b. 373

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

No slur in sources

Slur suggested by the editors

..

As in bar 190, in the main text we suggest adding a slur after analogous bar 7, which is marked more accurately.

b. 374

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

No mark in A

Wedge in GE (→FE,EE,IE)

..

In the main text we do not include the wedge added in the editions over the 2nd crotchet. It is true that the mark is present in A in bar 8, but the set of markings in that bar is clearly different than the one here or in bar 191.

b. 374

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

No sign in sources

Arpeggio sign suggested by the editors

..

As was the case with the preceding chord, Chopin's oversight seems much more likely than an intentional omission of the arpeggio.

b. 374

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

..

In EE1 the  raising b to b was overlooked. The manifest error was left uncorrected in EE2.

b. 376-378

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

Slurs from 2nd quaver in A

Slurs from 1st quaver in GE (→FE,EE,IE)

..

In bar 376 and 378 in the main text we keep the notation of the A slurs, as the comparison with analogous bar 10, 12 and 193 shows that Chopin – although he did not mark it here – most probably envisioned the initial octave to be performed staccato. However, one can understand the engraver of GE, who considered the A notation to be another case of inaccurate slurs (particularly the slur in bar 378, the ending of which is certainly inaccurate).
