The e2 note, featured in GE instead of d2, could be a version prior to the last Chopinesque proofreading of FE (→EE). However, the presence of an accent over this note in GE, which, according to us, makes sense only above d2, suggests that the FE copy serving as the basis for GE included d2, hence e1 is rather a mistake by the GE engraver or even a revision. The accent is a strong argument for d2, present in FE (→EE), while the accuracy of this note is also confirmed by the fingering digit entered into FEO (included in the main text).

b. 134-140

composition: Op. 12, Variations in B♭ major

..

Most of the wedges present in FE (→EE) were arbitrarily changed to staccato dots in GE – see the note in bar 7. As the change covers all wedges included in GE, we consider the version of this edition to be one variant, on this page encompassing generally 4 marks in bar 134 and 139-140, yet we discuss the L.H. mark at the beginning of bar 140 separately due to other source issues.

b. 134-135

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

..

In the main text we add cautionary accidentals – a  to E and a  to D in bar 134 and a  to f2 in bar 135. The first one was also added in GE (→FE,EE,IE). By contrast, we omit the naturals (cautionary?) entered into A to both a2 in the 2nd half of bar 134. The second natural was also omitted in GE (→FE,EE,IE).

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

In A Chopin wrote accidentals only to the first note of each pair of quavers constituting an octave – F1ag1. The respective accidental for the second quaver in each pair was added in GE (→FE,EE,IE).
