b. 231

composition: Op. 23, Ballade in G minor

In FE (→GE) there is a (cautionary?)  to e3 in the 4th quaver. This unnecessary revision (the accidental is absent in A!) most probably resulted from a misunderstanding or a mistake when correcting another error – in FE one can see here traces of removal of g3 (printed without a , necessary at this pitch). Upon seeing the octave with a  only to the bottom note, the proofreader – perhaps even Chopin – could have instinctively added the other , particularly if he were just adding flats to the L.H. part. Having realised that it is a Terzverschreibung mistake, he marked a change to the pitch of the note, which the engraver implemented by moving the notehead along with the . EE did not include the superfluous accidental.

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.

a2-f3 in A (→FEEE,GE1GE2GE3GE4)

a2-f3 in GE1a

..

The version of GE1a with an a2-f3 sixth resulted from a routine revision based on the idea that diminished or augmented octaves generally come from oversights or mistakes.

4 crotchets in A (→FEEE)

2 crotchets in GE

The version of GE, in which the additional crotchet stems are only at the beginning of both quaver groups, is most probably a double oversight by the engraver.

The  to the top note of the 1st sixth (f3), overlooked by A, was added by FE (→GE,EE). In the main text we add a cautionary  to a2.
