The grace note added in FED is placed inaccurately, so that one does not know whether it is or (or g). In face of such a significant doubt, we do not include this addition in the main text, particularly due to the fact that the most likely interpretation of the grace note – as a – indicates a way of beginning the trill compatible with the classical rule, which Chopin generally used, hence not requiring an additional marking.

The visible in FED deletion of the second of the grace notes indicating the beginning of the trill does not influence the performance, yet it proves that Chopin notation was incomprehensible already for some of his pupils. The notation – indicating the beginning of the trill from the bottom second  – remains one of the most frequent reasons of misinterpretation of the Chopin text.
