Double dotted rhythm (with a demisemiquaver) at the end of bars 30 and 32 in A was changed by Chopin during a proofreading of FE (→GE,EE). The change has an undeniable impact on the expressive character of these motifs, however, it also cannot be excluded that it is related to the acceleration of the Etude's tempo, which was also introduced in a proofreading of FE. Cf. bar 27.
In FE bar 32 includes an erroneous rhythm, as the e1-e2 quaver is extended with two dots, despite the fact that the next octave is a semiquaver. It may be a result of an inaccurately performed proofreading.
