b. 329-330

composition: Op. 2, Variations, complete

Semiquavers in AsI & A

Quavers in GE1 (→FE,EE,GE2FESB)

..

As in bar 323, in GE1 (→FE,EE,GE2FESB) the semiquaver beams in the top voice were overlooked.

b. 329-330

composition: Op. 2, Variations, complete

..

As in many similar situations, in A the majority of the necessary accidentals are missing – Chopin wrote accidentals only to the 2nd quaver in bar 329 (e2-e3-g3-e4) and the next semiquaver (b3), the penultimate semiquaver in bar 329 (b1), the bottom note of the 2nd triplet in bar 330 (g) and the bottom note of the 6th triplet in bar 330 (d1). Assuming that the accidentals of the first two-quaver figure of the passage are also valid in the second one, all necessary accidentals were already added in GE1 (FE,EE,GE2FESB,GE3). In FE a  to e2 on the 4th L.H. quaver in bar 329 was also added.

b. 330

composition: Op. 39, Scherzo in C♯ minor

Rhythm in EE and an interpretation of GC's script

Rhythm in FE & GE

..

The initial rhythm in RH () is confirmed in EE and also in GC (despite an obvious error - ). Traces of printing edits in FE allow us to see that the rhythm intitially was notated in this edition too but it was changed by Chopin to . We see this variant also in GE, revised most probably based on the rhythm in the earlier phrase, in bars 322 and 326

b. 330-331

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

b-d1 repeated in A (→GE)

b-d1 tied in FE (→EE)

..

The tie of the b-dthird is probably a Chopinesque correction, introduced in the proofreading of FE (→EE).

b. 330

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

f in A (→GE) & EE 

d in FE

..

The version of FE is almost certainly erroneous (in that edition a number of Terzverschreibung mistakes was committed). The error was corrected in EE.
