b. 282-283

composition: Op. 2, Variations, complete

con o in 8va from b. 283 in A & FESB

According to us, the only aim of the version introduced by Chopin into FE1 (→FE2) could have been to specify the notation of GE1, in which the indication begins a quaver too early, while in bar 287 it does not signal the transition to the simple octave sign, resulting from the change of texture to chordal. In other words, it is uncertain whether FE1 (→FE2) omitting the possibility to perform bars 283-286 and the two beats of bar 287 in octaves was not simply a compromise to avoid unnecessary complications of proofreading. Due to the above, in the main text we keep the variant notation of A and FESB. In EE the form of the indication is wrong: con 8ves in 8va; when interpreted literally, it would indicate that the phrase is to be performed both in octaves and an octave higher. In the content transcription (version "edited text") we omit the second, misleading part of the indication.

c2 in AsI & A (→GEEE,FESB)

a1 in FE

In the main text we give the version of FE, which most probably resulted from Chopin's proofreading. However, taking into account the possibility that the note was shifted by a third (by mistake), which is one of the most frequent errors in rewriting and copying notes, we consider the version of the remaining sources (undoubtedly authentic) an equal variant.

We consider the omission of the  mark in this bar by Chopin an oversight, and in the main text we suggest a  in a harmonically natural place.

Slur in EE and FE

GC (→GE)

..

In GC, the slur ends in bar 283 at the end of the page. The fact that it is not continued on the next page is probably an oversight. We adopt the consistent version of EE and FE.

Fingering indications written into FED

..

The signs written in FED under the 4th quaver in bar 283 and under the 2nd and 6th quavers in bar 284 most probably indicate a more convenient performance of the passage consisting in taking these notes over by the L.H. It is not entirely clear what it exactly is – according to us, they are additional quaver flags (cf. the Nocturne in C minor, Op. 27 No. 1, bar 27). We include these meaningful practical hints in the main text.
