composition: Op. 10 No 12, Etude in C minor

d3 tied in A

d3 repeated in FE (→GE,EE

..

The sustained d3 note is most probably the original version. Chopin interfered with the text of FE in this bar on a number of occasions (rhythm in the L.H.,   a2), e.g., by adding a slur over both dnotes, hence we can assume that he at least accepted the lack of hold.

composition: Op. 10 No 12, Etude in C minor

f2 in chord in A, GE & EE

g2 in chord in FE

..

The chord in FE – with g2 – may be a result of Chopin's correction introduced in the last phase of proofreading of FE. This would explain the presence of a chord with f2 in GE but not in EE in which either a mistake (?) was committed or a revision was performed. In addition, it cannot be excluded that the revision was implemented both in EE and GE, which seems to be indicated by certain traces suggesting moving the natural before this chord. If this was the case, the version of FE could have been not a result of Chopin's proofreading, yet a simply unnoticed error of the engraver. In the main text we give the undoubtedly authentic text of A, GE and EE. However, we consider the version of FE to be equal, as it could have been an expression of Chopin's final decision.

Demisemiquavers in A

Semiquavers in FE (→GE,EE

..

Double dotted rhythm (with a demisemiquaver) at the end of bars 30 and 32 in A was changed by Chopin during a proofreading of FE (→GE,EE). The change has an undeniable impact on the expressive character of these motifs, however, it also cannot be excluded that it is related to the acceleration of the Etude's tempo, which was also introduced in a proofreading of FE. Cf. bar 27.
In FE bar 32 includes an erroneous rhythm, as the e1-e2 quaver is extended with two dots, despite the fact that the next octave is a semiquaver. It may be a result of an inaccurately performed proofreading.
