b. 86

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

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.

The energetic and spectacular ending of the Mazurka was created only just in the stage of writing [A]. In the initial version, the last two bars were actually a repetition of the two preceding ones, probably supposed to be more distant and calmer.
