b. 2-10

b. 2-3

composition: Op. 10 No 6, Etude in E♭ minor

Slurs in A

No slurs in FE (→GE,EE)

..

The inaccurate and unclear slurs of A were ignored in FE (→GE,EE). Their range, particularly in the case of bar 3, is uncertain. We do not include them in the main text, as Chopin did not repeat them in A and in analogous bars 10-11 and 42-43, nor did he add them in a proofreading of FE (cf. bars 47-49).

b. 2-3

composition: Op. 10 No 7, Etude in C major

..

Initially, the slur of A in bar 2 ended on the last note in this bar (same as in bar 1). Chopin, while adding the slur in bar 3, ensured that it is added to the previous one, which can be considered as a template for all similar situations.
