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.

Wedges in GC & FE

Dots in GE

No signs in EE

Staccato dots at the beginning of bars 2 and 4 consist the most glaring example of German engraver's misrepresenting wedges in GC – the difference between wedges there and dots in neighbouring bars 1, 3 & 5-7 is very distinct. GE did not use any wedges in the whole Sonata. The lack of signs in EE is most probably an oversight.

GC has a as the last quaver in the L.H. GE corrected this mistake, probably on the basis of comparison with the 1st half of the bar.

In GC bar 2 (the entire bar except for the slur) and bar 5 (part of the L.H.) are written in an abbreviated manner with a /sign. The notation is certainly repeated after [A]. Similar abbreviations appear also in bar 8 and 12-13.

In the previous autographs, Chopin tried varied versions of chords in this bar. Eventually, he used the original version only (with an a-cthird) at the return of this phrase in bar 18. In both previous autographs, it is the absence of a  raising to a that draws attention. According to us, it is not a harmonic variant, yet an inaccuracy of notation, therefore, we consider a literal interpretation (without ) in these sources only a highly unlikely variant.
