Pitch

b. 52

composition: Op. 10 No 11, Etude in E♭ major

No 8va sign in A (→FEEE3)

With 8va sign in GE (→EE3)

..

The correctness and authenticity of the version of A (→FEEE3) are undeniable, therefore we adopt it in the main text. The version of GE (and EE4), in spite of the fact that from the pianistic point of view it seems to be more natural, may be attributed to the reviser, as Chopin's possible intervention in the shape of GE1 is highly unlikely.
