The changes in the pitch of the 2nd note in particular sources seem to prove Chopin's hesitation; the order of the versions is as follows: b
1 in A, b
1 in GE1, b1 returned in a proofreading of FE (→EE), most probably by Chopin, and b1 written in FED (the version of GE2 is most probably a result of a revision on the basis of A). Chopin's hesitation seems to touch the basic structure of the phrase here: melodically, the beginning of the bar is related to the previous figure, containing a b1, harmonically, it inclines towards the next chord (on the 4th crotchet of bar 41), containing a b1. A melodic solution equal to the version with b1 was used by Chopin against a similar chord in the Mazurka in A minor, Dbop. 42B, bar 52. However, one has to point out that although the authenticity of the version with b1 is unquestionable (A and a proofreading of FE), the first appearance of the version with b1 could be ascribed to a mistake (revision?) of GE while the interpretation of an entry in FED as an added 
is not entirely certain. Due to this reason, in the main text we give b1.
