In A (→GE), there is a entered before d flat1 in the 1st chord. That sign, totally unnecessary in the context, was removed in the proofing of FE (→EE), perhaps at Chopin's request. It is conceivable that the much more clearly written lowering f1 to f flat1 in A was, in Chopin's intention, to replace the sign put mistakenly before d flat1. category imprint: Differences between sources issues: Cautionary accidentals , Authentic corrections of FE |

In A (→GE1→FE) there are no naturals raising d flat-d flat1 to d-d1. This obvious omission on the part of Chopin was corrected in EE and GE2 (→GE3). category imprint: Differences between sources |
