b. 27

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.

Long accent in A

 in FE (→GE,EE

Our suggestion

..

According to us, the mark in A under the last chord in the R.H. is a long accent. In the editions it was reproduced as  hairpins, which can be considered as an alternative interpretation of the notation of A. In the main text we suggest to move the accent over the chord, in accordance with the corrected version of the rhythm, in which the melodic d3 note is repeated.

In A (→FEEE) there is no natural raising the 14th semiquaver in the bar (from b to b). The inaccuracy was corrected in GE.
