In the main text we give the version with d1, present in the majority of the sources, including in A. The version of FE could be a result of Chopin's proofreading, however, one cannot exclude a mistake of the engraver or copyist.

The fourth semiquaver in the R.H. in A is written too low, so it resembles rather a d1 than an e1. This is how it was interpreted in GE1 (→GE1a). The erroneous d1 is also present in CDP and EE, while the visible traces in FE prove that initially also this edition included d1. It constitutes a strong argument for – indirect or direct – provenience of all these sources from A. Apart from AI and FE, the correct text is also to be found in GE2 (→GE3).

The version of the 1st half of the bar, written in AI, A (→CDP,GE1) and EE is undoubtedly earlier. Chopin introduced the final version in proofreadings of FE and GE1a (→GE2), probably in order to avoid parallel octaves at the transition from the previous bar (cf. the commentary to the Etude in A minor, Op. 25 No. 4, bar 60). GE3 arbitrarily reinstates the version of A.

The third group of semiquavers in the L.H. was changed by Chopin twice (cf. the note concerning the R.H.), hence it appears in the sources in three various versions. In the main text we give the latest of them, introduced in FE and in a proofreading of GE1a (→GE2GE3).

The version of FE may be a result of Chopin's correction – in the manuscript base text or in the very FE. One cannot also exclude a kind of misunderstanding at the time of interpreting the manuscript. Due to these issues, in the main text we give the undoubtedly authentic version of the other sources.
