Pitch

b. 21

composition: Op. 38, Ballade in F major

..

The middle component of the last chord in the R.H. was certainly corrected in GC from f1 to g1. It is hard to state clearly whether it is Gutmann's own correction or whether it was Chopin that noticed and corrected the wrong pitch while reviewing GC. Cf. the annotation in bar 13.

b. 31

composition: Op. 38, Ballade in F major

..

FE1 has an erroneous B instead of as the bottom note of the first crotchet in the L.H. This might have resulted from a slightly too low position of that note in A. The error was corrected in a proofreading of FE2 (→FE3).
