The version of AE with the bottom c2 minim prolonged with a dot is incidental and absent in the other autographs.
In CC, there is a dot next to the topmost note of the chord, a2, which we consider a mistake. In the edition of this source, we suggest a triad with minims.
In CX, there is an additional a1, written as a crotchet in the bottom-most voice in the R.H. In Chopin's manuscripts, one can encounter such chords with different rhythmic values. However, taking into consideration the entire text of CX, in which there are a few examples of wrongly written notes, uncorrected by the copyist, we consider this version to be probably erroneous. In the edition, we suggest a sole c2-a2 sixth.
