b. 136

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

in EE

[] suggested by the editors

..

In this context, there is no doubt as to the moment in which the pedal should be released (changed). Therefore, the omission of the  mark in A (→GEFE,IE) – in the light of further, complete markings – must be considered Chopin's inadvertence. The mark was added only in EE.

b. 136

composition: Op. 12, Variations in B♭ major

No slur in FE (→EE)

Slur in GE

..

There is no doubt that the omission of the slur in FE (→EE) was accidental – cf. the adjacent bars, particularly the first appearance of this phrase (bars 117-120). The slur was added in GE, perhaps at Chopin's request.

b. 137

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

A short accent in A (→GEFEEE)

Our proposition

..

The accent that can be seen in A (→GEFEEE) must be considered a short one. However, if we compare that bar with bars 121, 127 and 133, in which A clearly has long accents, we begin to suspect that the accent mark may have been written by Chopin in a hasty and inaccurate manner.

composition: Op. 38, Ballade in F major

We add the cautionary naturals next to F-f. A similar addition was performed also in GE2 (→GE3).
