b. 53-54

composition: Op. 50 No. 1, Mazurka in G major

..

The cautionary naturals before c2 in b. 53 and g1 in b. 54 were added – most probably by Chopin – in the proofreading of FE (→EE).

b. 54-55

composition: Op. 50 No. 1, Mazurka in G major

e2 tied in A1 (→FEEE) & GE1

e2 repeated in GE2

..

The missing tie of e2 in GE2 is probably down to a combination of two factors:

  • wear and tear of the plate of GE1: in b. 54 (at the end of the line) the tie of GE1 is imprinted so unintelligibly that it is actually imperceptible;
  • in b. 55 there is no continuation of the phrase mark from the previous bars in GE1.

Consequently, the engraver of GE2 considered the ending of the tie of e2 in b. 55 to be the ending of the phrase mark and moved that little slur higher, over the quaver beam (that slur is included in the note on the curved lines in b. 55-57).

b. 54

composition: Op. 50 No. 1, Mazurka in G major

Slur in A1 & GE

No slur in FE (→EE)

..

The missing L.H. slur in FE must be an oversight of the engraver.

b. 54

composition: Op. 50 No. 1, Mazurka in G major

..

The rhythmic notation of the 1st beat of the bar in FE2 is completely erroneous: both the stem and the quaver beam of the upper voice on the 1st beat of the bar were overlooked, as a result of which the e quaver looks like a crotchet.

composition: Op. 50 No. 1, Mazurka in G major

2 slurs in A1

Continuous slur in FE

Slur from f1 in bar 57 in GE1

Probable slurs in [A2], our alternative suggestion

Slur from d1 in bar 57 in EE

Slur to e2 in bar 55 in GE2

..

Except for the versions of GE1, GE2 and EE, which are clearly erroneous and which overlooked some of the curved lines, there are most probably three authentic versions of slurring for these bars: A1[A2] and FE, proofread by Chopin. We do not know [A2] directly, yet one may closely reconstruct it on the basis of GE1 and the remaining authentic versions: since there are no notes that would not be encompassed with a slur in A1 and FE, it was most probably also the case of [A2], which means that the continuation of the slur from b. 53-54 overlooked in GE1 led to the first crotchet in b. 57. This version may be considered an equal variant with respect to the main text, which we hold for the version of FE, the latest of the three authentic ones, introduced probably instead of the version of A1 (perhaps incomplete, which may be indicated by the text of EE).
