b. 94

composition: Op. 44, Polonaise in F♯ minor

E-e in GE

C-c in FE (→EE)

..

In the main text we give the enhanced version Chopin introduced while proofreading FE (→EE). A similar change was entered into b. 96; in both places one can see traces of changes being performed in print. The same applies to analogous b. 118 and 120.
In FE there are no accidentals to the changed notes, which, when interpreted literally, would result in C-c. The patent oversight was corrected in EE1 by adding a  to the bottom note. In the main text we add 2 naturals in accordance with the manner in which Chopin wrote down this section – cf., e.g. the naturals to the F-f quavers in b. 88, 90, 92. Two naturals are also in EE2 (→EE3).

b. 95-96

composition: Op. 44, Polonaise in F♯ minor

..

In these bars Chopin overlooked the naturals lowering g(1) to g(1). It is proven by the absence of those accidentals in FE (→EE) and by the fact that they were added in print in GE, which is indicated by the gaps between the notes. The authenticity of the additions to GE is not confirmed, yet Chopin's mistake is evidenced by analogous b. 119-120, in which accidentals are present in all sources.
