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.

b. 7

b. 8

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

..

The accidental before the last crotchet of the L.H. is placed inaccurately in A, so it is not clear to which of the lower notes of the chord it was supposed to refer. Most arguments point to the reading of those notes as g-b flat. This is the version given by all the first editions.

b. 13

a1 in A (→GE) and EE3

c2 in FE (→EE1EE2)

..

The version of FE (→EE1EE2), in which the first one of the basic motifs of the Mazurka was distorted, is certainly wrong. The corrections in EE3 were most probably made on the basis of GE1.
