b. 2-4

composition: Op. 25 No 5, Etude in E minor

..

The subsequent GE added cautionary naturals in these bars – already in GE1 before the second g2 in bar 3, in GE2 before in bar 4, in GE3 before a1 in bar 2. The sign in bar 3 was added in EE3 too. According to us, all signs are justified and we adopt them to the main text.

We add cautionary naturals before g1 in bar 5 and before the first c2 in bar 6. The signs were added already in GE3, together with the naturals before a2 and c2 at the beginning of bar 8.

composition: Op. 25 No 5, Etude in E minor

Before g2 at the end of bars 8 and 11, GE added cautionary naturals. It is most probably an editorial revision. The addition was introduced – probably under the influence of GE – also in EE3.

The version of FE (a chord with f) is a result of Chopin proofreading from the version of the remaining sources (a chord with a). The traces of performing changes in print are present in FE both in this bar and in analogous bar 105. In a similar place in bar 36, all sources feature a chord with f

in FE & EE2 (→EE3)

Both versions of the 1st note of this bar are undoubtedly authentic, yet determining which one could have been considered final by Chopin faces major difficulties. The version with f seems to be later, as in FC one can see a correction in which the composer most probably deleted and added f, whereas a similar correction was most probably also in the base text to EE. However, while proofreading FE later, Chopin did not introduce this change, in spite of the fact that he corrected the last chord in bar 8, positioned just next to it (1 cm). Therefore, in the main text we follow the version of the base source, i.e. FE.
