In JC there is no lowering a3 into a3, which is a patent error; in the copy there is also no relevant sign before a2. PE is also missing a flat before the latter, which can correspond to the notation of [A], as Chopin often extended the validity of cautionary accidentals onto entire passages or scales of this kind. category imprint: Interpretations within context; Differences between sources issues: Accidentals in different octaves , Omission of current key accidentals , Errors of JC , Inaccuracies in PE |

The natural raising b2 into b2 is featured only in JC (cf. the note on other naturals in this bar). It is certainly a result of using different convention regulating the rules of validity of the accidentals taking into consideration the octave sign. category imprint: Interpretations within context; Differences between sources issues: Accidentals in different octaves |

In the sources there is no before a1. It is related to different range of the octave sign at the beginning of the bar: the second semiquaver triplet is still not embraced by it, which makes that the on the level of a1 (in the notation) appears already before the 6th semiquaver of the bar. category imprint: Source & stylistic information issues: Accidentals in different octaves |
