b. 15

composition: Op. 2, Variations, complete

One group of notes in AsI

Triplets & quintuplet in A (→GEFE,EE,FESB)

..

The division of the figuration is an evident improvement of notation, since it corresponds to the rhythmically well-determined melodic and harmonic structure of the figuration. According to us, the change of slurring introduced in the last stage of shaping the note image of this bar explains why Chopin initially wrote down this bar as one group – he did not want to indicate rhythmic divisions, since the divisions of motifs fall on other places.

b. 16-17

composition: Op. 2, Variations, complete

Crotchets after minims in AsI

Crotchets after minims in A (→GEFESB)

Crotchets and minims together in FE & EE

..

Due to small gaps between the notes in GE1, the minims and the following dotted crotchets are written very close to each other; consequently, FE and EE interpreted it as a cue to combine the voices, which, in turn, led to the two notes being played simultaneously. In subsequent bars, a similar situation can be observed.
