R.H. in JC

..

The version of JC and EF, with a clearly audible doubled leading note B-b on the 5th quaver of the bar, is undoubtedly earlier. It is difficult to determine how the difference concerning sustaining the note at the transition between bars 3 and 4 was developed. In PE, the lower note of the last semiquaver was printed on the level of c1, which is certainly a mistake corrected by us into d1.

As far as the time intervals between subsequent R.H. notes are concerned, the rhythm of the first phrase (b. 3-6 and 12-15) is no different in FCI from the one Chopin eventually sent to be published. The crossings-out visible in A in b. 3 confirm that the version without rests, preserved in FCI, is earlier. Thanks to the rests, the theme is more precisely articulated and more volatile at the same time. It is also reflected in the slurring – see b. 12.
An analogous change of notation is also to be found in b. 11.

In the first part of both bars, one can see crossings-out in the R.H. part in A. In b. 3 the correction most probably concerned rhythm – it seems that Chopin started writing the first two notes as a dotted quaver and a semiquaver. The crossings-out in the 1st half of b. 4 could have concerned two rests (a crotchet rest and a quaver one). It would mean that the dotted d1 crotchet and the tie that reaches it were added later. Traces of such minor rhythmic changes can also be seen later on, see, e.g. b. 5 and 8.

The crossed-out g2 note before the final a2 note, which can be seen in A, and the e2 note, added clearly later, prove that the last 3 semiquavers in the bar were initially f2-g2-a2

This bar belongs to one of the few places in which Chopin, while working on this variation, changed the shape of the melody formed by the R.H. topmost notes (see also bars 11 and 24). The interpretation of the AsI notation presents some difficulties, since it is uncertain whether the 3 grace notes, which could have been added later, were supposed to complement the figuration or whether they were an original way to mark the change of concept of the topmost notes to the final version. The latter is supported by analogous bar 20, in which AsI includes the final version entered without hesitation. In either case, the notation of these grace notes is puzzling, since each is provided with a different form: a semiquaver, a slashed quaver, a quaver, respectively. Perhaps Chopin wanted to try out different forms of notation to see which one would suit him best.
Moreover, both manuscripts differ slightly in the version of the 2nd and 4th L.H. figures – see the note below.
