b. 240-246

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

..

In A the L.H. part is written in shorthand – only top octave notes and the con 8 - - - indication. GE (→FE,EE) wrote the octaves in full only in bars 240-243; it was only IE that wrote the entire section in full.

b. 240

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

Quavers in A (→GEFE,EE1,IE)

Semiquavers in EE2

..

The EE2 version resulted from a misunderstanding of the original notation – the reviser changed the writing from three-part to two-part.

b. 240

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

..

The deletions visible in A at the beginning of the bar reveal that Chopin initially wrote d1 as the bottom note of the 1st chord, accompanied by F (con 8) as the L.H. octave. Therefore, the  to the next d1 crotchet was most probably meant to cancel the alteration and not to perform the role of a cautionary accidental following d in the preceding bar.
