b. 56

composition: Op. 63 No. 1, Mazurka in B major

Longer slur in AI, GE & EEW

Shorter slur in FE (→EEC)

..

According to us, the slur ending in FE (→EEC) before the last note of the motif is inaccurate, most probably due to a wrong interpretation of the notation of [A]. The range of the short slurs encompassing particular motifs introduced in this autograph could have seemed obvious to Chopin, which probably resulted in hasty, not very careful notation. The arguments for leading the slur to the B crotchet are the slur of AI in this place and the slur of FE in a similar motif in bar 54.

b. 57-60

composition: Op. 63 No. 1, Mazurka in B major

Four-bar slur in AI & FE2 (→EE)

Two-bar slur in FE1 (→GE)

..

As in bars 53-56 (see the note on bars 49-56), Chopin completed and proofread in FE2 (→EE) the R.H. slurring, returning to the initial concept of a four-bar slur. This is the version we give in the main text.

b. 58

composition: Op. 63 No. 1, Mazurka in B major

Continuous slur in AI

2 slurs in FE (→GE1,EE)

3 slurs in GE2 (→GE3)

..

As in bars 53-56, the division of the initial slur of AI into 3 shorter ones, encompassing particular motifs, is an element of the change of the general concept of slurring of the middle section of the Mazurka. The missing slur in bar 58 in FE (→GE1,EE) is probably an oversight, corrected in GE2 (→GE3).

b. 58-60

composition: Op. 63 No. 1, Mazurka in B major

d in AI, FE2 (→EE) & GE

d in FE1

..

The version of FE1 is almost certainly a mistake by Chopin, which is proven by the compliant version of AI and FE2 (→EE), proofread by Chopin. The mistake was most probably caused by the fact that in [A] the notation with a 5-sharp key signature (as in AI) was replaced with the notation with a 3-sharp key signature. In the discussed four-bar section, kept in the key of C major, it was necessary to add sharps to d and a notes, which Chopin apparently did not do, since these are the accidentals that are missing in FE1 (see also the last note in the next bar).

b. 59-60

composition: Op. 63 No. 1, Mazurka in B major

Tie in AI & FE (→EE)

No tie in GE

..

The version of GE is an arbitrary revision, probably resulting from an analysis of bars 53-64 in FE1.
