b. 67

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

 in A (→GEEE,IE)

in FE

Our variant suggestion

..

The comparison with the pianistically analogous passages in bar 65 and 69 suggests that Chopin could have committed a mistake in positioning the  mark in A. Taking into account this possibility, in the main text we suggest a variant solution in which we put the A mark (being the authentic one) in brackets, while the one added by us by analogy with the adjacent passages – in square brackets.
The FE version is most probably an inaccuracy – the reviser would have moved the mark to the end of the bar.

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. 179

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

No marking in A

 in GE (→FE,EE,IE)

..

In the main text we include the  mark added in GE (→FE,EE,IE) after an authentic mark in analogous bar 177.

b. 266-268

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

 in middle of b. 236 & 238 in A 

 at end of b. 268 in GE (→FE,IE)

No markings in EE

..

In the main text we provide pedal markings after A. In the editions they were reproduced erroneously or inaccurately – the  mark in bar 266 was overlooked, while in bar 268 it was placed at the end of the bar (in EE this bar was overlooked too).

b. 270

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

 in A (→GEIE)

No sign in FE & EE

..

The missing  mark in FE and EE is probably an oversight by the engravers; in the case of EE it is already a second oversight of this kind (see bars 266-268). Judging from the version of the aforementioned bars, the A mark could have been written inaccurately (too early); however, in the main text we keep the source notation.
