Slurs

b. 1

composition: Op. 10 No 4, Etude in C♯ minor

Slurs in AI

No slurs in FE (→GE,EE)

..

According to us, lack of the slurs connecting the upbeat with the beginning of bar 1 in FE (→GE,EE) should be considered – independently from the reason thereof – as inaccuracy of notation. An accidental omission of one or both marks could have happened both to Chopin himself in [A] and the engraver of FE. Cf. the note to bars 16-17.

b. 1-2

composition: Op. 10 No 4, Etude in C♯ minor

..

The majority of the slurs of AI is written inaccurately, without precise determination of the range, which is natural in a working autograph. Moreover, the intended range is generally easy to interpret and, on many occasions, such as in the discussed bars, it corresponds to the range of the slur of FE (→GE,EE). In the subsequent section of the Etude, where such a kind of substantial relevance seems to take place, we do not notify minor graphic discrepancies.

b. 1-2

composition: Op. 10 No 4, Etude in C♯ minor

..

In AI the slur does not embrace two entire bars, yet its shape and melodic context suggest that Chopin most probably had in mind such slur like in FE (→GE,EE).

b. 3

composition: Op. 10 No 4, Etude in C♯ minor

No slurs in AI

Slurs in FE (→GE,EE)

..

It is hard to determine whether the slurs were already in [A] or whether they were added in a proofreading of FE (→GE,EE). Anyway, the slurs of unquestioned authenticity in this first out of a few similar places – also bars 11, 53 and 61 – may be easily considered as valid also in the remaining ones, devoid of slurring.

b. 4-6

composition: Op. 10 No 4, Etude in C♯ minor

Slur in AI

Slur in FE (→GE1,EE)

Our suggestion

..

Both lack of the slur in bar 6 in AI and in bars 4-5 in FE (→GE1,EE) may be considered as inaccuracy of notation related to the transition to the new line (such situations are very frequent in Chopin's pieces, e.g., in the Etude in F major, No. 8, bars 34-36 and 61 or E major, No. 11 bars 40-42). Taking into consideration the clear slur in the analogous phrase in bars 1-2, in the main text we suggest a similar solution, combining two slurs appearing in the enumerated sources. In GE2 and subsequent GE,s, a slur was added in bar 5.
