The deletions visible in AI allow us, with high probability, to reconstruct a still earlier version of the first two beats in the R.H. part: . Having analysed the changes, we can say that by trying various combinations of g1, c2 and g2 notes, since the very beginning, Chopin had been trying to find both the best sound and the most comfortable piano grip for this figure. In the main text we give the latest version of FE (→GE,EE).

b. 85-87

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

3 slurs after AI

2 slurs in FE (→EEC)

Continuous slur in GE

2 slurs in EEW

..

In AI the slur running further on, to bar 100, begins in bar 87. In FE (→EEC) it is added to the previous slur in bars 86-87. The change of slurring in this place probably resulted from the slowdown of harmonic changes in the final version and the associated introduction of sustained notes to the R.H. part, particularly b1. The version of GE is most probably a mistake – the long slur starts a bar too early, while the absence of the slur in bar 86 EEW is most probably an oversight.
