b. 83-84

composition: Op. 10 No 5, Etude in G♭ major

..

Initially, Chopin wrote the part of the L.H. in A one octave too high. He also committed a mistake at the time of writing the part of the R.H. – he overlooked the a1-a2 octave and noticed the error only when he was writing the fourth consecutive erroneous octave. After adding the correct notes, the erroneous ones remained not deleted, yet in spite of that the engraver correctly understood the notation and the text of FE (→GE,EE) is correct.

​​​​​​​ at the beginning of the octave run certainly corresponds to a performance intended by Chopin. The notation of A is an instance of Chopin's using a convention of placing indications inside, and not at the beginning of the range in which they apply.
