In the main text we suggest quavers, as their authenticity is beyond any doubt. In turn, the crotchets in FE may be a result of the engraver's inattention – the spaces between the c
-B and B-a notes correspond to the previous space c-c (quaver) and not G-d (crotchet), which probably means that the engraver planned the notes, seeing quavers in the base text, however, then he omitted this place while adding the beams. On the other hand, one cannot completely exclude Chopin's proofreading in FE – he may have accepted crotchets during the lessons, as an appropriate correction was not written in any of the three pupil's copies (two of them – FED and FES – bear clear traces of a detailed development of the Etude with Chopin, while in FES the first added fingering concerns exactly these two notes).
