In this case, it is difficult to attribute the different slurring of FC (→GE) to Fontana's carelessness – he may have assumed that Chopin meant such slurs, separated over the rest. The unequivocal slurs of A probably referred to the initial version of the melody (without rest), yet Chopin did not change them after having corrected the rhythm; moreover, in a few other places, he even combined slurs over rests – see b. 30-31 and 34-35.
