b. 131

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

..

There is no  before the top note of the last octave in the L.H. – undoubtedly a g – in GC and FE (→EE1). This patent inaccuracy was revised in GE and EE2, however, in GE the  was misplaced in front of in the R.H. (in the sources the bottom notes of the last two octaves in the R.H. are written on the bottom stave).

b. 132

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

Dotted minim in GC (→GE)

Minim in FE (→EE)

Two-part notation suggested by the editors

..

The version of FE (→EE) is most probably inaccurate – cf. bar 131. In the main text we write the chord in the version of GC using two-part notation, in order to facilitate the interpretation and after the previous bars.

b. 132

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

Slurs in GC, FE (→EE) & GE2

No L.H. slurs in GE1

..

The absence of L.H. slurs in GE1 is most probably an engraver's oversight, perhaps provoked by doubts about their placement above or under the notes. The slurs were added in GE2.

b. 132-133

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

Slur in bar 133 in GC (→GE)

Slur from bar 132 in FE (→EE)

..

Taking into account the slur – concordant in the sources – in an analogous situation in bars 124-125, we consider the shorter slur in GC (→GE) to be inaccurate.

b. 133-136

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

Dashes in bars 133-134 in GC

Dashes until end of bar 135 in FE

No dashes in GE1

Dashes in bars 133-135 in EE & GE2

4 bars of dashes suggested by the editors

..

According to us, the differences in the marked range of the cresc. - - - indication are of a random character. In particular, the absence of dashes in bar 136 could have resulted in FE from difficulties in a legible distribution of all elements of the notation of [A] (cf. the notation of GC) or in FE itself, whereas according to Chopin's intention, crescendo was supposed to be valid most probably until  in bar 137. Therefore, in the main text we suggest leading the dashes to the end of bar 136 (see also bars 127-128). The total absence of dashes in GE1 is certainly a mistake (cf. the note on the  hairpin in bars 135-136).
