Change of pedal on e in A (→GE2)

No change of pedal in GE1 (→FEEE)

A, FE (→EE1), GET

GE and EE3

..

In A, the third, sixth and ninth semiquavers form a tenor line e flat-d flat-c. That detail was not repeated in GE, which has e flat in all those places. In the proofing of FE (→EE1) Chopin returned to the version of A, the relevant change was also made in GET. The version of GE was introduced into EE3.
