composition: Op. 25 No 4, Etude in A minor

in A (→FE)

in FC (→GE) & EE

..

The values of the metronome tempo, both 120 in A and 160 in FC, were written with Chopin's hand, it was most probably also the case in the manuscript base text to EE. Therefore, in the main text we give 160, present in two authentic sources.

b. 1

composition: Op. 21, Concerto in F minor, Mvt III

..

In A the  raising e2 to eis absent. It is difficult to explain this oversight other than by haste. The mistake was corrected already in GE1 (→FEEE,→GE2). In analogous bar 325 a correct sign is present in all sources.

b. 2-4

composition: Op. 50 No. 3, Mazurka in C♯ minor

..

AI is lacking in the sharps restoring f2 in b. 2 and f1 in b. 4. They must be oversights, very typical of Chopin. There is a similar situation in b. 94 and 96.

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.

b. 3

composition: Op. 24 No. 4, Mazurka in B♭ minor

..

A  heightening g1 to g1 is missing from all the sources. The use of g1 between f1 and g1 is so obvious in this context that the error went unnoticed for several dozen years.
