b. 2-12

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

..

In the ascending passages in bar 2, 4, 10 and 12 Chopin entered accidentals into A only in the first half of each bar, considering them valid also later on in the bar, next to notes placed an octave or two octaves higher. All the necessary accidentals were added in GE (→FE,EE,IE).

In A the  restoring B in the chord in the middle of the bar is missing. In A these accidentals are also absent the next two times this phrase appears, that is in bar 188 and 371. Nevertheless, the harmonic context indicates that it is a patent mistake by Chopin, which he committed earlier, perhaps when writing this movement as a draft, in which the subsequent appearances of this bar could have been marked in shorthand as repetitions of the first appearance. The flat was added in GE (→FE,EE,IE).
