b. 413-435

composition: Op. 31, Scherzo in B♭ minor

1 long, 9 short accents in FC

9 short accents in FE

10 short accents in GE1

10 short accents in EE

12 short accents in GE2 (→GE3)

12 long accents suggested by the editors

..

The accents written in A in b. 413, 415 and analog. mean almost certainly the same despite differences, generally minor ones, in length and shape. The majority of the marks is rather short; however, four (b. 417, 425, 433 and 435) are definitely long, which makes us provide the main text with long accents only. At the same time, we add the accents Chopin overlooked in b. 419 and 431. We consider the version of GE2 (→GE3) with a complete set of short accents to be an alternative solution.
The mark in b. 435 was overlooked in FE (→EE), whereas the mark in b. 419 was added in EE

No signs in EE

 & accent in GC & FE

  in GE

..

No marks in EE may come from the earlier version or be an omission. A mark in GC, rightly interpreted in b. 73 in GE as a long accent, here (b. 415) was extended to almost whole bar hairpins.

composition: Op. 39, Scherzo in C♯ minor

Slur in EE and FE

GC (→GE)

..

Slur in GE (→GE) seems imprecise, which is confirmed by the consistent versions of EE and FE.

b. 414-423

composition: Op. 21, Concerto in F minor, Mvt III

..

In the main text we add cautionary flats before bat the beginning of bars 414, 415, 422 and 423. In the first two bars, the signs are present in EE3. Chopin wrote a respective  in A in the last appearance of a similar situation, in bar 463.

b. 414

composition: Op. 21, Concerto in F minor, Mvt III

..

In FE (→EE1EE2) a  was placed before b2, which is a mistake. Such a developed version, with a b2-dthird, is conspicuous only when performing the piece with orchestra (din the viola part), which may have contributed to the absence of a correction in EE1, generally carefully revised. In EE3 the  before b2 was preserved; in addition, a second one was added, lowering d3 to d3
