The comparison with analogous bar 8, 182 and 186 indicates that we are most probably dealing with Chopin's mistake, who forgot to write the letter z in the 3rd  mark. Due to the above, we suggest adding it to the main text.

b. 4

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

No marking in A (→GEFE,EE1,IE)

in EE2

..

The fact that the EE2 reviser added an indication cancelling the formally applicable  is justified, since  is most probably a mistake here – see the previous note. According to us, one should probably refer here to the dynamics at the beginning of the Sonata's first phrase, that is . The indication added by EE2 is a compromise solution and does not represent typical Chopinesque dynamic markings – the composer would generally mark the dynamics between  and  as m.v. (mezza voce).

In A the end of tie reaches the next bar. We consider it to be an inaccuracy of notation due to the obvious phrase structure and consistent slurring in almost each out of 11 analogous bars.

We add a cautionary natural before e2. This sign is also supplemented in EE.
