The cautionary flats before a1 in b. 12 and 20 were added in the first phase of proofreading of FE (→EE). It is unclear whether Chopin was responsible for the entire process of that phase of proofreading. category imprint: Differences between sources issues: Cautionary accidentals , FE revisions |

In the main text we add cautionary flats before e2 and e1. The latter was already added in the proofreading of FE (→EE), although one cannot be certain whether such additions come from Chopin. category imprint: Differences between sources; Corrections & alterations issues: Cautionary accidentals , FE revisions |

Due to the following reasons, in the main text we include the pedalling of GE in a variant form only:

In b. 20 and 25, GE included upper voice rests on the 1st beat of the bar. Formally necessary, such rests often do not provide any useful piece of information in piano music notation, hence they were not used by Chopin. Therefore, it is highly likely that their presence in GE is a result of a revision. category imprint: Differences between sources issues: GE revisions |

In the main text we adopt the notation of the principal source, i.e. GE, undoubtedly repeated after [A2]. It is unclear what Chopin's motivation was when he changed the mark to a double grace note in this particular place, hence both manners of notation are considered equal. The same applies to b. 54 and 98. category imprint: Differences between sources; Corrections & alterations |
