b. 49-56

composition: Op. 63 No. 1, Mazurka in B major

Eight-bar slur in AI

4 slurs in b. 49-52 in FE1 (→GE)

5 slurs in FE2 (→EE)

..

The eight-bar slur of AI is an element of an earlier concept of slurring of this section – see bars 35-36. In the main text we give the proofread version of FE2 (→EE), in which Chopin combined elements of both concepts by adding a four-bar slur over bars 53-56. He introduced an analogous change into bars 57-60 as well.

composition: Op. 63 No. 1, Mazurka in B major

In the main text we add a cautionary  to b, as it was performed in GE3. The accidental is also in AI, perhaps by mistake, since it does not include the necessary  lowering a to a

b. 53-58

composition: Op. 63 No. 1, Mazurka in B major

No slurs in AI

6 slurs in FE (→GE,EE)

6 slurs in brackets suggested by editors

..

Six one-bar slurs in these bars probably replaced the longer slurs present in AI – see the notes on bars 49-56 and 57-60. However, while proofreading FE2 Chopin restored here longer slurs, almost of the same range as in AI. It makes us doubt whether it was supposed to be an addition to the already printed slurs or whether the composer actually wanted to return to the initial concept, and the fact that the shorter slurs remained unchanged resulted from the engraver not having implemented the more labour-consuming part of proofreading (removing an element was much more troublesome than adding an element, considering the then used print method). As we are uncertain as to Chopin's intention, in the main text we give short slurs in brackets, leaving the decision of whether to include them or not to the performer.

composition: Op. 63 No. 1, Mazurka in B major

Continuous slur in AI

3 slurs in FE (→GE,EE)

..

As part of the change of the general concept of slurring of the middle section of the Mazurka (see the note on bars 35-36), Chopin replaced the four-bar slur of AI with 3 shorter slurs while preparing the piece for print. There is a similar situation in bars 57-60 and 61-64.

composition: Op. 63 No. 1, Mazurka in B major

..

In EEC there is no  raising d1 to d1, which, in a version with a key signature including 3 sharps, results in a b-d1 third. It must be an oversight by the engraver of this edition (incidentally, the same notation in AI, in which a key signature containing 5 sharps is valid all the time, results in a b-dthird). See the note in bar 33.
