b. 3

composition: Op. 28 No. 4, Prelude in E minor

..

One can see traces of changing the pitch of the bottom note in the last pair of chords in As. On the basis of the photocopy at our disposal, however, it seems impossible to determine whether f was changed to e or the other way round. We assume that Chopin changed his mind only once and that it is the text of As after corrections that is compliant with the final version.

Separate slurs in As (bars 4-5)

Continuous slur in A (→FCGE, →FEEE)

Separate slurs in CGS (bars 3-4)

..

The divided slurs in As are rather an evidence of Chopin's structural thinking at the time of writing down the idea of the Prelude than a performance indication. The broken slur of CGS is an inaccuracy of notation at the transition to a new line.

Fingering written into FES

No teaching fingering

..

The addition performed in pencil in FES, hardly legible, especially in b. 4, most probably represents two digits (3) marking the fingering and written on the side.
