The indication 
was added by Chopin in FED, in which there are no dynamic indications both in this (
) and in the next bar (
). Therefore, it is possible that the addition was meant to change the dynamic concept of the return of the main theme of the Etude, written in A and given in the main text. However, it is not the only possibility – the indication may also be considered as clarification of the local dynamic level of the 2nd half of bar 61, not determining the way of performance of bar 62 and subsequent ones. Due to this fact, we suggest a possibility of including independently from the remaining indications.
