Slur in GC, FE, EE & GE2 (→GE3)

Shifted slur in GE1

..

Same as in bar 45, in GE1 the slur starts from the beginning of the bar, which is an erroneous interpretation of the too broad slur of GC. In addition, in GE1 the slur is led only to the at the beginning of bar 48, which is a totally unjustified arbitrary decision of the engraver. GE2 (→GE3) re-established the notation of GC, compatible with the remaining sources.

The natural returning e2 is present only in GE and EE3. There is no doubt that we are dealing with Chopin's oversight.

Slur in GC, FE & EE

Slur & '3' in GE1

Only '3' in GE2 (→GE3)

..

In the main text we preserve the additional slur under the quaver triplet, in spite of the fact that it probably indicates only the use of an irregular group. However, Chopin did not mark it clearly, as in GC, FE and EE the '3' digit is absent. In this situation each of these three versions of source notation can be considered as justified (cf. General Editorial Principlesp. 16).

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

..

In GC and FE there is no  raising f to f. This patent oversight of Chopin was corrected in GE. EE also includes the correct text, which is most probably a result of an editorial revision.
