11 staccato dots in FC

11 dots in GE1

14 dots in GE2

16 dots suggested by the editors

..

Staccato dots under (over) the bass notes are present in this theme both in FC and FE in the vast majority of cases (we take into account both the discussed bars and their counterparts upon the return of the theme (bars 79-94). The distribution of the bars devoid of dots is certainly accidental, hence in the main text we give them in all bars.
In GE1 and EE the versions of FC and FE, respectively, were inaccurately reproduced. In GE2 the majority of the dots missing in GE1 were added.

 in A, contextual interpretation

No sign in FC (→GE), FE (→EE) & CGS

..

Like in the previous two bars, we assume the bottom arm of the  hairpin in A to be reliable. The mark is absent in all the remaining sources, which is almost certainly a result of oversights:

  • A few overlooked elements prove that Fontana was distracted at the time of writing the last line of FC – in addition to , it is also the L.H. slur and dashes marking the range of crescendo that are missing.
  • While working on the last line, the engraver of FE probably omitted the stage of adding dynamic markings, since the  hairpin is neither in b. 10 nor in b. 11.

Dashes in A (→FEEE)

No dashes in FC (→GE)

Dashes in CGS

..

The missing dashes marking the range of cresc. must be an oversight of Fontana in FC (→GE). In CGS the dashes reach only the middle of the bar, which is one of many minor inaccuracies of that copy.

Slur in A (→FEEE)

No slur in FC (→GE)

..

The missing slur in FC (→GE) is an oversight of Fontana. The slur of A was being extended so that it could also encompass the last crotchet in b. 12. The added fragment ends already in the next bar, in which, however, there is not a single element of notation to which it could have been led. Therefore, it is simply an inaccuracy, quite frequent for Chopin.
