b. 143-144

composition: (Op. 4), Sonata in C minor, Mvt I

No fingering in A (→GEFE,IE)

Fingering in EE

..

In the main text we do not include the inauthentic R.H. part fingering added by EE. See also bars 150-155 and 159-162.

d2-g2 suggested by the editors

According to us, the source version of the 1st R.H. quaver is Chopin's mistake. In A the discussed bar opens a new page, which most probably made it difficult for Chopin to assess the relationship between the preceding quavers and the problematic tritone. Due to the above, in the main text we provide a version modelled after the pianistically more natural version of analogous bars 126-127, in which the tritone opening the new four-bar section is within the range determined by the preceding octave.

b. 143-146

composition: (Op. 4), Sonata in C minor, Mvt I

..

In the main text we omit the unnecessarily repeated flats to d4 in the 2nd half of bar 143 and 145 and to f3 on the 3rd quaver in bar 144 and 146.

b. 144

composition: (Op. 4), Sonata in C minor, Mvt I

Slur to 4th quaver in A, literal reading

Slur to 7th quaver in GE (→FE,EE,IE)

..

The comparison with similar sequences of thirds reveals that the A slur cannot be accurate (perhaps due to ink stoppage). In the main text we provide the GE slur (→FE,EE,IE).
