e1 in bars 61-62 in A1, CK (→CB) & EL

e1 & e1 in CJ, literal reading

e1 & e1 in CJ, contextual interpretation

..

Out of the two versions coming from [A2], we give priority to CK due to its compliance with the unequivocally authentic version of A1. The sharp raising e1 to e1 in b. 61 in CJ could have been placed by mistake, e.g. due to the resemblance of the figures in b. 61-63. On the other hand, one cannot rule out that Chopin wanted to introduce a major variant of the tonic already in b. 61 – cf. the major endings of the Nocturnes in E Minor, WN 23, C Minor, Op. 27 No. 1, F Minor, Op. 48 No. 2 or F Minor, Op. 55 No. 2, consisting of a few or several dozen bars.

In JC, the octave in the L.H. at the beginning of the bar is an erroneous crotchet.

Third d4-f4 not tied in JC

Ties in EF & PE

..

Lack of hold of the 2nd quaver of the bar in JC is most probably a result of the copyist's oversight of the ties.

composition: WN 17, Polonaise in B♭ major

..

It is only in EF that the lower voice on the 4th quaver of the bar is written correctly. In JC it does not appear at all (there are no quavers nor slurs), which is certainly an error due to writing the upper voice with the stems facing upwards. We do not complete this notation, as it is impossible to determine what was exactly missed by the copyist. In PE, lack of the quaver flag next to the f1-bfourth is an obvious mistake.
