In the main text we give the dynamic markings written in FEcor, in accordance with the visible in this Etude Chopin's tendency to indicate only general framework of dynamic details. However, the more precise indications of Ap may be, according to us, treated as their completion. In FE (→GE,EE) the dim. indication, written in FEcor in the middle of bar 17, was reproduced a little bit later, on the 3rd beat of the bar.

In FEcor Chopin changed the crotchets in the L.H., included also in CLI and Ap, to quavers separated with rests. It is one of a few changes of this kind; similarly in analogous bar 43.
