b. 111

b. 113

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

..

At the beginning of the bar, A has the tenth a flat2-c flat4, which is an obvious mistake. That error was overlooked in GE1, as both in that edition and in the editions based on it, i.e.  FE (→EE) and GE2 (→GE3), the correct octave a flat2-a flat3 appears.

b. 127-128

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

A probable reading of A (→GE)

A possible reading of  A

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).

We add a cautionary  before g flat.

b. 138

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

..

According to the principles governing use of cautionary accidentals that we have adopted, the  before g flat in the 3rd chord is unnecessary. The reason why Chopin put it in A (→GE→FEEE) was probably the non-typical chord orthography that may bring associations with the diminished triad g - c sharp1- e1. Chopin introduced that enharmonically changed notation in the last phase of writing A, which is testified by the visible deletion of the chord originally written as the previous one.
