b. 358-359

composition: Op. 11, Concerto in E minor, Mvt III

..

In FE, the passage was probably reproduced strictly after [A] – it is missing naturals before the 4th, 9th, 11th and 12th semiquavers in bar 358, whereas in bar 359 accidentals are present only before the first two semiquavers. In the remaining editions, naturals were added – GE added all of them, while EE the majority of them (without the 4th and 9th notes in bar 358).
