Dots in GE2 (→GE3)

..

In A, the quavers a flat at the beginning of those bars have wedges;  in GE1 the wedges were omitted. In FEstaccato dots were added instead, which is most probably the result of Chopin's intervention. Dots were also added in GE2 (→GE3). Absence of any signs in EE might mean that some of the changes in FE were introduced after copies had been sent to London as base texts for EE1.

As the 2nd crotchet A (→GE) has the chord e flat-g flat-c1, as in the previous bar. In the proofing of FE (→EE) Chopin added the note A flat and the arpeggio wavy line.

A probable reading of A (→GE)

FE (→EE1EE2)

A (→GE) has triads as the 2nd and the 3rd crotchets of those bars, although in the first triad in bar 127 the note c1 is practically invisible in the manuscript. When proofing FE, Chopin removed the middle notes of the triads leaving only the sixths. That corrected version was repeated in EE1 (→EE2). EE3 returned to the version of GE1 with the full triads (the omitted note b flat on the 2nd beat of bar 128 must be a mistake).

b. 138

composition: Op. 24 No. 4, Mazurka in B♭ minor

..

In A (→GE), there is a  entered before d flat1 in the 1st chord. That sign, totally unnecessary in the context, was removed in the proofing of FE (→EE), perhaps at Chopin's request. It is conceivable that the much more clearly written  lowering f1 to f flat1 in A was, in Chopin's intention, to replace the sign put mistakenly before d flat1.

Chopin added the marking  in the proofing of FE. In EE it was split into two separate parts, with  allocated to the bass note and  to the following chords, which in this case corresponds to the actual performance.
