As in bar 7, in A Chopin changed the position of the R.H. hemidemisemiquaver figures, thus bringing them closer to the melody semiquavers.

Repetition of b. 9-24 in AsI

No repetition of b. 9-24 in A

As in bars 1-8, in AsI it is also the entire second part that is repeated (from bar 9), as proved by two versions (volte) of bar 24 – the first one links bars 23 and 9, while the second is an equivalent of bar 24 in A.

In the principal AsI version, the last bar of this variation does not differ from the previous ones in terms of texture. However, on the adjacent staves, an idea for a new ending was drafted. What is more, Chopin introduced there a correction to the first L.H. triplet: B1-D-F (as in A) was changed to B1-F-B, resulting in – assuming that the passage should be performed with pedal, which is quite obvious – a more harmonised sound of the whole. It is difficult to say why Chopin did not include this correction in A; nevertheless, we consider both versions to be equal.

b. 24

composition: Op. 2, Variation IV, primitive version

..

In AsI, in the 1. volta of this bar, the last 2 hemidemisemiquavers in the 4th R.H. passage are written as c2-a1. This is Chopin's mistake that remained uncorrected – cf. bar 8 (2. volta), in which the same mistake was corrected. Probably while drafting this place, Chopin initially planned to use an F major chord before writing a new version, based on a B major chord, only in the L.H. part, which required more serious alterations, that is change of the bass note and the passage position.
