Issues : Omission of current key accidentals

b. 231

composition: Op. 23, Ballade in G minor

..

In A there are no accidentals to the first L.H. octave, while the  lowering a to a is only just before the 2nd crotchet. Chopin's mistake is evidenced by the  before the bottom note of the last octave in this bar, which would be irrational if the 1st octave were supposed to be A-a (naturally, the mistake is also evidenced by the logic of the chromatic bass sequence). The mistake of A was carefully corrected by FE (→GE,EE) – flats were added to the 1st octave and the consequently superfluous accidental to a in the 2nd crotchet was removed.

b. 236

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

..

In A (→GE1FE) there is no  lowering g2 to g2. The patent inaccuracy was corrected in EE and GE2. EE added also a  before f3, unnecessary according to the rules of validity of accidentals back then.

b. 237

composition: Op. 42, Waltz in A♭ major

..

There are no accidentals before the 2nd chord of the bar in FE0 (→FEG). This patent inaccuracy was corrected in FE1 (partially, as only a  before bwas added) and in GE1 and EE (both necessary naturals). In GE2 (→GE3) the third  before ewas added.

b. 237-239

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

..

In A there is no flat lowering G to G and g to g. This patent inaccuracy was corrected already in GE1 (→FEEE, →GE2).

b. 239

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

..

FE (→GE1GE2) is missing an accidental before the topmost note. A comparison with identical bar 237 proves an unquestionable oversight. A natural was added in EE, GE3 and FEH.
