b. 3

composition: WN 17, Polonaise in B♭ major

in JC

G1-G in EF

B1-B in PE

..

Using a chord without third at the beginning of the bar, as it is both in JC and in EF, raises doubts as to the correctness of Chopin's notation reading in [AI]. However, even if that version was intended by Chopin in any stage, later it was replaced by the musically smoother version of PE

b. 3

composition: WN 17, Polonaise in B♭ major

R.H. in JC

..

The version of JC and EF, with a clearly audible doubled leading note B-b on the 5th quaver of the bar, is undoubtedly earlier. It is difficult to determine how the difference concerning sustaining the note at the transition between bars 3 and 4 was developed. In PE, the lower note of the last semiquaver was printed on the level of c1, which is certainly a mistake corrected by us into d1.

composition: Op. 10 No 1, Etude in C major

No fingering in CLI

Fingering in FE (→GE)

Additional fingering in EE

..

The fingering given in the main text, drawn from FE (→GE), is certainly authentic. In EE it was completed with digits added by Fontana, which, in this case, describes an alternative fingering.

b. 3-4

composition: Op. 10 No 2, Etude in A minor

Semiquavers in CLIFE (→GE,EE

Semiquavers & crotchets in Ap

..

In Ap the rhythmic values of subsequent two-note chords of the lower voice in the R.H. create in those bars (as well as in subsequent repetitions) an alternating short-long scheme (semiquaver-crotchet). Sometimes the resounding length contrast is additionally underlined with accents. In the main text we give the homogenous, as far as the sound is concerned, version of FE (→GE,EE).
