b. 8

f1 quaver in AsI (later version)

f1 quaver in AsI (later version)

f1 crotchet in A (→GEFE,EE,FESB)

f1 crotchet in A (→GEFE,EE,FESB)

..

The version in which the last f1 of the upper voice is a quaver comes from the later of the two versions of the orchestral introduction recorded in #ApI – see bars 1-8. This is a holdover from the earlier version that ends with the motif g1-f1 in the  rhythm. In the main text we provide the final version of A and the first editions.

b. 9

composition: Op. 2, Variations, complete

Quaver b1, no grace notes in AsI

Crotchet b1, grace notes in remaining sources

..

The version with the quaver b1 and without the grace notes ending the trill is written twice in AsI, in the main sequence of the score and in the first measure of the solo part, written next to the new version of the orchestral introduction. Chopin later marked the grace notes in the main sequence, but there is no indication that at this stage he also planned to extend the trill to the value of a crotchet.

b. 14

composition: Op. 2, Variations, complete

h2 sustained in A (→GEFE,EE)

No prolongation in FESB

..

The b2 note, provided with a ten., is prolonged to a crotchet in A (→GEFE,EE). It seems to be Chopin's mistake, since such a long value would have to be held also at the beginning of the 2nd half of the bar, which would certainly be a mistake. To avoid doubts, we change it to a quaver, almost exactly corresponding to its actual length. The fact that FESB omitted that extension could have resulted from that erroneous notation, with which the engraver did not know what to do.
