b.

composition: Op. 23, Ballade in G minor

g3 in A

c4 in FE1

b3 in FE2, GE & EE

..

The version of A is most probably a Terzverschreibung, which would often happen to Chopin with a larger number of ledger lines – cf., e.g. the Polonaise in C minor, Op. 26 No. 1, b. 5 or the Concerto in F minor, Op. 21, II mov., b. 83. Chopin corrected it twice while proofreading FEFE1 includes c4, and it is only just FE2 and the remaining editions that include b3.

b. 1

composition: Op. 23, Ballade in G minor

Largo in A (→FEEE)

Lento in GE

..

Lento could have been entered by Chopin into the proof copy of the Ballade that served as the basis for GE1. However, it is uncertain whether that copy indeed included Chopin's amendments; therefore, the authenticity of Lento remains unsure. Chopin could have hesitated between these two indications – Largo works perfectly with the initial fragment,  and pesante, whereas Lento seems to be better suited to the second phrase, played , imbued with sorrow and resignation.

composition: Op. 23, Ballade in G minor

Title in A (→FEGE)

Title in EE

..

As in many other works by Chopin, EE arbitrarily changed the authentic title of the Ballade, calling it "La Favorite". Cf Nocturne Op. 27 No. 1.

b. 1

composition: Op. 23, Ballade in G minor

..

In A, the pesante marking is written high on the top stave, while its beginning falls over the slur. Such a placement prompted the engraver of FE to put it over the top stave; however, in the stage of proofreading FE1, the indication was moved – probably at Chopin's request – to between the staves, directly over the R.H. part.

b. 4-5

composition: Op. 23, Ballade in G minor

..

In A, bar 4 ends the line. The slur at the end of that bar very clearly suggests that it should be continued; however, it is not confirmed by the slur in b. 5, which begins over the 1st note in the bar. According to us, it is the slur in b. 4 that is reliable, which is how it was interpreted in FE (→GE,EE).
