In AsI the 4th hemidemisemiquaver figure in bars 1 and 5 is the same as the third one, although the semiquaver ending the passage is different – D instead of B
1. Moreover, this semiquaver was changed in the stage of writing AsI, which is proven by the visible corrections to this note in bars 1 and 21. Back then Chopin settled for the correction of the bass line only, since in the stage of writing AsI he would use other intervals than an octave between the last hemidemisemiquaver and the following semiquaver much more frequently than in the final version.
