composition: Op. 10 No 2, Etude in A minor

..

The cautionary naturals before c1 in the L.H. were added in bars 9 and 13 in one of the last proofreadings of FE (→GE). They are also included in EE, except for the  overlooked in bar 13 in EE2. The manuscripts do not include any signs in these places.

In bars 10 and 14 in one of the last proofreadings of FE (→GE,EE) cautionary naturals before c2 in the last triad in the bar were added. According to us, signs in these places are unjustified.

In the main text we do not consider the cautionary  before the 3rd semiquaver b1. The sign is present in all first editions.

In CLI there are no essential accidentals in the part of the R.H., some of them were also omitted in the base text for FE. In subsequent proofings of FE Chopin, however, added all of them, so final FE (→EE) does not include any errors in this scope. Ap also has a totally correct notation. Lack of the  returning g2 at the end of bar 21 in GE1 probably means that Chopin added it only in the last proofreading of FE. The sign was added in GE2 (→GE3) together with few others, reminding; the majority of the latter were then removed in GE4 (→GE5), while one was added in EE4. We discuss the 2nd half of bar 22 in a separate entry due to the enharmonic difference in the notation of the 10th semiquaver.
