Rhythm

b. 6-8

composition: Op. 24 No. 4, Mazurka in B♭ minor

A minim in A (→GE)

A dotted minim in FE (→EE)

..

In FE (→EE) the upper voice minims at the beginning of bars 6 and 8 are furnished with dots extending their rhythmic values. This contradicts the notation of A (→GE). The error could have resulted from reading the staccato dot on the 2bnd beat as the extending dot for the minim.

b. 10-11

composition: Op. 24 No. 4, Mazurka in B♭ minor

Ties in A and GE2 (→GE3)

No ties in GE1 (→FEEE)

..

We give the text of A as our main text. The absence of the tied octave f2-f3 in GE1 (→FEEE) is most probably a mistake, which is in a sense confirmed by the reintroduction of the ties in  GE2 (→GE3). However, a puzzling fact is the omission of that place in the proofing of FE, and particularly lack of that correction in FED, in which Chopin added a natural in bar 10 and a fingering numeral in bar 11. This may testify to the acceptance by the composer of the version of striking the entire chord at the beginning of bar 11.

b. 10

composition: Op. 24 No. 4, Mazurka in B♭ minor

..

There is no rest in the upper voice in the sources. We add it because in this Mazurka Chopin usually put rests in similar situations.

b. 23

composition: Op. 24 No. 4, Mazurka in B♭ minor

..

In GE1 (→FEEE) the quaver c1 from A was misread as extended to a crotchet with an additional downward stem.

In FED Chopin marked that the grace chord is to be struck simultaneously with d in the left hand. Similarly in bar 32. Cf. Nocturne in D major Op. 27 no. 2, bar12.
