b. 11

composition: Op. 28 No. 9, Prelude in E major

 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.

b. 11

composition: Op. 28 No. 9, Prelude in E major

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.

The cautionary sharp before f is present in all sources except for EE1. It means that the overlooked, and perhaps removed accidental, was then added in EE2, perhaps as part of the comparison of the text with GE1, undertaken in EE2.

b. 11

composition: Op. 28 No. 9, Prelude in E major

..

In A (→FE) and CGS, there are no accidentals in the L.H. part in the entire bar. Chopin's patent inaccuracy was corrected by Fontana in FC (→GE), who added naturals lowering G1-G to G1-G and D1-D to D1-D. An identical addition was introduced in EE. The accidentals were also added in FED.
