GC - Gutmann's copy
Prezentacja
Select
FE and GE have a double bar line between those bars. In the case of GE, this is definitely a revision (in GC, its base text, the bar line is single). This makes us suspect that the version of FE may also result from a routine editorial revision. Chopin used double bar lines infrequently and never treated them as necessarily connected with the change of key.
