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. 7

composition: Op. 23, Ballade in G minor

e1 in A (→FEEE1EE2)

d1 in GE & EE3

..

The version of GE may be either a revision of this edition (cf. the comment on b. 45-47) or a variation introduced by Chopin (e.g. along with Lento – cf. the comment on b. 1). The vast majority of arguments are for the former, i.e. for this chord being arbitrarily revised in GE:

  • clear notation of A, repeated without changes in FE, which was proofread by Chopin twice;
  • testimonies of Chopin's pupils and friends – Marcelina Czartoryska, Friederike Streicher, Ferdinand Hiller and Adolf Gutmann.

Therefore, in the main text we give e1, considering d1 a variant of uncertain authenticity.
The change in EE3 must have been introduced on the basis of a comparison with GE.

b. 14-16

composition: Op. 23, Ballade in G minor

..

In A, one can see deletions of the bottom notes on the 2nd and 3rd crotchets in b. 14 and 16. Initially, they looked as follows: e1-b1-c2 and c1-e1-g1, respectively. See also b. 23.
