b. 5

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

 over f in AI & GE3

 under d1 in FE (→EE,GE1GE2)

..

In FE the mordent was placed under the d1-f1 third, which suggests that it concerns the bottom note, d1. It must be a mistake – cf. the text of AI and bars 13 and 73 – caused by a tendency to place marks, e.g. accents, staccato dots, slurs or certain ornaments ( and ) on the side of noteheads. In the case of ornaments and slurs, it can change their meaning, thus leading to a mistake, as is the case here (see also, e.g. the Polonaise in F minor, Op. 44, bar 10).
There is a similar situation in bars 7, 71 and 75.

b. 7

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

b-c1 in AI, FE2 (→EE) & GE3

c1-d1 in FE1 (→GE1GE2)

..

The c1-d1 second in FE1 (→GE1GE2) must be a mistake (most probably by the engraver), which is proven by b-c1:

  • present in AI,
  • introduced by Chopin in the stage of proofreading FE2 (→EE),
  • present in all sources in bar 75 (upon repetition of this place).

The correct text of GE3 most probably resulted from the fact that a copy of FE2 was used in the revision.

b. 7

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

Slur in AI

No slur in FE (→GE,EE)

..

In the main text, after a comparison with similar bar 75, we insert a slur after AI. The absence of the slur in FE (→GE,→EE) is probably an oversight, perhaps present already in [A].

b. 7

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

 over d2 in AI & GE3

 under b in FE (→EE,GE1GE2)

..

As in bar 5, the  having been placed under b resulted from a routine revision of FE (→EE,GE1GE2). The misleading notation was corrected only just in GE3.

b. 7-15

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

..

In bars 7 and 15 the sources do not contain sharps over the mordents. There are no doubts as to the sound of the top note, while the notation is inaccurate, as usual in such situations in Chopin's works (in bar 7 it concerns only AI and GE3 due to the misplaced  mark in the remaining sources). In the versions 'edited text' and in the main text we add the absent accidentals.
There is a similar situation in bar 75.
