b. 27-28

composition: Op. 10 No 9, Etude in F minor

Indications in AI

A, literal reading

Contextual interpretation of A (→FEGE,EE)

..

Despite the difference in arrangement and number of indications, the character and flow of this phrase were not subject to any change, as it seems. The fact of having written under the 2nd octave in bar 28 in A is most probably an example of a manner of arranging indications near the middle of the scope of their validity and this is how it was interpreted in FE (→GE,EE).

All'ottava sign in AI, A, EE, FED & FES

No all'ottava sign in FE (→GE)

The earlier ending of the octave sign in FE (→GE) is a patent error, corrected by Chopin in FED and FES. Both autographs, as well as EE, have the correct text.

No sign in AI & FE (→GE,EE)

Our variant suggestion

..

According to us, lack of the  hairpins in FE (→GE,EE) is probably a result of the engraver's negligence. However, it is not entirely clear, therefore we leave the inclusion of this mark to the performer's discretion.

b. 29-32

composition: Op. 10 No 9, Etude in F minor

No fingering in AI & A

Fingering in FE (→GE)

..

The fingering in the L.H. in bars 29-31 was added by Chopin in a proofreading of FE (→GE,EE). In EE the indications of bar 31 were also repeated in bar 32.
