Issues : Errors of A

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.

In A (→FEEE) there is no  restoring b2 on the penultimate quaver. A comparison with similar phrases an octave higher and lower proves that it was an oversight by Chopin. The accidental was added by GE.
