b. 2

composition: Op. 28 No. 14, Prelude in E♭ minor

..

This bar is written in the manuscripts as a repetition of the preceding one. Chopin used two /• marks, written on the bottom stave, at the pitch of the parts of each of the hands. It could have suggested that it should be notes only that should be taken into account when writing out the abbreviation, since in b. 1 the dynamic marks are written over the top stave – see the note on them in b. 1.

c2-e2 in A (→FC,FEEE)

e2-c2 in GE

..

The version of GE is a mistake of the engraver, which is indicated by the concordant version of the remaining sources and by a comparison with analogous motifs in b. 18 as well as in b. 6 and 22.

In A one can see crossed-out pedalling markings, according to which the pedal should be changed every half bar – 3 times  .

b. 2

composition: Op. 2, Variations, complete

..

In the sources, there is no  restoring d1 on the 4th beat of the bar. The mistake resulted from the way the piano reduction was prepared – the R.H. top voice corresponds to the Violin II part, in which there is no need for a , since it does not feature a d1.
