b. 218

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

b2-g3 in A (→GEFE,IE)

b2-f3 in EE

..

The EE version of the last quaver must be wrong – the position of the notehead of this f3 (too high) proves that the engraver forgot to write a ledger line for this note.

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

No marks in A

2 wedges in GE (→FE,EE,IE)

..

Performing the crotchets in this bar staccato, as in the preceding bars, seems natural, hence highly likely. However, Chopin did not mark it, as one can imagine a change to the kind of articulation due to the possible continuation of crescendo; in the main text we leave this issue to the discretion of the performer.

b. 218

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

Short accents in GE (→EE,IE)

Long accents in FE

..

It is difficult to find a justification for the change of font and position of these 4 accents in FE – in GE they are identical to the ones in bar 217 and 221-222.
