b. 175-176

composition: Op. 12, Variations in B♭ major

..

In FE (→EE) in bars 175-176 in the L.H. the naturals were placed next to the d1 notes. It must be a mistake, since d1 does not require a  in this case; the only note that could require a natural would be b, in each of these bars. In the main text we include a respective correction, introduced by GE, as well as add cautionary flats to b1 at the end of the bars. The change in GE could be attributed to Chopin, as the sound of the FE version (→EE) does not provide any grounds for intervention. However, it is uncertain, as a careful reviser could have noticed the unjustified nature of the naturals to d1, described above, and found an explanation suggested by us, taking into account a few other cases of misplaced accidentals in FE.

In the main text we omit the cautionary  to a2, present in all sources. At this stage of this regular progression, an accidental seems superfluous.
