b. 86

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

Without grace note in AI, FE1 (→GE)

Acciaccatura in FE2 (→EEW)

Appoggiatura in EEC

..

Chopin added the grace note while proofreading FE2 (→EEW), which we introduce to the main text, since it is the latest version of an enhancing nature. The change of the type of grace note in EEC is a manner of the engraver, who did not use a slashed grace note in this Mazurka even once.

In AI, as in bar 84, Chopin wrote 2 versions of the 1st and 2nd beats of the bar consecutively. The one he did not delete was then replaced by the FE1 version (→GE). As far as the change of the g1 semiquaver to a1 in the proofreading of FE2 is concerned, taking into account the earlier changes, one can have doubts whether it corresponded to Chopin's intention. The aim of the proofreading was the addition of a grace note, and this required the semiquaver to be moved to make room for the added note. Practically, such a 'shift' means that a note has to be removed and then re-inserted in a different place, which provides an opportunity for mistake. Therefore, we do not include this change in the main text; however, we consider it an equal variant.

FE (→GE,EE)

In AI the ending of the Mazurka is 4 bars shorter – bars 88-91 are absent, while bars 87 and 92 are present in a different form, which makes it possible to put them together directly adjacent to each other.

c1 tied in FE (→GE,EEC)

c1 repeated in EEW

..

The missing tie in EEW is a revision or an oversight by the engraver, taking into account the separation of the middle L.H. voice introduced by this edition. In AI bar 91 is absent (and the three preceding ones too) – see bar 87.
