b. 5

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

..

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).
