b. 85

composition: Op. 21, Concerto in F minor, Mvt I

..

A typical Chopin oversight – a missing  restoring e2 – was not corrected in any of the editions. It is particularly bizarre in FE where the  before ewas removed, unnecessarily repeated on the 4th semiquaver in A (→GE).

b. 93

composition: Op. 21, Concerto in F minor, Mvt I

..

Traces of erasures and concentration of the notes visible in A in the 2nd half of the roulade prove the fact it was being extended at the time A was written. According to us, originally the group included 15 notes and its 2nd half was the same as in bar 85.

An additional cnote could have been added by Chopin in the proofreading of GE1 (→FEEE). The melodic line of the accompaniment, where the second quaver of each pair is higher than the previous dyad or chord, suggests that the note was probably to be sustained, which was then performed in the proofreading of FE (→EE). It cannot be excluded that the additional cwas printed in GE1 by mistake and left unnecessarily after having added the correct note, a(a Terzverschreibung error). The tie of this note, added in the proofreading of FE (→EE) and eliminating its repetition, would be then a "simplified correction," which would happen in Chopin's works, e.g. in the Polonaise in C minor, Op. 40 No. 2, bar 125. GE2 restored the version of A.

In the main text we give the version of FE as intended or accepted by Chopin. The version of A may be considered an equal variant, whereas the version of GE1 is almost certainly erroneous.
