Crotchets in CLI & Ap

Different values in FE (→GE,EE

In CLI there are no naturals returning a1 and d2. The accidentals were also originally absent in FEcor, in which Chopin added both these two naturals and a third one returning f2 on the last semiquaver in the lower voice. Eventually, both FE (→GE,EE) and Ap have the correct notation.

A cautionary natural before c1 in the L.H. was added in one of the last proofreadings of FE (→GE,EE). The manuscripts do not include an accidental in this place.

Staccato dots in Ap

FE (→GE,EE

..

In bars 40-41 and 43-44 all staccato dots in the part of the L.H. were written by Chopin himself in FEcor (→FEGE,EE). The overlooked – most probably inadvertently – signs in bar 42 were added in a later proofreading. Ap has the marks only on odd beats of the bar (as in bar 38) and only in bars 40 and 42. For a dot at the beginning of bar 41 see note to this bar.
