b. 128-129

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

..

In A there is no  to c2 in bar 128, as Chopin considered the accidental to c3 at the beginning of the bar to be valid. GE (→FE,EE,IE) did not add the accidental either. Moreover, in A the  to f1 in bar 128 and the  to e2 in bar 129 are missing; these inaccuracies were corrected in GE (→FE,EE,IE). In the main text we add cautionary naturals to d and d2 at the beginning of bar 129, as well as – in accordance with the rules we adopted to our edition – a  to b2 at the end of bar 129.
