b. 686

composition: Op. 31, Scherzo in B♭ minor

c1-c1 in A (→FCGE)

c1-b in FE

b-b in EE

The version of FE is almost certainly erroneous, in spite of the fact that it was proofread; originally, in FE this bar was identical to the next one, yet it was only the 3rd note that was corrected, perhaps due to misunderstanding Chopin's proof entry or due to an incomplete implementation of the proofreading. EE repeated the version of FE from before proofreading, which, unless it is an extraordinary coincidence, means that it was a change introduced in the last phase of proofreading.

b. 691

composition: Op. 31, Scherzo in B♭ minor

b1-g2-b2 in A (→FCGE1, →FEEE)

b1-f2-b2 in GE2 (→GE3)

..

Due to the reasons discussed in b. 240 (the discussed bar is an exact repetition thereof), we consider the version of GE2 (→GE3) to be an acceptable variant.

b. 706

composition: Op. 31, Scherzo in B♭ minor

g2-c3-g3 in A (literal reading→FEEE)

g2-c3-g3 in FC (→GE)

..

In the main text we give the version of the principal source, i.e. FC (→GE). Although the naturals visible in the copy were almost certainly written by Fontana, the fact that Chopin carefully revised the entire copy allows us to assume that the composer accepted that addition. The version is also supported by a more natural development of the melodic line: in final progressions Chopin uses a rhythmic cell consisting of 3 repeated notes, which in b. 705 awakens expectations of continuation with the use of a chord featuring g2-g3. EE2 (→EE3) arbitrarily added cautionary flats before the discussed notes.

In FE (→EE) the topmost note of the 1st chord is an erroneous a3 instead of b3.
