme to the figures in the preceding bar and is identical to the figure used in bar 8. In the main text we adopt the version of the base source, i.e. FE.

 &  in A

No markings in FE (→GE,EE)

..

Omission of  and  written in A may be an error of the engraver of FE (→GE,EE) or a result of Chopin's proofreading. In the main text we give the version of the editions, in which the level of dynamics of the ending of the phrase is not specified. It is worth observing that locally the lack of these indications only adds shade to the dynamic flow of this fragment, as cresc. in bars 14-15 and an accent in the middle of bar 16 were retained.

No sign in A (→FE)

 in GE & EE

In this context, the missing  mark is undoubtedly a result of Chopin's inattention, who added pedalling in a proofreading of FE, or – which is more plausible – of the engraver implementing this proofreading. The mark was added both in GE and EE.
