b. 188-189

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

No tie (slur?) in sources

Tie (slur?) suggested by the editors

..

The analogous L.H. sequences in bars 187-188 and 188-189 are most probably supposed to be performed identically. Due to this reason, in the main text we suggest adding a slur (or a tie?) to c1, as marked by Chopin in bars 5-6.

b. 188-189

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

3 wedges in A (→GEEE,IE)

1 wedge in FE

..

The absence of the first 2 wedges in FE is probably due to the engraver's inattention.

b. 190

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

f2f1f in A

f2f1f in GE (→FE,EE,IE)

f2 (), f1f suggested by the editors

..

As in bar 7, in the 2nd half of the bar A does not include any accidentals, while the sharps raising all f notes (in various octaves) to f present in GE (→FE,EE,IE) were arbitrarily added during the revision of GE. In the main text we provide the A version, adding only a cautionary  to the first of the discussed notes (f2).

No slur in sources

Slur suggested by the editors

..

In the main text we suggest adding a slur after analogous bar 7, marked more accurately. Similarly, in bar 373.

b. 191

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

No mark in sources

Wedge suggested by the editors

..

In the main text we suggest a wedge after analogous bar 374, which is provided with a similar set of indications (contrary to bar 8, which contains many more markings).
