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.

b. 240-241

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

Slur to f2 in A

Slur to g2 in GE (→FE,EE,IE)

..

Chopin extended the A slur for it to reach the f2 crotchet. Therefore, the version of the editions resulted from a totally unjustified arbitrary decision by the engraver of GE.

b. 240-241

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

Slur e2-f2 in A

No slur in GE (→FE,EE,IE)

..

The missing e2-f2 slur in GE (→FE,EE,IE) is either an oversight or a revision – making one's work easier by omitting a slur on the stave, which requires greater precision.
