Issues : Cautionary accidentals

b. 36

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

..

The cautionary  before and a  before d2 are in AI, yet they were not included in A. Naturals before both notes of the octave were added in a proofreading of FE (→EE), most probably in the last phase, as they are absent in GE1. In subsequent GE, the signs were added together with cautionary sharps before d1-d2 in the R.H. The last addition is also present in EE4

The natural before a1 in the R.H. was added by us.

In order to facilitate the interpretation of chromatic progressions, we add a number of cautionary and reminding signs. Only a part of them are in the sources; it also happens that the sources have different signs of this type, which are, according to us, superfluous.

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.
