b3 in CLI & EE

..

The b3 note on the last semiquaver in CLI and EE seems to be a mistake – the copyist, or maybe the engraver, could have not realised the irregularity of figurations in this place. However, one cannot exclude that CLI transfers the original version of the note, while in EE we are dealing with an editorial revision. Cf. bars 5 and 53.

In CLI all bass octaves in these bars are written in an abbreviated form using the digit 8. In FE (→GE1GE2GE3) such notation was used only in bars 30-31.

In EE2 the octaves in the L.H. in these bars are linked with ties. It is probably a mistake – the ties were supposed to be put one line above as ties sustaining the G1-G octave in bars 27-28. The assumption is confirmed by a joint review of both places in EE3 (→EE4): the ties in bars 30-31 were removed and added in bars 27-28.

Due to the lack of generally recognised rules concerning accidentals, the sources differ in this respect. However, the differences do not influence the interpretation of the text. The layout of the accidentals adopted in the main text can be found in GE4 (→GE5).

Apart from the fingering of FE (→GE,EE) given in the main text, which certainly comes from Chopin, Fontana proposed an additional, alternative solution in EE.
