In FE, the visible traces of corrections performed in print prove that this bar underwent a serious, probably multiple-stage, proofreading. However, we did not manage to decipher the original text, although some of the removed elements are quite clearly visible. The erroneous version of GE – 
– probably corresponds to the penultimate stage of the changes introduced in FE. The final text is unquestionable – the version of FE is compliant with the chord in the orchestral part and must correspond to Chopin's intention, since it was proofread a few times. We consider the version resulting from the removal of the erroneous 
from before the 1st chord, generally compliant with the text of the remaining sources, to be the edited text of GE1 (→GE2). GE3 introduced the same change; it also removed the superfluous 
from before b1. None of GE contain cautionary naturals before a and a1, which are present in FE (→EE).
