b. 147-158

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

..

In these bars it is only the top notes of the octaves that are provided with accidentals in A. This simplified notation was supplemented in GE (→FE,EE,IE) by adding all the missing accidentals.

b. 152

c2 w A

c2 in GE (→FE,EE,IE)

..

The version featuring c2 introduced by GE (→FE,EE,IE) must be erroneous. Bars 151-153 are filled with a dialogue between diatonic motifs in the keys of E minor/G major, setting the stage for the transition towards the key of D major abounding in altered leading tones (bars 154-155). Nothing suggests that Chopin would have wanted to disrupt the tonal stability with a temporary allusion to the key of B minor already in the discussed bar.

a2-c3 in A, contextual interpretation

c3-c3 in GE (→FE,EE,IE)

..

The way the 3rd quaver in the bar was written down in A is unclear – one can see a protrusion before the c3 minim, resembling a quaver notehead at the same pitch, while the presence of an a2 quaver is unobvious, since the protrusion of the stem indicating the presence of a notehead is imperceptible. Consequently, in GE (→FE,EE,IE) both voices coincide on c3, while a2 is totally absent. In the main text we provide a different interpretation of the A notation – we consider the c3 quaver a remaining element of the initial version (or erroneous) of notation without the note having been prolonged, while in the bottom voice we put a2, which – as resulting in a more natural melodic sequence in this voice – is, according to us, written here.
