b. 130

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

c1-g1 in GE & EE, possible interpretation of GC & FE1 (→FE2FE3)

c1-a1 in FE4

..

On the 2nd crotchet GC and the previous impressions of FE include in the R.H. the clearly erroneous c1-g1. As in the respective place of the previous bar there was c1-gin a similar context, it seems to be required to add a  raising g1 to g1. The addition was actually introduced in EE and GE. However, in the proofreading of FE4 a different changes was performed – g1 was replaced with a1. Both EE and FE4 bear traces of Chopin's intervention, so that each of these versions can be authentic. On the other hand, both sources include changes indicating a revision, hence it is not certain whether and which of them actually comes from Chopin.
In the main text we suggest the version of FE4 due to the unquestionable text at the repetition of this place (bar 170). Cf. bar 131

b. 131

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

f in GE, possible interpretation of GC & FE1 (→FE2FE3,EE1)

e in FE4 & EE2

..

GC and the previous impressions of FE (→EE) include the erroneous as the top bottom note in the chord on the 2nd crotchet. The mistake was revised in GE, adding a  before this note, which has to be considered to be justified. However, the comparison with analogous bar 171, and, above all, the change introduced – probably by Chopin – in FE4 convinces that the mistake concerned the pitch and not the missing . The version with e was introduced also in EE2, most probably on the basis of FE4. According to us, both here and in the previous bar, we are dealing with Chopin's mistakes in [A].

b. 145-147

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

Slur in bars 145-146 in GC (→GE)

No slur in bars 145-146 in FE1 (→FE2)

Tenuto slur in FE3 (→FE4)

Slur in bars 145-148 in EE

..

Both notations of the slur in bars 145-146 – GC (→GE) and FE3 (→FE4) – mean generally the same, yet the notation used in FE accentuates the necessity of holding the full rhythmic value of the chord in bar 146, which is often not observed in the case of the last note under the slur. Chopin would often use this notation, cf., e.g., 1st mov., bar 176, the Etude in A minor, Op. 25 No. 4, bar 50, in C minor, Op. 25 No. 7, bars 22, 24, 28 and 30 or the Mazurka in B minor, Op. 33 No. 4, bars 2, 4 and analog.
The slur in EE may be a result of an erroneous interpretation of the tenuto slur written by Chopin in the base text – as in FE3 – as an extention to the previous bars of the slur in bar 147.

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.

b. 222-224

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

Slur in GC

No slur in FE! (→FE2)

Slur in GE & FE3 (→FE4)

Slur in EE

..

The slur added – most probably by Chopin – in the proofreading of FE3 (→FE4) clearly shows that according to the composer's intention, it was not supposed to reach the next bar. The longer slur of EE may be considered in this situation an inaccurate interpretation of the slur added in the base text by Chopin (cf. bars 36-37) or an editorial revision on the basis of the analogous place of the first section of Scherzo.
