b. 82-86

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

..

In the main text we do not include the cautionary  to c2 at the beginning of bar 82 added by GE (→FE,EE,IE). By contrast, we add naturals – necessary and cautionary – to c2 and c3 at the beginning of each half of the bar starting from the 2nd half of bar 82 to the 1st half of bar 86. The majority of them were also added by GE (→FE,EE,IE) – the only overlooked accidentals are: the ones in the 2nd half of bar 82, the 1st half of bar 83 and the accidental to c2 in the 2nd half of bar 83 (in FE the first one was added).

No mark in A

Staccato dot in GE (→FE,EE,IE)

..

The missing staccato mark in A seems to be Chopin's inadvertence, as he overlooked the first chord, separated from the remaining ones by the treble clef and positioned much higher than the following ones. In the main text we include the addition introduced already by GE (→FE,EE,IE).
