Op. 25 No 1, Etude in A♭ major
Both versions are certainly authentic, yet their chronology raises some doubts. The version with e3 was probably created earlier, as in AI it is already written with ink. Therefore, the octave in A is to be considered as one of these Chopin improvements that appeared in A with no traces of changing the version of AI (cf., e.g., bars 1, 7, 8). However, if – which seems to be likely – the base texts for FE and EE were copies of A, one should assume that Chopin added an e
3 in them, thus returning to the original concept. However, not being entirely certain in this respect, in the main text we preserve the lighter version of A (→GE).
