b. 83

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

..

Initially, c-g-a-cwas the first chord in the R.H. in A, which was carefully changed by Chopin to c-f-a-c1, repeated in the first editions.

() suggested by the editors

..

It is uncertain why  written in A was not included in FE (→GE,EE). Lack of the traces of a possible deletion of the mark allows to assume its omission by the engraver, e.g., in relation to lack of space between the staves. Due to this fact, in the main text we suggest a variant solution. At the same time, we move the indication to the beginning of the bar, as the way it is written in A suggests that it concerns the entire chordal ending of the Etude. This conclusion, as well as the very need for a dynamic indication in this place, is confirmed by Chopin's entry in FED

Dots & wedges in A

Dots in FE (→GE)

No marks in EE

..

The difference between dots and wedges in A is very clear, yet it was not included in FE (→GE). Taking into account numerous inaccuracies of the notation of staccato marks in FE, we give preference to the detailed indications of A. In EE all dots were omitted.

b. 83-84

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

..

In A the bottom notes of the octaves in bar 84 are written in an abbreviated form with the use of 8. In FE (→GE1GE2, →EE), undoubtedly due to lack of space, the notation was also extended to bar 83. The notation of A was returned in GE3 (→GE4), which, however, was certainly an independent decision of the reviser.

Slur in A

No slur in FE (→GE,EE

..

Same as in the case of , one can have serious doubts whether omission of the slur over the pair of chords in FE (→GE,EE) was intended by Chopin. Therefore, in the main text we suggest to consider this mark.
