b. 277

composition: Op. 49, Fantaisie in F minor

No sign in A (→GE)

in FE (→EE)

..

In addition to the accent over the R.H. chord – see the preceding note – FE (→EE) also includes a  hairpin. According to us, the presence of two marks may have resulted from a mistake or an attempt to remedy an inaccuracy, hence the authenticity of the mark in this form is questionable.

b. 278-279

composition: Op. 39, Scherzo in C♯ minor

New slur in EE and GC

One slur in FE and GE

..

Both versions of the slurring may be authentic, and the version of FE is probably later. However, the fact that GE - the source that was, after all, based on GC - has a continuous slur shows how easy it was for the engraver of FE to misread the manuscript. Bearing that in mind, we take the slurs of EE and GC as our main text. The practical difference in performance is very slight anyway.

b. 278

composition: Op. 39, Scherzo in C♯ minor

..

In GC, this bar is marked as the repetition of the previous one, which must reflect the notation of the autograph.

b. 278

composition: Op. 21, Concerto in F minor, Mvt I

Long R.H. accent in A (literal reading→GEFE)

R.H. short accent in EE

L.H. long accent in A, interpretation suggested by the editors

..

Same as in bar 130, we consider that it is more likely that the accent refers to the L.H.

..

In A there is no  restoring a. This patent mistake – cf. analogous bar 130 – remained unnoticed by Chopin both during the proofreading and lessons. Revisers of the editions also did not notice it.
