Pitch

b. 46

composition: Op. 24 No. 1, Mazurka in G minor

c1 in the chord in A, FE (→EE) and GE2 (→GE3)

A note missing in GE1

..

The note c1 in the chord at the beginning of the bar is barely visible in A, so in GE1 it was omitted. Chopin added it again in the proofing of FE (→EE), it was also supplemented in GE2 (→GE3).

b. 57

composition: Op. 24 No. 1, Mazurka in G minor

The version of A

d1 not prolonged in GE

A stem and a dot added for d1 in FE (→EE)

The enriched version of FES

..

The versions of A, GE and FE (→EE) differ only in the accuracy of notation of the sustained note d1. In FES Chopin entered a different, melodically richer version of that bar that, in our opinion, may be regarded at least on a par with the version of FE. Cf. bar 59.
