In GE3 the e-e1 octave is a quaver, as a result of which the bar has only 7 quavers in the part of the L.H. The rhythmic error proves that the quaver flag in this place was printed by mistake. category imprint: Differences between sources issues: Errors in GE , Rhythmic errors |

In AI, in a section starting from bar 17 Chopin marked the staccato dots over the quavers only in the first bar. It certainly means that all subsequent quavers are also supposed to be performed with such articulation, as it was explicitly indicated in FE (→GE,EE). category imprint: Differences between sources |

E in FE (→GE,EE) is probably erroneous – cf. similar figurations in bars 13-14 and 63-66 – hence in the main text we give F written in AI. The error probably consisted in putting a single sharp instead of the double one before the intended E note.

In the version prepared for print, Chopin preferred the more consistent texture and articulation. Cf. the Etude in A minor, No. 2, bars 3-4 and 16. category imprint: Differences between sources; Corrections & alterations |

The fingering of EE – the entire bar 19 and the 1st and 4th groups of semiquavers in bar 20 – is an addition by Fontana. category imprint: Differences between sources issues: EE revisions |
