b. 252

composition: Op. 21, Concerto in F minor, Mvt III

e1-a1 in A (→GE)

c1-a1 in FE (→EE)

..

The c1-a1 sixth is most probably a mistake of the engraver of FE (→EE). It is difficult to assume that Chopin would like to replace the sequence of three voices of the accompaniment, compliant with all rules, with a parallel shift of chords, sounding worse.

b. 252

composition: Op. 11, Concerto in E minor, Mvt I

..

In FE (→GE1GE2), there is only a  mark in this bar. It may be a trace of a more serious mistake, encompassing half of the line (4 bars) – the mark is missing in bar 249, opening the line. However, taking into account the unquestionable pedalling indications in the subsequent bars, we assume that it was simply a  mark that was overlooked at the beginning of the bar in the discussed place. A corresponding mark was added already in EE and GE3.

b. 252-260

composition: Op. 44, Polonaise in F♯ minor

Staccato dots in GE

No marks in FE (→EE)

..

Chopin could have entered staccato dots in b. 252 and 260 into [A] after Fontana had finished [FC].
