Pitch

b. 14

composition: Op. 28 No. 7, Prelude in A major

e-b-d1 in A (→FCGE, →FEEE) & CGS

f-b-d1 in CXI

..

The version in CXI is most probably a mistake by the copyist.

b. 15

composition: Op. 28 No. 7, Prelude in A major

a-e1 in A (→FEEE1) & CGS

e-a-e1 in FC (→GE) & EE2

..

The version of FC (→GE) is most probably a mistake of Fontana. Although the shorter stem of the 3rd crotchet suggests that the additional e was added, it could not have been done by Chopin, who did not proofread FC. That version was introduced – under the influence of GE1 – also in EE2.
