b. 197-198

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

Slur in A

No slur in GE (→FE,EE,IE)

..

The A slur could easily be taken for an insignificant scrawl, which explains the oversight by the engraver of GE (→FE,EE,IE).

Pedalling suggested by the editors

..

 in bar 198 is the last sign of pedalling, added and non-deleted by Chopin in GC (in the middle of the next bar one can see a deleted sign, which could have been a  asterisk). It is hard to decide what the reason for stopping the entries could have been, yet the most likely answer seems to be distraction. In any case, it certainly does not mean that one should stop using the pedal. In the main text we add indications on the basis of the authentic pedalling in similar bars 70-80. In GE1 the last written sign was considered to be a mistake and hence omitted, it was however reinstated in GE2

b. 198-199

composition: Op. 35, Sonata in B♭ minor, Mvt II

No tie in GC (→GE) & FE1 (→FE2FE3,EE)

Tie in FE4

..

The tie sustaining b2 was added – most probably by Chopin – in the proofreading of FE4. We consider this change to be a correction of the inaccurate (incomplete) notation both here and in analogous situation in bars 10-11.

Slur in GC (→GE) & FE1 (→FE2FE3,EE)

No slur in FE4

..

Deleting the slur over the three-note motif, totally unjustified, as far as the music is concerned, is a possible result of misunderstanding at the proofreading of FE4, whose aim was addition of the tie of b2. See the adjacent note.
