The version of FE (→GE1,EE) with a d1-b
1 sixth is most probably erroneous, which is indicated by a comparison with analogous bar 287, in which there is a fifth. It is also the change to d1-b1 written in FEJ that supports the thesis that the majority of the sources contain a mistake. At the same time, it was rather an e1-b1 fifth that corresponded to Chopin's original idea, since d1 in the second chord required the use of a 
. According to us, an additional argument in favour of a fifth is a characteristic juxtaposition of the c1-a1 sixth with the e1-b1 fifth (bars 117, 120, 125, 141), which appears a few times in this theme – wherever the melody features a1 and b1 against the A major and E7 chords. Taking into account the above, in the main text we give an e1-b1 fifth. That version was introduced also in GE2.
