In AI there is no cautionary  before e1. The sign was most probably added in a proofreading of FE (→GE,EE).

We add a cautionary  before d.

b. 40-42

composition: Op. 10 No 4, Etude in C♯ minor

..

In AI there are a few additional or unnecessarily repeated accidentals ( before a, the 11th note in the L.H. in bar 40 and  before f, the 11th note in bar 41), or totally unjustified ( before d2, the 6th note in bar 40 and before d, the 2nd note in bar 41). In FE (→EE,GE1GE1aGE2GE3) only  before f, the 11th note in bar 41 remained, first removed in GE4 (→GE5).

Our suggestion

..

When interpreted literally, AI has in the last group of semiquavers two notes different than in the published version: the 2nd semiquaver a (without ) and the 4th semiquaver A. According to us, it is a result of overlapping of inaccuracies and corrections, while the text intended by Chopin does not differ from the text of the remaining sources:  

  • at the time of writing a Chopin most probably had a in mind and he even started writing a  before this note. Instead of finishing the sign, he probably decided to change it to g, although the remade (?) note still is more similar to a/a;
  • the last semiquaver is probably written inaccurately, too low.

In the main text we give the version of FE (→GE,EE), completed with the cautionary  before g.
