b. 92

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

b-g1 in FC (→GE), FE2 & EE

b in FE1

..

The version of FE1 is certainly erroneous. The omitted g1 note was added in FE2. At the same time, mistakes were not prevented – a totally unjustified  was added before the added note, dedicated probably for the bottom note, b – cf. the previous note.

b. 92

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

..

In FC and FE there is no  raising b to b in the 2nd half of the bar. This patent inaccuracy was corrected in GE and most probably in EE, as the defect was present probably in all Stichvorlage manuscripts. The sharp added in FE2 before the 11th semiquaver was probably an attempt to correct this inaccuracy, a doubly failed attempt – the sign was added three semiquavers too late and at a wrong pitch.

f in FE

Same as in analogous bar 8, while proofreading FE, Chopin changed the middle note of the last chord in the L.H. from to f.

No c1 in FE

Lack of the cnote in the 2nd chord is most probably an oversight of the engraver of FE.

d suggested by the editors

The sharp before the bottom note of the chord appears only in the later sources, bearing traces of an intense editorial revision – EE2 (→EE3) and GE2 (→GE3). The revisers could have considered the  in the next bar – written probably due to the simultaneously stroke d1 in the R.H. – to be a signal that there should be a  before the discussed note. In the main text we give the unambiguous version of FC (→GE1), FE and EE1, in which the bass line features a repetition of the sound at the transition between the bars, so characteristic for leading voices in this Etude. In order to avoid doubts, we provide this note with a cautionary natural.
