b. 76

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

..

At the beginning of the bar FE1 features an e1 (with a ) in the top voice. The patent mistake was corrected both in FE2 and EE. A pencilled correction is present also in FED

b. 76-77

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

Tie to b in A1

Slur d1-b in FE (→EE)

No tie in GE

Our variant suggestion

..

It is difficult to say whether the absence of the tie of b in GE means that Chopin abandoned the idea of holding that note or whether it is a result of an oversight of the engraver or of Chopin himself. Due to the above reason we suggest a variant solution with the tie in brackets.
In FE (→EE) the tie was misinterpreted as a slur combining the d1 crotchet in b. 76 with the bottom note of the chord at the beginning of b. 77. As all other ties, written in A1 in the same manner, typical of Chopin, were reproduced in FE correctly, the mistake could have been provoked by the fact that b. 76 was written in A1 on a stave above (due to deletions).

b. 76-77

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

Slur to d1 in A1 (→FEEE)

Slur to bar 77 in GE

..

In the main text we give the slur of A1 (→FEEE), just like in the entire final fragment of the Mazurka (b. 73-103). In FE (→EE) there is also an additional slur under the notes – see the note below.

b. 76

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

 in A1, literal reading

Long accent in A1, contextual interpretation

Short accent in FE (→EE) & GE

..

The mark in A1 is clearly longer than the accents in the previous 3 bars as well as than the marks in b. 81-83. In spite of that, according to us, it is to be interpreted as a long accent, which is indicated by its unequivocal graphic relationship with the b minim. Marks of similar length are featured in A1 as long accents, e.g. in b. 6 or 26. The short accent in the editions is most probably an inaccuracy (and certainly in FE).

b. 77

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

Staccato dot in A1

No mark in FE (→EE) & GE

..

In the main text we give the staccato dot, present in A1 only, since it is correlated with the slurring in terms of sources (see the note to b. 74-75). In analogous b. 85 both A1 and GE include a dot.
