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.

No F1 in CLI

b. 3

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).

b. 3

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

No mark in FE (→GE,EE

Probable  in Ap

Possible long accent in Ap

..

It is not clear how to understand the signs shaped in the form of accents visible in Ap at the end of bars 3 and 4. Therefore, in both places we offer alternative interpretations. A similar problem appears in analogous bars 11-12, 38 and 39.
