The notation with E, present in both autographs, was changed – most probably by Chopin – in a proofreading of FE (→GE,EE). According to us, it is however possible that the proofreading concerned an erroneous version – e.g., a sole note head without the ledger line and natural, due to which it looked like an F. It undermines the expression of this change as proving Chopin's preference of the notation with F
instead of E. In the manuscripts the progression of the bass in bars 26-27 is written in a much more natural way: B1-C-E-G-B than in the editions: B1-C-F-G-B.
