b. 726

composition: Op. 31, Scherzo in B♭ minor

Pedal change on 2nd beat in A (→FEEE)

Pedal change on 1st beat in FC (→GE)

..

An earlier pedal change in FC (→GE) is a result of inaccuracy of the copyist, who probably considered the notation of A to be inaccurate.

b. 730

composition: Op. 31, Scherzo in B♭ minor

..

In A one can see that Chopin started writing the g quaver as a.

b. 730-731

composition: Op. 31, Scherzo in B♭ minor

 on 3rd beat in A (literal reading→FCGE1, →FEEE) & GE3

 on 2nd beat in A (contextual interpretation) & GE2

..

In A the R.H. quavers in these bars are written later than the L.H. part notation indicates, which is one of the reasons hampering the interpretation of the pedalling markings. The  marks begin under the 1st R.H. quaver but they end already after the last L.H. crotchet, which the majority of the sources reproduced as a  mark on the 3rd beat of the bar. Such a pedalling unnecessarily – contrary to cresc. – impoverishes the sound, since, differently than in the previous bars, the first two quavers of each of the passages do not form the chord built with pedal. Therefore, in the main text we keep in these bars the pedalling model from the previous passages, which is pianistically natural and compliant with the notation of A. Such a solution was adopted in GE2, whereas GE3 restored the notation of FC (→GE1).

b. 730-731

composition: Op. 31, Scherzo in B♭ minor

No slur in A (→FEEE)

Slur in FC (→GE)

..

In the main text we keep the slur of FC (→GE), yet it is uncertain whether it was added by Chopin. Anyway, the missing slur in A is probably just an oversight (of Chopin), so it seems justified to add that slur, even if it was added by Fontana.

b. 731

composition: Op. 31, Scherzo in B♭ minor

Staccato dot in A (→FC)

No mark in FE (→EE) & GE

..

The missing staccato dot in FE (→EE) and GE must be a result of oversights. We can excuse the engraver of GE, since the dot in FC looks like the ending of the octave's stem and is hard to perceive.
