b. 99

composition: Op. 50 No. 3, Mazurka in C♯ minor

No marking in AI & GE

continued in AF

in FE

Accent in EE

..

The mark in this bar is a continuation of the  hairpin (long accent) from the preceding bar, which falls at the end of the page in FE (→EE). EE feature here a short accent, like in the preceding bar. In the main text we give the version of GE, which do not contain any mark in this bar (after the long accent in b. 98).

Slur to b in AF (→FEEE)

Slur to c1 in GE

..

The shorter slur of GE is an inaccuracy, probably related to the transfer of b in b. 101 to the top stave.
This section of AI (like almost the entire Mazurka) is devoid of all performance indications except for the R.H. slurs.

 suggested by the editors (AF in bars 8-9)

..

A comparison with other sources, as well as with the notation of both autographs in analogous b. 8-9, suggests that the  hairpin is too long here in AF. Due to this reason, in the main text we suggest the notation used in an analogous place the first time, which is substantially consistent with the notation of GE1.

Overlapping slurs suggested by the editors

..

In AF one can see a correction of slurring in this place – the slurs, initially separated by a bar line (like in AI), were then combined. According to us, hesitation about the range of these slurs, visible in this and analogous places (b. 8-9), does not allow us to consider this correction to be final, since Chopin corrected only one of the versions of the divided slurs. In addition, in b. 8-9 the same slurring was probably corrected by Chopin in a different manner, although actually resulting in the same effect. Taking into account the above, in the main text we give the version that was corrected later. The versions of FE and GE may be considered equal variants.

No mark in AI & GE

Staccato dot in AF (→FEEE)

..

The lack of staccato dot in GE must be recognized as an oversight by the engraver or Chopin himself – GE has the mark in the analogous b. 9.
