We add cautionary naturals before B1 and g. The first of them was added already in GE2 (→GE3).

composition: Op. 25 No 11, Etude in A minor

The notation of FE and EE does not include any accidentals in this bar. In GC (→GE1) there is a  before f2 in the 3rd group of semiquavers. In GE2 (→GE3) naturals before e2 and g2 in the 1st group were also added, a  before f2 in the 2nd group, naturals before b1 at the beginning of the 3rd group and before e3 in the 4th group and a  before e1 in the L.H. In the main text we include the  before e2, the 4th semiquaver of the bar.

b. 39

composition: Op. 25 No 11, Etude in A minor

..

There is no accidental before the penultimate semiquaver in GC (→GE1), FE and EE. The missing  returning d3 is undoubtedly an oversight of Chopin, corrected in GE2 (→GE3).

The three-note chord in FE is the original version, which is proved by the visible deletion of the bnote in GC. At the time of introducing this correction, Chopin did not check the notation of the accidentals – the  overlooked on the 2nd beat of the bar was added only in GE.

c1 in GC (→GE), EE1 & EE3

No c1 in FE & EE2

..

The missing c1 note in FE – provided that it is not an error of the engraver – seems to be the original version, cf. bar 47. Lack of traces of its deletion reduces the likelihood of removing this note by Chopin almost to none. The note was removed – under the influence of FE – in EE2, in order to be reintroduced in EE3, this time on the basis of GE
