b. 235-238

composition: Op. 31, Scherzo in B♭ minor

No signs in A (→FCGE1, →FEEE)

 in GE2 (→GE3)

..

Two two-bar  hairpins were repeated in GE2 (→GE3) after the authentic marks in b. 103-106.
There is a similar situation in b. 686-689.

b. 235-236

Two-bar pedalling in FC (→GE1)

One-bar pedalling in GE2 (→GE3)

One pedal added by Chopin in these bars in FC (→GE1) is most probably a mistake of the composer. Chopin, being in haste, could have been influenced by previous six bars, in which two-bar pedalling complies with the harmonic content of the L.H. figurations. Therefore, in the main text we suggest two one-bar pedals marked by Chopin in analogous b. 103-104 both in FC (→GE) and FE (→EE). Such a pedalling was also introduced in GE2 (→GE3). A similar situation can be found in b. 686-687.

In the main text we give the  mark entered by Chopin into FC (→GE1). In GE2 (→GE3) the mark was extended so that it encompasses two bars (from b. 239) after the authentic  mark in analogous b. 107-108. A similar situation can be found in b. 690-691.

The version of the majority of the sources, the 3rd chord with g2, does not raise doubts as such. However, they arise when compared with analogous b. 108, in which, after the corrections performed in A, Chopin eventually wrote a chord featuring f2. Actually, the corrections probably concerned the issue of rhythm; however, they guarantee that the b1-f2-b2 chord does not contain a mistake and was intended by Chopin. What is more, had the corrections been performed simultaneously with the revision of the entire manuscript, this version would have been the last one written by Chopin. Taking into account the above observations as well as the fact that it seems highly unlikely that such an insignificant difference could have been intentionally left behind, we consider the version with f2 an equivalent variant. This is the only version that was introduced in GE2 (→GE3).
There is a similar situation in b. 691.
