b. 121

composition: (Op. 4), Sonata in C minor, Mvt I

..

In A there is no  to the top note of the 2nd R.H. quaver (f3). The patent inaccuracy was corrected in GE (→FE,EE,IE).
In the main text we omit the unnecessarily repeated  to e3 in the last quaver in the bar. The change was also introduced by IE.

b. 121-122

composition: (Op. 4), Sonata in C minor, Mvt I

..

In A the bottom notes in the majority of the octaves are devoid of naturals (there is only one natural, to B at the beginning of bar 122). In GE (→IE) only the naturals to e and E were added. In EE1 the L.H. part in bar 122 does not contain a single accidental, which was corrected in EE2 by adding two naturals before the 1st, 2nd and 4th octave. The fully correct text is to be found only in FE.

Continuous slur in A

2 slurs in GE (→FE,IE)

1 slur in EE

..

In A the slur in bar 120, which ends a line, reaches the bar line, yet it is very close to the last quaver, hence it can be interpreted both as a slur ending in this bar and as a slur that should be continued. The beginning of the slur in bar 121 is misleading – the main part of the slur starts over the 1st quaver, yet Chopin started writing it much earlier, which is poorly visible due to ink stoppage. When considering the slur as a whole, it undoubtedly indicates that it should be continued from the preceding bar. Therefore, in the main text we provide a continuous slur, which is more natural in terms of music. The version of the editions resulted from an inaccurate interpretation of the slurs by the engraver of GE, while in the case of EE also from an oversight by the engraver of EE.
