b. 132-133

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

In the main text we add cautionary naturals to the d2-f2 third in bar 132 and to the c crotchet in bar 133, as well as flats to a2 on the 4th quaver in bar 132 and to d in bar 133. Some of them were added already in GE (→FE,EE,IE) – a  to f2 in bar 132 and both flats. On the other hand, we do not include the  added by the editions to e in bar 132.

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

..

In A each L.H. note on a ledger line – E, C, E, F1 – is provided with a "tail", which, in a relevant context, could be considered an additional crotchet stem pointing downwards. It would make sense in the case of E and F1, but C and E prove that it is simply a writing manner.
Cf., e.g. the Etude in F, Op. 10 No. 8, bars 4-7.
