category imprint: Editorial revisions

b. 15

composition: Op. 50 No. 1, Mazurka in G major

The cautionary natural before g1 was added in the proofreading of FE (→EE). There is a similar situation in b. 39 and 71.

b. 16-17

composition: Op. 50 No. 1, Mazurka in G major

Slur to bar 17 in A1 (→FEEE)

Slur to end of bar 16 in GE

..

Just like in the R.H. part, in the main text we give the ending of the slur on the basis of the principal source, i.e. GE, based on [A2].

b. 17

composition: Op. 50 No. 1, Mazurka in G major

No mark in Afrag, A1, GE & EE

Staccato dot in FE

..

The staccato dot was most probably added by Chopin in the last stage of proofreading of FE, since it is absent in EE. The absence of the mark in GE may be explained by an oversight of the engraver or even of Chopin in [A2], hence we include the dot in the main text. See also b. 21.

b. 17-21

composition: Op. 50 No. 1, Mazurka in G major

2 staccato dots in A1

No marks in FE (→EE)

Dot in bar 21 in GE

..

According to us, the staccato dots under E in the L.H. that appear in the sources in b. 17 and 21 are enough to confirm the composer's intention concerning their presence. The dots are in both bars in A1 and in b. 21 in GE, which means that Chopin wrote them in the autographs in at least three out of four cases (the fourth could have been written indistinctly in [A2], just like both dots in A1, which are also indistinct).
