b. 148

composition: Op. 38, Ballade in F major

..

In A the only accidentals in this bar are two sharps: before G at the beginning of the bar, and g in the R.H. The  before the bottom note of the octave was added in all remaining sources. Besides this  Chopin wrote into GC three more naturals, before the 1st semiquaver (b), and before the last octave (B1-B). GE supplemented the record of GC with a  before b at the start of the 2nd half of the bar (this note is written in the sources on the lower staff). That  was also added in FE2 (→FE3) and EE. The latter further added only both accidentals at the beginning of bar leaving the last octave without naturals.

b. 148

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

d2-g2 in GC, FE (→EE) & GE2

b1-g2 in GE1

..

The version of GE1 is certainly a mistake of the engraver, corrected in GE2. The bottom note of this dyad is devoid of natural in GC, FE and GE1, which in all of the cases is a patent error.

b. 148

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

Slur up to 2nd beat in GC

Slur up to 3rd beat in GC (another interpretation→GE), FE & EE

..

The inaccurately vertically written notes result in GC not being entirely clear where the slur over the part of the R.H. is supposed to reach – the 2nd or the 3rd beat of the bar. In the main text we adopt the first possibility, in which the relation to the progression of the bottom voice is more significant. In the editions it was interpreted differently, which is also justified, particularly if we take into account the tenuto slur, added by Chopin in the proofreading of FE3 in bar 146.

b. 148-152

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

In the sources based directly on [A] – GC and FE1 (→FE2FE3,EE1) – four naturals raising c1 to c1, in bars 148-149 and 151-152, are missing. These patent inaccuracies were corrected in GE, FE4 and EE2
