b. 128-131

composition: Op. 2, Variations, complete

No octaves in AsI

No octaves after AsI

Octaves in A (→GEFE,EE,FESB)

Octaves after A (→GEFE,EE,FESB)

..

In A the L.H. octaves are written in an abridged manner with the use of the con 8va indication. The editions explained the abbreviation. The absence of the indication in AsI may be an earlier version or a simplified notation of the obvious.

b. 128

composition: WN 29, Waltz in E minor

No mark in sources

Accent suggested by the editors

..

In the main text we suggest adding an accent after the previous 3 bars. The absence of the mark is probably an oversight by the engraver, who overlooked it in a new line.

in A

in GE1 (→FEEE)

An alternative proposed by the editors

..

In  A, the dashes marking the extent of dim. appear only in bar 129. This may suggest limiting the binding scope of the dynamic change to that bar alone, which does not seem justified from the musical point of view considering the  in bar 131. In our opinion, inaccurate notation may be suspected here, and therefore we suggest adding the dashes in bar 130. In GE (→FEEE) the dashes were omitted entirely, a frequent error found in the editions. In GE2 (→GE3) Chopin's dim. was replaced with the equivalent abbreviation dimin.

For our main text we adopt the version of GC. That version was also reproduced in GE, albeit inaccurately (the slur in bar 135) and it was additionally revised in GE2 (dots in the L.H. in bars 129-130). The notation of EE may also be considered a less accurate rendition of that version. The long slur of FE was added in print, probably at Chopin's request, and replaced a shorter one beginning from bar 134, which was definitely erroneous. That version should be therefore considered an alternative authentic approach to phrasing and articulation markings for that fragment.

b. 129

composition: Op. 39, Scherzo in C♯ minor

Staccato dots in EE, GC & GE2

No marks in FE

Dot in GE1

..

We consider the question of articulation and phrasing to be independent of the choice of the rhythmic variant. That's why we include the staccato dots in our main text despite the fact that they are absent from FE, i.e.  the source whose rhythm we adopt as the basic one.
