b. 175

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

Slur from 2nd quaver in A

Slur from first quaver in GE (→FE,EE,IE)

..

The change of the slur's range and place was an arbitrary decision of GE (→FE,EE,IE), in this case unjustified, according to us. See also the note in the next bar.

In the main text we omit the (cautionary?)  before a1 in the 2nd half of the bar, which appears in all sources.

b. 176

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

Slur from 2nd to 5th quaver in A

Slur from 2nd to 4th quaver in GE

Slur from 1st to 4th quaver in FE & EE

No slur in IE

..

The beginning of the GE slur bears traces of corrections in print – one can see two tips of the slur – one suggesting that it should start from the 1st quaver, and the other one indicating the 2nd quaver. According to us, the longer slur, of a regular range (half a bar), was shortened due to the wedge over the 1st quaver. However, the correction was implemented inaccurately, as a result of which in the remaining editions – except IE, in which it was left out – the slur encompasses 4 quavers. In the main text we provide the A slur, running from the 2nd to the 5th quaver.

b. 177

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

Dots in A, possible interpretation 

Wedges in GE (→FE,EE,IE)

..

The staccato marks with which Chopin marked the sequence of thirds in A can be interpreted as dots or wedges. According to us, Chopin wrote dots, which he then turned into wedges, or the other way round – wedges that he tried to replace by dots. Taking into account  dynamics and the clear wedges over the chords marked with  and  in bar 178, we consider dots to be more likely as the final markings. However, the wedges present in the sources can be considered an equally valid variant.

b. 178

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

..

In A there is not a single  raising a (in various octaves) to a. This patent oversight in this structural context was corrected already in GE (→FE,EE,IE).
