The semibreve in CLI is undoubtedly the original version. In the final version Chopin enriched the sound and made the rhythm more robust. In Ap before the lower note of the first octave is missing. In Ap and FE there is no lowering e1 to e1 on the 2nd beat of the bar. This patent inaccuracy was corrected in GE and EE. In GE3 and EE4 an unnecessary before the 2nd e is also added.
