Lack of natural next to d1 is an obvious Chopin's error. The version with a (without the flat raising to a) is musically possible, yet Chopin's annotation in FES indicates rather a double error of the composer in A and FE. category imprint: Interpretations within context; Differences between sources issues: Annotations in teaching copies , EE revisions , GE revisions , Omission of current key accidentals , Errors of A , Annotations in FES |

Before the last small note in A, FE and EE there is no natural raising b1 into b1. This obvious oversight was corrected in GE. category imprint: Differences between sources |

In A (→GE1) and FE there is no natural raising d1 into d1. In this context, it is undoubtedly Chopin's oversight, one of the most common. The natural was added in all 3 pupils' copies. In GE2 a flat was added in front of the upper note, which was corrected in GE3 (→GE4). EE has doubly erroneous version, caused probably by Chopin's manner of writing seconds vertically and not diagonally. category imprint: Interpretations within context; Differences between sources issues: Annotations in teaching copies , Errors in EE , GE revisions , Omission of current key accidentals |

A and FE are lacking the e1 natural on the 3rd crotchet. The natural appears in all remaining sources. The error was corrected by Chopin in the pupils' copies. category imprint: Differences between sources |
