b. 22

composition: Op. 31, Scherzo in B♭ minor

Wedge in A

Dot in FC (→GE)

No mark in FE (→EE)

..

In A the staccato marking with which Chopin provided the last octave looks like a small wedge. However, in the subsequent appearances of this motif, i.e. in b. 46 and 154, the composer used a dot; thus, we give it in the main text. After all, Chopin did not question the dot present in FC, although he had the opportunity to do so, since the extension of the slur proves that he paid attention to that motif while proofreading FC. The dot is also supported by the situation in the last analogous place: in bar 605 the mark overlooked in A was most probably added by Chopin in FC and it is a dot.

Long accent in FC

The interpretation of the notation of A is problematic here: b. 30 ends the line, and the  mark goes far beyond the bar line (in b. 31 there is already no mark). We assume that it is a one-and-a-half-bar mark, like in GE2 (→GE3). In the main text, in accordance with the analysis of the Chopinesque  or  marks in this and analog. pairs of bars (see b. 6-7), we give here an averaged, more or less one-bar hairpin of EE. According to us, all marks, regardless of their actual length, should be interpreted here as long accents.

composition: Op. 31, Scherzo in B♭ minor

 in A (→FEEE1EE2)

  in FC (→GE) & EE3

..

The missing  in A (→FEEE1EE2) was probably overlooked by Chopin: the bar closes the page, which favours distraction. The mark was added in FC (→GE) and EE3.

The manuscripts are missing the  before the bottom note of the 1st chord in the R.H. The patent inaccuracy was corrected both in FE (→EE) and GE.
