In both autographs the moment of starting the slur is not entirely clear. In the case of AI we can rely only on a photography, hence, there is no certainty whether all details of the original are clearly visible on it (it is possible that, e.g., the initial fragment of the slur was written with such a delicate line that it is invisible on the photography). According to us, in both cases there is no doubt that, as far as the shape of the slur is concerned, Chopin wanted to begin the slur in the most natural way possible in this context, i.e. from the beginning of the phrase, hence from the beginning of bar 1 in AI and from the upbeat in A (this is how it was interpreted in GE). Such an interpretation of A is confirmed by the slurs of FE and EE, based on other manuscripts. category imprint: Graphic ambiguousness; Differences between sources issues: Inaccurate slurs in A , Pointing slurs |

In the main text we give the title and dedication in accordance with the title page of the entire opus in A (we develop the Mme and Csse abbreviations used in A) and FE. In A (→GE) and FE, the particular etudes are provided with an additional title, Etude, with a corresponding ordinal number, which we represent through the number preceding the score. In EE, the numbering includes 12 Etudes, Op. 10, hence this etude is No. 13. category imprint: Differences between sources issues: EE revisions , Dedications , GE revisions , Deletions in A |

Chopin added the tempo indication, including the metronome tempo, only at the stage of preparing the Etude for publication – in #AW they are absent. In A one can see that the metronome tempo was added (in pencil) to the already finished manuscript. In CDP, the entire first part of the manuscript (to bar 19) is devoid of any performance markings, which almost certainly does not reflect the state of the copied manuscript (probably autograph). Due to this fact, we do not include this source in the notes discussing the performance indications. category imprint: Differences between sources issues: Errors of CDP |
