b. 6-8

composition: Op. 25 No 2, Etude in F minor

Slurs in AT

Divided slur in AW

Continuous slur in CDP, GC (→GE), FE & EE

..

In the version prepared for print, Chopin abandoned in this fragment any attempts to suggest any phrase divisions, both structural (AT) and expressive (AW). The written in AW phrase breath effect in the 2nd half of bar 7 (and 26) was used – in the form underlined with articulation – only on the occasion of the last appearance of this fragment (bar 57).

b. 6-8

composition: Op. 25 No 4, Etude in A minor

No signs in A (→FE)

  in FC & EE

  in GE

In the main text we give a pair of   hairpins added most probably by Chopin in FC and base text to EE. The shift of the  sign in GE was probably a result of division of the score into great staves – bar 7 falls at the end of the line.

The sources differ in the range of  hairpins. Taking into account various possibilities of interpretation of the not too carefully written signs in A (also in analogous bar 31) and a possibility of Chopin proofreading of FE (at the reappearance of this bar in the written repetition of bars 1-12), all three variants of the range of this sign can be considered to be potentially corresponding to Chopin's intention. In the main text we give the most possible interpretation of the hairpins of A.
