b. 178

b. 184

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

b. 186

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

..

In A one can see an erased B note at the beginning of the bar, which means that this L.H. part detail being different in the exposition and the recapitulation – C-c octave in bar 8, but a single B1 note in bar 186 – was not due to distraction. Chopin most probably took into account the different form of the R.H. chord, which could have also been corrected, e.g. by adding one of the bottom notes, d or f.

b. 186

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

..

In A there are no accidentals to the 2nd and 3rd chord in the bar, which is simplification of notation, typical for this manuscript. All 3 omitted flats – d1, d2 and d3 – were added already by GE (→FE,EE,IE).
