2 slurs & 2 ties in A & GE

Slur & tie in FE (→EE)
..

In FE (→EE) the lower tie and slur were omitted, certainly by mistake. The error was corrected in GE. Cf. bar 62.

Semibreve in A & GE

Minim in FE (→EE)
..

The rhythmic value of the chord in FE – a minim – is probably erroneous, as in the 2nd half of the bar there is no relevant rest. The error was corrected both in EE (by adding a rest) and GE (by changing the minim to a semibreve). In the main text we give the latter, compliant with the notation of A.

In the further part of the bar Chopin performed corrections in FE, the omission of  at the beginning of the bar seems to be however the engraver's oversight.

..

A has an unnecessary  before c2 before the chord on the 4th beat in the bar, yet it does not have the necessary  raising f1 to f1. In FE the chord was left without any accidental, which was corrected in EE3. The additions were also performed in GE1 (→GE2), in which the accidentals are placed before each note. In GE3 (→GE4) three upper accidentals were removed, therefore, also the necessary  before f1. An unnecessary revision was also performed in EE4, adding a  before c2.

Octave in A

Chord in FE (→GE,EE) 
..

The octave in A is the original version, changed by Chopin in a proofreading of FE (→GE,EE). In FE the correction was inaccurately performed – there are no dots extending the added notes, while the  (cautionary) was placed at the pitch of b2. The rhythmic error was corrected in GE and EE and the  was moved before a2 in GE1, yet removed in EE and subsequent GE,s.
