b. 1

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

No fingering in AI & FE (→GE)

Fingering in EE

Fingering written into FES

..

In the version prepared for print, the first fingering numerals appear not until bar 12. However, during the lessons with Chopin, the indications concerning the fingering proved to be necessary already earlier. In the main text we consider the fingering written by Chopin in FES. In EE Fontana also offered his suggestion for bar 1, yet this fingering, avoiding the use of the 1st finger on black keys, diverts from the one by Chopin.

In the main text we suggest an indication composed of the elements whose authenticity seems to be most plausible:  written by Chopin's hand in AI and , which is a natural starting point for cresc. in FE (→GE,EE).

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

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

No metronome marking in AI

Metronome marking in FE (→GE,EE)

..

The metronome tempo marking was added – undoubtedly by Chopin – only at the stage of preparing the Etude for print: in [A] or in a proofreading of FE

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.
