Semiquaver thirds in CLI

..

On the 4th beat of bars 19, 21 and 23 CLI and Ap have thirds in the lower voice of the R.H. Chopin resigned from the lower notes of these thirds already in the base text for FE. Independently from the number of sounds, there are also differences in rhythmic values: Ap has crotchets here – according to the general scheme in bars 19-24.

Semiquavers in CLI & FE (→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). The last chords in bars 19, 21 and 23 are discussed separately due to differences in the number of sounds, and in bars 20 and 22 – due to their relation to the accents.

e1-b1 in CLI & Ap

b1 & 2 in FEcor

b1 in FE (→GE,EE)
..

The version of CLI and Ap is certainly earlier. Chopin must have deleted e1 already in the base text for FE. The fact that it cannot be a mistake is proved by the fingering digit (2) written under b1 in FEcor (overlooked in finished FE and the remaining editions). Cf. bars 22 and 24.

Quaver & crotchet in CLI

Two crotchets in Ap

Two quavers in FE (→GE,EE) 
..

In Ap the last chords in the R.H. in bars 20 and 22 are crotchets, which creates a kind of rhythmic and articulation accent. The similarity with the original rhythmic value of the chord in bar 22 is coincidental, as in the original version there are no differing values in the bar. In the version for publication Chopin significantly reduced the number of this kind of differences in the part of the L.H. (not to mention the lower voice of the R.H.).

d-a-c1 in CLI (interpretation)

c-a-b in Ap

d-a-b in FE (→GE,EE) 
..

In the sources there are three enharmonically different forms of this chord. Two of them are inaccurately written: in CLI there are no flats lowering d to d and a to a and in FE there is no  lowering d to d (which was corrected both in GE and EE). In the main text we give the notation adopted by Chopin in the version for publication. Cf. bar 22.
