b. 137-138

composition: Op. 2, Variations, complete

..

In AsI the accidentals restoring c1 and b at the end of b. 137 are missing; the  raising e1 to e1 in b. 138 is absent too. A similar situation occurs in the L.H. part, which is marked in an abridged manner as doubling in unison the R.H. part. In A and the editions the notation is correct.

 in A is placed before the last chord of the L.H. but after its initial deleted version. In the editors' opinion, when changing the notation of the chord Chopin failed to notice the consequent change of the spatial relation between that crotchet  and the . That is why in our main text we put the  after the 3rd crotchet. In GE (→FE) the sign was placed under the 3rd crotchet, and in EE even before it.

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.

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.

Slurs in GC, contextual interpretation

Less probable reading of GC (→GE)

Slur in EE and FE

..

Bar 139 is not embraced with any slur in GC: the slur from the preceding bars reaches only to the end of bar 138 (the last bar on the manuscript page) and a new slur begins as far as bar 140. We think that, since the slur in bar 138 indicates continuation, one should assume that it was supposed to reach the minim in bar 139. GE has got a different reading of those slurs; one of them ends in bar 138 and another one begins in bar 139. In EE and FE the slur is not divided, which is probably another authentic version of the slurring, alternative to the version of GC.
