Verbal indications

b. 51-52

composition: Op. 10 No 10, Etude in A♭ major

in A

No indication in FE (→GE,EE)

Our variant suggestion

..

It is uncertain whether the omission of e dim. in FE (→GE,EE) was intended by Chopin. Due to the fact that it suits the previous indications of both A and FE, in the main text we give it in brackets, leaving its consideration to the performer's judgment.

The absence of  in the editions, even if it is not a result of Chopin's proofreading in FE, could have been accepted by the composer who seems to be reducing the number of performance indications (mainly dynamic) in many places, leaving more scope for performers in this respect. Cf., e.g., bars 1-16, as well as notes to the Etude in E major, No. 11, bars 1-14 or Etude in C minor, No. 12, bars 2-10.
