b. 45

composition: Op. 10 No 3, Etude in E major

Both autographs lack some of the necessary naturals in this bar, although these which are included allow for a clear interpretation of the text:

  • in AI there is no sign before c2 in the 3rd chord in the R.H., while the  before c is unnecessarily repeated on the 6th semiquaver in the bar (due to the brief notation of the octave, the sign concerns also the bottom C); 
  • in A there is no  before the bottom C at the 2nd semiquaver, while the only sign in the part of the R.H. is a  before c2 in the last chord.

The necessary signs were added in FE (→GE,EE), while in GE4 (→GE5), the unnecessary  at the end of the bar was removed.

Lack of the  sign in FE (→GE,EE) seems to be one of numerous mistakes of the engraver of FE of this type. However, possibilities of a proofreading intervention of Chopin cannot be totally excluded here – cf. the adjacent note.

The notation of accidentals is not accurate in the autographs, particularly in AI. Typical for Chopin omissions of signs written simultaneously or slightly earlier next to proper notes in another octave, as well as oversights of cancellations of previous alterations, do not, however, lead to any misunderstandings, as far as the interpretation of the intended text is concerned. In all sources there are also signs of cautionary or reminding nature. In the main text we include these which Chopin wrote in A.
