b. 29-30

composition: Op. 25 No 10, Etude in B minor

L.H. slur in GC (→GE) & EE

No slur in FE

category imprint: Differences between sources

b. 30-31

composition: Op. 25 No 10, Etude in B minor

Two slurs in GC (literal reading→GE) & EE

One slur in FE, possible interpretation of GC

..

The slurs of GC overlap, so that it cannot be excluded that the intention of the person writing them was to connect them.

b. 31

composition: Op. 25 No 10, Etude in B minor

Metronome in GC (→GE) & EE3

No indication in FE & EE1 (→EE2)

..

The indication of the metronome tempo was added by Chopin in GC in pencil, hence in the last phase of preparing the Stichvorlage manuscripts for print. Differently than at the beginning of the Etude, the composer added the indication only in this copy. In EE3 it was undoubtedly added on the basis of comparison with GE.

b. 31

composition: Op. 25 No 10, Etude in B minor

No signs in GC (→GE) & EE

Pedalling in FE

..

The pedalling – here and in the entire middle section except for bar 35 – was added by Chopin most probably in the proofreading of FE. Cf. bars 34, 39-40, 42, 59-60, 62, 79-80 and 82.
Providing exactly these chords with pedal was undoubtedly related to their span – sustaining all elements of the chord may be infeasible for an average hand, which requires pedal in order to maintain the sound of the bass notes.
