cre - scen - do in A

cresc. in GE (→FE,EE,IE)

..

The authentic notation, carefully defining the crescendo's range, was simplified to a standard abbreviation in GE (→FE,EE,IE).
Similarly, in bars 30-31.

b. 25

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

..

In the 2nd half of the bar A contains two L.H. slurs, from the 5th to the 10th quaver and from the 7th to the 10th quaver. The first one is deleted by the extension to the slur from the 1st part of the bar, which means that Chopin initially divided the quavers as follows: 4+6 (as in the previous bar), and then changed the division to 6+4, in accordance with the rhythm of the harmonic changes.

 in A, likely interpretation

..

In the sources the  mark reaches , the position of which is, however, ambiguous in A, as it was written over the e1-e2 L.H. octave and a quaver later as well, under the R.H. e2 note. According to us, the mark is supposed to concern the R.H., and this is the interpretation we provide in the main text. Meanwhile, in the editions  was printed on the 4th quaver from the end of the bar, which probably resulted in a respective shift of the  hairpin.

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

Slur from e2 in A

Slur from g2 in GE (→EE,IE)

Tie to b2 in FE

..

In this case, it seems that there are no reasons to doubt the accuracy of the A slur, which encompasses the three-quaver chromatic linking motif between the phrase that just finished and the surprising G chord in the next bar. Therefore, the earlier starting point of the slur in GE (→EE,IE) must be considered wrong, not to mention the completely arbitrary FE version.
