In FED there is an added before a2 in the chord at the beginning of the bar. We also believe that it is advisable in this place, thus we give it in the main text. category imprint: Differences between sources issues: Annotations in teaching copies , Annotations in FED , Cautionary accidentals |

The additional b1 note in GE is most probably a mistake. In A Chopin wrote analogous bar 35 too, also without this note. category imprint: Differences between sources issues: Errors in GE |

The origin of the additional e note present in the 1st chord in the bar in FE (→GE,EE) is unclear. Chopin could have added it at the time of proofreading FE, yet it seems more plausible that it was printed by mistake instead of g (Terzverschreibung) or B (the second possibility is indicated by the length of the arpeggio wave). Then the correct note was added, yet the erroneous one was not deleted, which is a characteristic error of engravers (the then printing technique made adding a note much easier than deleting it). Similar mistakes were often committed in other Chopin's works, e.g., in the Scherzo in B minor, Op. 20, bars 135 and 292, the Ballade in G minor, Op. 23, bar 171 and the Polonaise in A major, Op. 40 No. 1, bar 93. Cf. the remark concerning the Etude in G major, No. 5, bar 59. category imprint: Differences between sources issues: Errors in FE , Errors resulting from corrections , Terzverschreibung error , Authentic corrections of FE |

..
In A there are visible traces of a change of the bottom note in the 3rd chord in bars 5-6 (as well as in bars 13-14, which are marked in an abbreviated form in A as a repetition of bars 5-6). Originally, all the places featured c2, hence Chopin proceeded from the strictly analogous version to bars 1-2. Cf. bars 37-38. category imprint: Corrections & alterations; Source & stylistic information issues: Corrections in A |

composition: Op. 10 No 11, Etude in E♭ major
..
The change of the inner note in the 4th chord in bar 7 from e1 written in A to f1 featured in FE (→GE,EE) is most probably a result of Chopin's correction. The composer could have striven for a smoother combination of this chord with the next one, without a progression of parallel fifths. According to us, the correction intentionally concerns also two repetitions of this place, in bars 15 and 39 (Chopin omitted one of a few similar places at the time of proofreading on a number of occasions, e.g., in the Etude in G major, No. 5, bar 4). category imprint: Interpretations within context; Differences between sources issues: Authentic corrections of FE , Omitted correction of an analogous place |
