b. 108

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

..

There is no numeral 3 over the triplet in A (→GE1FE). Its absence, although not causing any misunderstanding, is nonetheless a notation error. The numeral was added in EE and GE2 (→GE3).

b. 146

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

No pause in A (→GE1FEEE)

A pause in GE2 (→GE3)

..

In GE2 (→GE3) a pause sign, obvious in this context, was added over the rest in the L.H. part. Making the notation more specific in that manner is advised in the scores of works for more than one performer, but in piano music it is not necessary.
