The version without a slur most probably resulted from an oversight by the engraver of FE (→GE,EE). In the main text, however, we give this version, since Chopin did not restore the slur while proofreading FE, in spite of the fact that he addressed the R.H. slur in the next bar, while in the discussed place he most probably corrected the value of the a1 note (see the next note). The omission of the slur is also supported by the corrections to the top voice slurs, visible in A – the discussed slur was most probably related to the version of slurring Chopin eventually forwent.
